However, the impedance of NFB at high frequency range becomes very low and results in a negative effect - the sound becomes hard and dry.\u003cbr\u003eThe NFB type is usually used as it is an easier way to attain a good signal-to-noise ratio.\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003eAs for the \u003cb\u003eCR type\u003c\/b\u003e, a masterpiece preamplifier equipped with the CR type equalizer is the vintage Harman-Kardon model \"Citation IV\".\u003c\/p\u003e\n\u003cp\u003eCR type equalization requires a high gain level and is much more sensitive to tube quality.\u003cbr\u003eSince tube quality will be directly amplified, the finest possible quality tubes are needed for this type of equalizer.

By housing the mains transformer, rectification, and regulation in a physically separate enclosure from the audio circuit, Unison Research eliminates the primary path by which power supply noise couples into the signal stage. The 300B directly-heated triodes serve as the output stage of the preamplifier -- an unusual and demanding choice for a line-stage application, given the 300B's heater current and the challenge of achieving low noise with a DHT tube in a high-gain, low-level circuit. Six 6C45P tubes, a high-transconductance Russian-designed triode, handle the initial gain and driver stages, while ECC82 and ECC83 provide buffering and phase-splitting duties.

An active tape output, an active subwoofer output, and two remote power switch-on circuits for the REFERENCE TUBE monoblock pair complete the connectivity specification.

The Simply 845 integrates both preamplifier and power amplifier in a single chassis using ECC82 tubes for its preamplifier stage -- a more compact, convenient solution at lower cost and complexity. The REFERENCE PRE offers a significantly more elaborate circuit, greater connectivity (including two balanced phono inputs and XLR line inputs), complete power supply isolation, and the ability to drive any power amplifier independently of an integrated amplifier constraint.\u003c\/p\u003e\n\n\u003ch3\u003eWhat is the 6C45P tube used in the REFERENCE PRE?\u003c\/h3\u003e\n\u003cp\u003eThe 6C45P is a high-transconductance triode of Russian origin, originally developed for instrumentation and measurement applications. In audio preamplifier circuits, its high transconductance -- typically three to five times that of a standard ECC82 -- enables voltage gain stages of lower output impedance and reduced noise. In the REFERENCE PRE, Unison Research deploys six 6C45P tubes in the initial gain and driver stages, taking advantage of the tube's linearity at low signal levels to establish a low-noise gain structure ahead of the 300B output stage.\u003c\/p\u003e\n\n\u003ch3\u003eCan the REFERENCE PRE drive amplifiers other than the REFERENCE TUBE?\u003c\/h3\u003e\n\u003cp\u003eYes. The REFERENCE PRE's 500-ohm output impedance is compatible with any power amplifier or integrated amplifier with an input impedance of 5k ohms or higher -- which encompasses virtually every high-end power amplifier currently available. The balanced XLR outputs (derived from the balanced line inputs and phono inputs) allow connection to fully balanced power amplifiers. The built-in remote switch-on circuits are specifically wired for the REFERENCE TUBE monoblock pair but do not restrict the preamplifier's use with other amplifiers.\u003c\/p\u003e\n\n\u003ch3\u003eWhere can I buy the Unison Research REFERENCE PRE in Buffalo, NY or the USA?\u003c\/h3\u003e\n\u003cp\u003eThe Unison Research REFERENCE PRE tube preamplifier is available at Vinyl Sound in Buffalo, NY, USA.

Using four ECC83 (12AX7) double triodes with the first two pairs configured in an \"ionic bias\" parallel arrangement for maximum gain, the Simply Phono employs a completely passive RIAA equalization network accurate to \u003cstrong\u003e±0.2 dB from 20 Hz to 20 kHz\u003c\/strong\u003e. It provides a gain of \u003cstrong\u003e52 dB\u003c\/strong\u003e and supports both moving-magnet and mid-to-high output moving-coil cartridges through switchable input impedance settings of 47k ohm, 100 ohm, 50 ohm, and 22 ohm at 100 pF capacitance. An improved external power supply is included as standard, and the Cherry Wood base continues the Unison Research design tradition. The output impedance is 800 ohms, and the Simply Phono can be integrated into any quality high-end system -- not only Unison Research amplifiers.\u003c\/p\u003e\n\n\u003ch2\u003eFour ECC83 Tubes with Ionic Bias Parallel Gain Stage\u003c\/h2\u003e\n\u003cp\u003eThe Simply Phono's circuit places its four ECC83 tubes in a specific hierarchy: the first two tubes act in parallel as a maximum gain stage using an \"ionic bias\" configuration. Ionic biasing is a technique in which the tube's quiescent operating point is established by the characteristics of the ionic current in the tube's vacuum rather than by an external resistor or fixed voltage, resulting in an extremely low-noise bias arrangement with minimal resistive noise contribution at the initial gain stage where cartridge signal levels are at their smallest. The second two tubes follow in the gain chain, amplifying the signal further before the passive RIAA network. The use of a completely passive RIAA equalization network -- rather than an active feedback RIAA -- means that no feedback loop is introduced into the signal path for equalization purposes; the equalization is applied by a passive RC network with no amplifier gain stage within the feedback correction loop, a technique associated with lower phase distortion and a more natural-sounding tonal curve.\u003c\/p\u003e\n\n\u003ch2\u003eMM and MC Compatibility with Switchable Impedance\u003c\/h2\u003e\n\u003cp\u003eThe Simply Phono accommodates moving-magnet cartridges at the standard 47k ohm input impedance and mid-to-high output moving-coil cartridges at reduced loading impedances of 100, 50, or 22 ohms. The switchable impedance settings allow the user to optimize the damping and frequency response of the connected MC cartridge, as MC cartridges respond to the impedance of the load presented to their coil. At 22 ohms, heavily damped MCs with high internal impedance are loaded optimally; at 100 ohms, most mid-output MCs operate in their preferred range. The 100 pF capacitance setting at each impedance position is appropriate for standard MM cartridge input conditions. A gain of 52 dB is sufficient for MM cartridges and mid-output MC cartridges but may not accommodate the lowest-output moving-coil designs (typically below 0.3 mV), which would require an additional step-up transformer or a dedicated high-gain MC phono stage.\u003c\/p\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePure Class A Valve Phono Stage:\u003c\/strong\u003e Four ECC83 double triodes operating in pure Class A throughout the gain chain.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIonic Bias Parallel First Stage:\u003c\/strong\u003e First two ECC83 tubes in parallel with ionic bias for minimum noise at the maximum gain stage -- the most noise-critical point in any phono preamplifier.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePassive RIAA Equalization:\u003c\/strong\u003e Completely passive RIAA network accurate to ±0.2 dB (20 Hz to 20 kHz) with no active feedback loop for equalization.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSwitchable Input Impedance:\u003c\/strong\u003e 47k ohm (MM), 100 ohm, 50 ohm, 22 ohm settings with 100 pF capacitance for precise MC cartridge loading.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e52 dB Gain:\u003c\/strong\u003e Sufficient gain for MM and mid-to-high output MC cartridges directly, without a step-up transformer.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExternal Power Supply Included:\u003c\/strong\u003e Dedicated external power supply reduces mains noise coupling into the audio circuit.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e800-Ohm Output Impedance:\u003c\/strong\u003e Compatible with any line input of 10k ohm or higher input impedance without frequency response degradation.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCherry Wood Base:\u003c\/strong\u003e Premium Cherry Wood base construction in the Unison Research classic design language.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\n\u003ctable\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n\u003ctd\u003eType\u003c\/td\u003e\n\u003ctd\u003eStereo phono valve preamplifier\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eClass\u003c\/td\u003e\n\u003ctd\u003ePure Class A\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eRIAA Accuracy\u003c\/td\u003e\n\u003ctd\u003ePassive, ±0.2 dB (20 Hz to 20 kHz)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eOutput Impedance\u003c\/td\u003e\n\u003ctd\u003e800 ohm\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eOutputs\u003c\/td\u003e\n\u003ctd\u003e1 x line (RCA pair)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eGain\u003c\/td\u003e\n\u003ctd\u003e52 dB\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eTHD\u003c\/td\u003e\n\u003ctd\u003e0.4% at 1 V output\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eSignal-to-Noise Ratio\u003c\/td\u003e\n\u003ctd\u003e-72 dB\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eInputs\u003c\/td\u003e\n\u003ctd\u003e1 x RCA pair (MM or MC)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eInput Impedance\u003c\/td\u003e\n\u003ctd\u003e47k ohm \/ 100 ohm \/ 50 ohm \/ 22 ohm, 100 pF (switchable)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eFeedback Factor\u003c\/td\u003e\n\u003ctd\u003e0 dB\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eTube Complement\u003c\/td\u003e\n\u003ctd\u003e4 x ECC83 (12AX7)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003ePower Supply\u003c\/td\u003e\n\u003ctd\u003eExternal (included)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eDimensions (W x D x H)\u003c\/td\u003e\n\u003ctd\u003e140 x 290 x 105 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e3 kg (including power supply)\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\n\u003ch3\u003eWhat is the Unison Research Simply Phono?\u003c\/h3\u003e\n\u003cp\u003eThe Unison Research Simply Phono is a pure Class A stereo phono valve preamplifier from Treviso, Italy, using four ECC83 tubes with a passive RIAA network accurate to ±0.2 dB.

The completely passive RIAA equalization network remains at zero feedback (0 dB), preserving the open, phase-coherent character associated with passive equalization topologies. The passive RIAA accuracy of ±0.1 dB across the full 20 Hz to 20 kHz audio band -- tighter than the industry-standard ±0.5 dB target typically specified by competitive products -- ensures that the tonal balance of vinyl recordings is reproduced with the fidelity intended by the recording engineer. THD is 0.1% at 1 V output, a quarter of the Simply Phono's 0.4% figure at the same level. The external power supply reduces the risk of mains noise coupling into the sensitive first gain stage and removes the transformer's magnetic field from proximity to the phono signal circuit.\u003c\/p\u003e\n\n\u003ch2\u003eComprehensive Cartridge Loading with Four Capacitance Settings\u003c\/h2\u003e\n\u003cp\u003eThe Phono One's four switchable capacitance settings -- 100, 200, 320, and 420 pF -- address the cartridge loading requirement for moving-magnet designs more systematically than most competitive phono stages. MM cartridges exhibit a resonant peak at high frequencies whose exact position and magnitude depend on the interaction between the cartridge's inductance and the combined capacitance of the tonearm cable and phono stage input. The correct capacitance load is specified by the cartridge manufacturer (typically between 100 pF and 400 pF) and selecting the nearest available setting on the Phono One brings the cartridge's high-frequency resonance to the intended position, ensuring the treble balance is reproduced as the cartridge designer intended.

The Pro-Ject Phono Box DS3 B is a solid-state design with an active RIAA network and discrete FET input stage, offering a more neutral, extended high-frequency presentation. The Phono One's -80 dB SNR and ±0.1 dB RIAA accuracy are competitive with any phono stage at its level, but the choice between the two ultimately reflects a preference for tube or solid-state harmonic character rather than a specification advantage for either design.\u003c\/p\u003e\n\n\u003ch3\u003eCan the Phono One accommodate very low-output moving-coil cartridges?\u003c\/h3\u003e\n\u003cp\u003eThe Phono One's 54 dB gain is appropriate for cartridges with an output of 0.4 mV or higher -- which includes many mid-output MCs such as the Ortofon Quintet Black, Hana ML, and Dynavector DV-20X2L. For cartridges below 0.3 mV -- such as the Ortofon MC Anna, Lyra Etna, or Koetsu Rosewood Signature Platinum -- a step-up transformer (SUT) ahead of the Phono One's 47k ohm input position is recommended to bring the signal to a level within the Phono One's optimal gain range.\u003c\/p\u003e\n\n\u003ch3\u003eWhat is a passive RIAA equalization network, and why does it matter?\u003c\/h3\u003e\n\u003cp\u003eVinyl records are cut with the RIAA equalization curve -- bass is reduced and treble is boosted during cutting to fit more music on a record and reduce surface noise. A phono preamplifier must apply the inverse curve during playback. In an active RIAA design, this equalization is applied through a negative feedback loop around an amplifying stage. In a passive design like the Phono One's, the equalization is applied by a purely passive RC network with no active feedback loop.

This approach, combined with high-frequency components originally developed for other engineering disciplines, allows the P20 to deliver a noise floor typically reserved for far more expensive preamplifiers. The result is a soundstage described by Hegel as enormous, with deep and rhythmic bass response and the kind of precise timing that communicates the rhythmic momentum of a live performance.

This allows an AV processor or surround receiver to take over volume control for the front left and right channels, making the P20 a transparent pass-through within a hybrid two-channel and home cinema system without any additional configuration.\u003c\/p\u003e\n\n\u003ch3\u003eWhat is the Silicon Germanium transistor technology in the P20?\u003c\/h3\u003e\n\u003cp\u003eSilicon Germanium is a semiconductor material that offers higher electron mobility than standard silicon, enabling transistors to operate with lower noise and faster switching at audio frequencies. Hegel used Silicon Germanium transistors in the P20 to push the noise floor well below what conventional audio transistors can achieve, along with high-frequency components originally designed outside the audio industry — an approach that results in the P20's exceptionally high signal-to-noise ratio and low distortion figures.\u003c\/p\u003e\n\n\u003ch3\u003eDoes the Hegel P20 come with a remote control?\u003c\/h3\u003e\n\u003cp\u003eYes, the P20 includes the Hegel RC8 remote control as standard. The RC8 is machined from a single block of anodized aluminum, matching the finish of the P20 itself, and provides volume, source selection, and mute control. It also functions as a computer playback controller when a Hegel DAC or amplifier is connected via USB or network.\u003c\/p\u003e\n\n\u003ch3\u003eWhat power amplifier pairs well with the Hegel P20?\u003c\/h3\u003e\n\u003cp\u003eThe P20 is designed to partner naturally with Hegel's own power amplifiers such as the H20 or H30A, sharing the same Norwegian design philosophy and balanced XLR connectivity, but its standard XLR and RCA outputs make it compatible with any quality power amplifier.

Within any production batch of transistors, minor parameter deviations are considered normal, but for the extremely low-amplitude signals handled by a reference preamplifier, even small mismatches introduce higher-order harmonic distortion. By measuring individual transistors and pairing only those with identical electrical characteristics, Hegel eliminates this source of coloration entirely. The matched pair is complemented by an internal layout that minimizes signal trace length throughout, reducing the opportunity for electromagnetic interference to corrupt the signal before it reaches the volume attenuator. This minimalist approach, with the signal passing through only two transistors and the attenuator, is a deliberate rejection of complexity as a design virtue: every additional component in a signal path introduces a potential degradation, and the P30A accepts none that are not strictly necessary.\u003c\/p\u003e\n\n\u003ch2\u003eFully Balanced Architecture and SoundEngine Correction\u003c\/h2\u003e\n\u003cp\u003eThe P30A is balanced from input to output, with two complete amplifier circuits, two volume attenuator sections, and two SoundEngine feed-forward correction modules operating in parallel per channel. In a balanced topology, any distortion or noise that is identical on both legs of the differential signal is rejected by the common-mode cancellation inherent to the balanced architecture. Hegel's SoundEngine circuit adds a second independent layer of distortion suppression on top of this, actively monitoring each signal leg for corruption in real time and canceling intermodulation distortion using a feed-forward design. The result is a preamplifier that measures below 0.005% THD and below 0.01% intermodulation, with a signal-to-noise ratio exceeding 130 dB balanced, figures that represent the current state of the art for an analog preamplifier. The P30A's variable output is provided on one XLR balanced connector and two RCA unbalanced connectors, all simultaneously active, with one of the RCA outputs optionally configurable as a fixed-level output for recording or headphone amplifier use.\u003c\/p\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSNR Greater Than 130 dB (Balanced Mode):\u003c\/strong\u003e Exceptional signal-to-noise ratio achieved through hand-matched FET input transistors, a minimal two-transistor signal path, and fully balanced differential topology throughout.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFully Balanced Differential Architecture:\u003c\/strong\u003e Two independent amplifiers, volume attenuators, and SoundEngine modules per channel ensure that all common-mode noise and residual distortion is canceled before the output stage.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHand-Matched FET Input Transistors:\u003c\/strong\u003e Each production unit features transistors personally measured and matched by Hegel founder Bent Holter to ensure identical electrical parameters, eliminating higher-order harmonic distortion at the amplification entry point.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSoundEngine Feed-Forward Distortion Correction:\u003c\/strong\u003e Hegel's patented real-time distortion monitoring and cancellation circuit removes intermodulation distortion as it is introduced, without the phase-related trade-offs of conventional negative feedback.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimal Two-Transistor Signal Path:\u003c\/strong\u003e The music signal passes through only two transistors and an ultra-low-noise volume attenuator, with internal layout optimized for the shortest possible signal traces to minimize electromagnetic interference.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRemote Control of Volume, Source, and Mute:\u003c\/strong\u003e Full remote functionality covering all primary operating functions, with a 3.5 mm IR-direct input for integration into custom installation control systems.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVersatile Input and Output Configuration:\u003c\/strong\u003e Two XLR balanced and three RCA unbalanced inputs, a Home Theatre fixed-level input (also configurable as a standard input), one XLR balanced output, two simultaneous RCA variable outputs, and a fixed-level output option on one RCA.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e12 V Trigger Output:\u003c\/strong\u003e Automates power sequencing with the H30A or other compatible power amplifiers, ensuring correct startup and shutdown order without manual intervention.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMatched Form Factor with H30A and Viking:\u003c\/strong\u003e The P30A's chassis dimensions and styling are coordinated with the H30A power amplifier and the Viking CD player for a cohesive reference system presentation.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\n\u003ctable\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n\u003ctd\u003eInputs\u003c\/td\u003e\n\u003ctd\u003e2 x XLR balanced;

It achieves a signal-to-noise ratio greater than 130 dB in balanced mode through a fully balanced architecture, hand-matched FET input transistors, a two-transistor signal path with an ultra-low-noise volume attenuator, and Hegel's patented SoundEngine feed-forward distortion correction. The P30A is the natural partner for the H30A power amplifier and Viking CD player, sharing a coordinated chassis form factor and an engineering lineage focused entirely on signal transparency.\u003c\/p\u003e\n\n\u003ch3\u003eHow does the Hegel P30A compare to the Pass Labs XP-22?\u003c\/h3\u003e\n\u003cp\u003eThe Pass Labs XP-22 is a two-chassis American reference preamplifier featuring separate power supply and audio boards, widely regarded for its natural tonal balance and Class A-biased output stage. The P30A operates in a single chassis and achieves a higher specified signal-to-noise ratio (130 dB balanced vs. approximately 120 dB for the XP-22) through its fully balanced architecture and matched FET input stage. The XP-22 offers a larger input complement and separate power supply isolation, while the P30A prioritizes the shortest possible signal path and SoundEngine distortion correction as its primary design differentiators. Both are designed to be long-term reference components rather than products subject to rapid obsolescence.\u003c\/p\u003e\n\n\u003ch3\u003eHow does the Hegel P30A compare to the Luxman CL-1000?\u003c\/h3\u003e\n\u003cp\u003eThe Luxman CL-1000 is a Japanese reference tube preamplifier employing Class A triode amplification and a LECUA 1000 electronically controlled attenuator. The P30A is a solid-state design using matched FET transistors and Hegel's SoundEngine feed-forward correction, achieving lower measured noise (130 dB SNR balanced) and lower distortion than tube topologies typically allow. The CL-1000 offers the harmonic character and gain structure of triode amplification, which some listeners prefer for its tonal density, while the P30A provides greater transparency, wider bandwidth, and a more neutral presentation that preserves the sonic character of the source and the power amplifier it drives.\u003c\/p\u003e\n\n\u003ch3\u003eWhy does the signal path use only two transistors?\u003c\/h3\u003e\n\u003cp\u003eThe P30A's two-transistor signal path is a deliberate design choice based on the principle that every active component added to a signal chain introduces a potential source of noise, distortion, or coloration. Conventional preamplifiers often use four to six gain stages to achieve high input sensitivity and wide bandwidth, but each additional stage contributes its own noise floor and non-linearity. Hegel's approach is to begin with transistors whose matched characteristics eliminate higher-order harmonic distortion at the source, apply SoundEngine correction to handle intermodulation distortion, and keep the path as short as physically possible. The fully balanced topology then cancels any common-mode residual. The result is a preamplifier whose measured performance reflects the cumulative benefit of disciplined minimalism rather than the correction of avoidable complexity.\u003c\/p\u003e\n\n\u003ch3\u003eCan the P30A be integrated into a home theater system?\u003c\/h3\u003e\n\u003cp\u003eYes. The P30A includes a dedicated Home Theatre fixed-level input that allows a surround processor's front-left and front-right outputs to bypass the P30A's volume control and feed directly into the amplifier stage at a fixed gain, enabling the surround processor to govern the level for movie playback while the P30A retains full control for stereo music listening. This input can alternatively be configured as a standard variable-level input when home theater bypass is not required. The 12 V trigger output automates power sequencing with the H30A and other compatible amplifiers.\u003c\/p\u003e\n\n\u003ch3\u003eWhere can I buy the Hegel P30A in Buffalo, NY or the USA?\u003c\/h3\u003e\n\u003cp\u003eThe Hegel P30A is available at Vinyl Sound in Buffalo, NY, an authorized Hegel dealer serving audiophiles across western New York and the United States.

Designed by lead engineer Jan Ertner as the dedicated preamplifier component of the premium 9000 Series, the 9000Q pairs the \u003cstrong\u003eESS ES9038PRO 32-bit DAC\u003c\/strong\u003e with a fully balanced differential analogue circuit, delivering a DAC SNR exceeding \u003cstrong\u003e117dB (XLR Direct, A-weighted)\u003c\/strong\u003e and preamp THD below \u003cstrong\u003e0.001%\u003c\/strong\u003e. It accommodates analogue and digital sources across ten inputs — including balanced XLR, three RCA line inputs, a Class A MM phono stage, four S\/PDIF digital inputs, USB-B at PCM 768kHz and DSD512, and Bluetooth 5.1 with aptX HD and LDAC — with three simultaneous variable preamp outputs (two RCA, one XLR), a fixed AUX output, tone controls, digital upsampling, and five selectable digital filters, all controlled through a 4.3-inch full-color IPS LCD display.\u003c\/p\u003e\n\n\u003ch2\u003eESS ES9038PRO DAC, Fully Balanced Signal Path, and XLR Direct Mode\u003c\/h2\u003e\n\u003cp\u003eThe 9000Q's digital conversion platform is built around the ESS ES9038PRO — the same flagship eight-channel 32-bit Sabre DAC found in the 9000A integrated amplifier and 9000N network streamer — implemented here with a dedicated Class A post-DAC active filter and Audiolab's proprietary DC-coupled high-gain circuitry, optimized specifically for the preamp context rather than adapted from an integrated amplifier design. The four S\/PDIF inputs accept PCM up to 24-bit\/192kHz, while the USB-B input handles PCM to 32-bit\/768kHz and native DSD64, DSD128, DSD256, and DSD512. Full certified MQA decoding is performed internally via S\/PDIF and USB inputs. Five user-selectable digital filters allow precise response tailoring, and a digital upsampling mode converts all incoming digital streams to 352.8kHz or 384kHz before conversion. The analogue section employs a differential balanced topology throughout, with a 4-channel analogue volume control as the only element in the direct signal path from input to output. XLR Direct Mode, selectable via the front panel display, maintains a fully balanced signal path from the balanced XLR input through to the XLR preamp output — a dedicated mode for purists seeking the shortest, most transparent analogue route. The 40VA ultra-low-noise toroidal power transformer, combined with advanced power supply filtering derived from Audiolab's DC Block technology series, underpins the 9000Q's measured noise performance: SNR exceeding 113dB via RCA outputs and over 117dB in XLR Direct Mode (both A-weighted).\u003c\/p\u003e\n\n\u003ch2\u003eTone Controls, AV Direct Mode, Headphone Amplifier, and System Integration\u003c\/h2\u003e\n\u003cp\u003eBeyond pure signal transparency, the 9000Q incorporates practical tuning tools that the companion 9000A integrated amplifier does not offer. Accessible via the menu, the tone controls provide independent bass and treble adjustment in 2dB steps across a +\/-6dB range — useful for compensating for room acoustics, speaker voicing characteristics, or personal preference without permanent signal processing. The AUX 3 input can be configured as AV Direct, enabling a direct connection from an AV processor's preamp output with its own volume control, integrating the 9000Q cleanly into a home cinema system without volume conflicts. Three variable preamp outputs — two RCA and one XLR — are fully isolated and can be used simultaneously, allowing connection to multiple power amplifiers or recording devices without mutual interference. A fixed-level RCA AUX output is also provided for connection to a recording device or secondary amplifier at unity gain. The dedicated headphone amplifier employs current-feedback circuitry with wide bandwidth and high slew rate, accommodating loads from 20 to 600 ohms with a 2.35-ohm output impedance, matching the headphone stage specification of the 9000A. Two 12V trigger outputs enable automatic power sequencing of partnering components such as the 9000CDT CD transport, 9000N network streamer, or 9000P power amplifier.

It combines the ESS ES9038PRO 32-bit DAC with a fully balanced differential analogue circuit, ten inputs (including balanced XLR, three RCA line, Class A MM phono, four S\/PDIF digital, USB-B at PCM 768kHz\/DSD512, and Bluetooth 5.1 with aptX HD and LDAC), three simultaneous variable preamp outputs, tone controls, digital upsampling, and a current-feedback headphone amplifier — delivering a DAC SNR exceeding 117dB in XLR Direct Mode.\u003c\/p\u003e\n\n\u003ch3\u003eHow does the Audiolab 9000Q compare to the Rotel RC-1590 MkII, Musical Fidelity M6 PRE, and Parasound Halo P 6?\u003c\/h3\u003e\n\u003cp\u003eThe Audiolab 9000Q distinguishes itself from competing preamplifiers through its integration of a flagship-grade DAC alongside the analogue preamp circuitry. The Rotel RC-1590 MkII (32-bit DAC, no phono, no Bluetooth) provides a clean analogue preamp with basic digital inputs but lacks the 9000Q's ES9038PRO DAC tier, native DSD support, full MQA decoding, and Bluetooth 5.1 with LDAC. The Musical Fidelity M6 PRE (no internal DAC, no digital inputs) is a pure analogue preamplifier without any digital source capability, making it a fundamentally different proposition for those who want to avoid an outboard DAC. The Parasound Halo P 6 (32-bit DAC, MM\/MC phono, no MQA, no Bluetooth) adds moving coil phono compatibility that the 9000Q lacks, but does not match the 9000Q's DAC specification, SNR measurement, full MQA decoding, LDAC Bluetooth, or digital upsampling and filter options.\u003c\/p\u003e\n\n\u003ch3\u003eWhat is XLR Direct Mode and when should I use it?\u003c\/h3\u003e\n\u003cp\u003eXLR Direct Mode is a selectable signal path configuration on the 9000Q in which the analogue input signal travels from the balanced XLR input through only the 4-channel analogue volume control and directly to the balanced XLR preamp output, bypassing all other processing including tone controls and DAC circuitry. This mode is intended for users connecting a balanced analogue source — such as a balanced DAC, network streamer, or CD transport — who want the most transparent and direct signal path possible. In XLR Direct Mode the 9000Q achieves its highest measured SNR of over 117dB (A-weighted), reflecting the inherent noise rejection advantage of balanced differential signal handling throughout.\u003c\/p\u003e\n\n\u003ch3\u003eCan the Audiolab 9000Q be used as the centre of a home cinema system?\u003c\/h3\u003e\n\u003cp\u003eYes. The AV Direct configuration on the 9000Q's AUX 3 input is specifically designed for home cinema integration. When AUX 3 is set to AV Direct, the input bypasses the 9000Q's volume control and accepts a line-level signal directly from an AV processor's preamp output — which has its own volume control — allowing the 9000Q to function as a pure power amplifier driver for the front stereo channels within a surround sound setup. The two 12V trigger outputs also enable automated power sequencing of a partnering power amplifier, such as the 9000P, from the 9000Q's power state.\u003c\/p\u003e\n\n\u003ch3\u003eDoes the Audiolab 9000Q support moving coil (MC) cartridges?\u003c\/h3\u003e\n\u003cp\u003eNo. The 9000Q's onboard phono stage is a Class A moving magnet (MM) design with a 4.5mV input sensitivity and 47K ohm input impedance — values that match the output characteristics of MM cartridges but are not suited to the low-output, low-impedance nature of moving coil designs. Users with an MC cartridge would require an external MC-capable phono preamplifier or step-up transformer connected to one of the 9000Q's RCA line inputs.\u003c\/p\u003e\n\n\u003ch3\u003eIs the Audiolab 9000Q compatible with the 9000A integrated amplifier as a system?\u003c\/h3\u003e\n\u003cp\u003eYes, with some important context. The 9000Q is designed as the dedicated preamplifier for users who want to separate the preamp and power amplifier functions, typically pairing with the companion 9000P power amplifier. The 9000A's Power Amp In socket accepts a line-level signal from the 9000Q's RCA preamp output, enabling the 9000Q to drive the 9000A's 100W power stage directly. In this configuration, the 9000A's own preamp section is bypassed, and the 9000Q takes full control of source selection, DAC processing, volume, and tone adjustment. The system remote control is shared across all 9000 Series components.\u003c\/p\u003e\n\n\u003ch3\u003eWhere can I buy the Audiolab 9000Q in Buffalo, NY or the United States?\u003c\/h3\u003e\n\u003cp\u003eThe Audiolab 9000Q is available at Vinyl Sound, an authorized Audiolab dealer in Buffalo, New York.

The dual-mono layout gives each channel its own independent signal path from input to speaker binding post, with limited capacitive coupling between channels delivering stereo separation measured at 71 to 93dB across the 20Hz to 20kHz range. The CFB (Complementary Feedback) topology ensures superior linearity and consistent thermal stability by keeping idle current independent of output transistor temperature, so the amplifier's distortion and gain characteristics remain stable from cold start through extended listening. A custom-specified 320VA toroidal transformer feeds four 15,000uF reservoir capacitors (60,000uF total), providing the sustained current delivery and dynamic headroom needed to maintain control of demanding speaker loads. Maximum output current is rated at 15A — matching the 9000A specification. A mild Zobel network ensures unconditional stability into any speaker impedance, with the resulting output impedance held between 0.03 and 0.08 ohms across the full audio bandwidth, a figure that directly supports tight low-frequency control regardless of speaker impedance fluctuations.\u003c\/p\u003e\n\n\u003ch2\u003eStereo and Bridged Mono Operation, XLR and RCA Inputs, and System Integration\u003c\/h2\u003e\n\u003cp\u003eThe 9000P offers two operating modes selectable from the rear panel. In standard stereo mode, both channels are active, driven independently from the RCA or XLR inputs. In bridged mono mode, the two amplifier channels are combined to drive a single speaker from a monoblock configuration, delivering 300 watts into 8 ohms or 380 watts into 4 ohms. Two 9000P units configured as monoblocks — one per channel — provide 300 watts per channel into 8 ohms, representing a high-power upgrade path for users with demanding or difficult-to-drive speakers. Both balanced XLR (23dB gain) and unbalanced RCA (29dB gain) inputs are provided on the rear panel, accepting 2Vrms and 1Vrms signals respectively, with a 10K ohm input impedance. A 12V trigger input enables automatic power-on and power-off synchronized with the connected 9000Q preamplifier or other 9000 Series components. Speaker connection is via a set of high-quality gold-plated binding posts. The 9000P's dimensions, aluminium chassis construction, and Black or Silver finish are identical to those of the 9000Q, 9000A, 9000N, and 9000CDT, making it a natural visual and technical match across a complete 9000 Series system stack.\u003c\/p\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDual-Mono Class AB Circuit with CFB Topology:\u003c\/strong\u003e Independent left and right channel signal paths from input to output, with Complementary Feedback ensuring superior linearity, thermal stability, and 71-93dB stereo separation across the audio band.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e100W Per Channel Stereo \/ 300W Bridged Mono:\u003c\/strong\u003e Genuine 2 x 100W into 8 ohms and 2 x 160W into 4 ohms in stereo; 300W into 8 ohms and 380W into 4 ohms in bridged mono mode (single unit).\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBridgeable for Monoblock Operation:\u003c\/strong\u003e Two 9000P units can be configured as monoblocks — one per channel — for 300W per channel into 8 ohms in a high-power dual-chassis setup.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e320VA Custom Toroidal Transformer and 60,000uF Reservoir Capacitance:\u003c\/strong\u003e Identical power supply specification to the 9000A, providing sustained current delivery and dynamic headroom under demanding conditions.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e15A Maximum Output Current:\u003c\/strong\u003e High-current capability supports tight low-frequency control and dynamic transient response with low-impedance and otherwise difficult speaker loads.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBalanced XLR and Unbalanced RCA Inputs:\u003c\/strong\u003e Both balanced and unbalanced inputs provided for maximum preamplifier compatibility, with separate gain settings (23dB XLR \/ 29dB RCA) to match the sensitivity requirements of connected source and preamp components.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUltra-Low Output Impedance:\u003c\/strong\u003e Measured output impedance of 0.03 to 0.08 ohms (20Hz to 20kHz) for strong damping and precise speaker control across the audio band.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGold-Plated Binding Posts:\u003c\/strong\u003e High-quality speaker terminals supporting bare wire, spade, and banana plug connections.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e12V Trigger Input:\u003c\/strong\u003e For automatic power sequencing with the 9000Q preamplifier or other compatible components.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFull 9000 Series Visual Match:\u003c\/strong\u003e Identical form factor (444mm wide, 90mm high), aluminium chassis, and Black or Silver finish matching every other 9000 Series component for a cohesive system stack.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\n\u003ctable\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n\u003ctd\u003eType\u003c\/td\u003e\n\u003ctd\u003eStereo \/ Mono Power Amplifier\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eAmplifier Class\u003c\/td\u003e\n\u003ctd\u003eClass AB, Dual-Mono with CFB (Complementary Feedback) Topology\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eOperating Modes\u003c\/td\u003e\n\u003ctd\u003eStereo; Bridged Mono\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003ePower Output (Stereo)\u003c\/td\u003e\n\u003ctd\u003e2 x 100W (8 ohms, THD \u0026lt; 1%); 2 x 160W (4 ohms, THD \u0026lt; 1%)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003ePower Output (Bridged Mono)\u003c\/td\u003e\n\u003ctd\u003e300W (8 ohms, THD \u0026lt; 1%); 380W (4 ohms, THD \u0026lt; 1%)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eTHD\u003c\/td\u003e\n\u003ctd\u003e\u0026lt; 0.002% (1kHz)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eFrequency Response\u003c\/td\u003e\n\u003ctd\u003e20Hz - 20kHz (+\/- 0.3dB)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eSignal-to-Noise Ratio\u003c\/td\u003e\n\u003ctd\u003e\u0026gt; 112dB (A-weighted)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eGain\u003c\/td\u003e\n\u003ctd\u003e29dB (RCA); 23dB (XLR)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eInput Sensitivity\u003c\/td\u003e\n\u003ctd\u003e1Vrms (RCA); 2Vrms (XLR)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eInput Impedance\u003c\/td\u003e\n\u003ctd\u003e10K ohms\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eMax.

It delivers 100 watts per channel into 8 ohms in stereo mode via a dual-mono Class AB circuit with CFB topology, rising to 300 watts into 8 ohms in bridged mono mode, with a 320VA toroidal transformer, 60,000uF total reservoir capacitance, 15A maximum output current, THD below 0.002%, and both balanced XLR and unbalanced RCA inputs.\u003c\/p\u003e\n\n\u003ch3\u003eHow does the Audiolab 9000P compare to the Parasound Halo A 23+, Rotel RB-1582 MkII, and Cambridge Audio CXA81 MkII power stage?\u003c\/h3\u003e\n\u003cp\u003eThe Audiolab 9000P stands out in its price bracket through its combination of bridgeable mono operation and dual-mono architecture. Against the Parasound Halo A 23+ (125W\/8 ohms, Class AB, no XLR input, no trigger, no bridged mode), the 9000P offers equivalent or greater power, adds balanced XLR connectivity, bridged mono capability, and 12V trigger automation — at a comparable price point. The Rotel RB-1582 MkII (200W\/8 ohms, Class AB, XLR and RCA inputs, no bridged mode) delivers more rated stereo power than the 9000P in stereo, but the 9000P's bridgeable design means a pair of 9000P monoblocks can match or exceed it per channel. The Cambridge Audio CXA81 MkII is an integrated amplifier rather than a dedicated power stage, with 80W per channel sharing a chassis with DAC and preamp circuitry; the 9000P as a dedicated power amplifier eliminates the shared power supply constraints inherent in an integrated design.\u003c\/p\u003e\n\n\u003ch3\u003eWhat is bridged mono mode and when should I use it?\u003c\/h3\u003e\n\u003cp\u003eIn bridged mono mode, the 9000P's two amplifier channels are combined to drive a single loudspeaker, with one channel handling the positive signal phase and the other the negative. This effectively doubles the voltage swing available to the speaker, raising output power from 100 watts into 8 ohms (stereo) to 300 watts into 8 ohms (bridged mono). Bridged mono mode is useful in two scenarios: powering a single speaker with higher headroom than stereo mode allows, or — with two 9000P units — configuring a dedicated monoblock system where each amplifier drives one channel independently at 300 watts per channel. It is most relevant for users with power-hungry or inefficient speakers, or those seeking the sonic benefits of separate monoblock amplification.\u003c\/p\u003e\n\n\u003ch3\u003eCan the Audiolab 9000P be used without the 9000Q preamplifier?\u003c\/h3\u003e\n\u003cp\u003eYes. The 9000P accepts a line-level signal from any preamplifier or source component with a preamp output via its RCA or XLR inputs. Suitable source connections include the Audiolab 9000Q preamplifier (the natural partner), the 9000A's preamp output, the 9000N network streamer's variable analog output, any outboard DAC or network player with a preamp-level output, or a turntable with a phono preamplifier providing a line-level output. The 12V trigger input allows automatic power-on synchronization with any component providing a 12V trigger output.\u003c\/p\u003e\n\n\u003ch3\u003eHow does the Audiolab 9000P differ from the power amplifier stage inside the 9000A integrated amplifier?\u003c\/h3\u003e\n\u003cp\u003eThe 9000P's power amplifier circuit shares the same Class AB topology, CFB design, 320VA toroidal transformer specification, 60,000uF reservoir capacitance, and 15A maximum output current as the 9000A's power stage — but benefits from operating in a dedicated chassis with no competing circuitry sharing its power supply. In the 9000A, the power supply services both the preamp section (including DAC, phono stage, headphone amp, and display) and the power amp stage simultaneously. In the 9000P, the full power supply is devoted exclusively to amplification. The 9000P also introduces bridged mono capability that the 9000A does not offer, and provides the measured improvements in channel separation and SNR that come from the dedicated chassis layout.\u003c\/p\u003e\n\n\u003ch3\u003eIs the Audiolab 9000P stable driving 4-ohm speakers?\u003c\/h3\u003e\n\u003cp\u003eYes. The 9000P is rated at 2 x 160 watts into 4 ohms in stereo mode (380 watts into 4 ohms in bridged mono), and the Zobel network in the output stage ensures unconditional stability into any speaker impedance. The maximum output current of 15A provides the headroom needed to handle the current demands of low-impedance speakers without compression or instability. The output impedance measured at 0.03 to 0.08 ohms across the audio band results in a high damping factor that supports tight bass control with 4-ohm and lower-impedance loads.\u003c\/p\u003e\n\n\u003ch3\u003eWhere can I buy the Audiolab 9000P in Buffalo, NY or the United States?\u003c\/h3\u003e\n\u003cp\u003eThe Audiolab 9000P is available at Vinyl Sound, an authorized Audiolab dealer in Buffalo, New York.

Designed around the principle that the most transparent path between source and amplifier is one that adds nothing and removes nothing, it routes the audio signal through a \u003cstrong\u003eBlue Velvet ALPS potentiometer\u003c\/strong\u003e and a high-grade input selector without any active gain stages, output buffers, or power supply interference. Three RCA inputs, one RCA output, a three-position ground switch for system-specific noise optimization, and a precision 5mm aluminum panel complete a device whose simplicity is its most sophisticated feature.\u003c\/p\u003e\n\n\u003ch2\u003eThe Passive Preamplifier Principle\u003c\/h2\u003e\n\u003cp\u003eA passive preamplifier contains no active gain stages: no tubes, no transistors, no operational amplifiers in the signal path. Volume control is performed purely by attenuation, and the signal passes through only the volume control element and the signal routing switch before reaching the amplifier input. The theoretical advantage is absolute: there is no active circuitry to add noise, distortion, or phase shift to the source signal, and the signal that reaches the amplifier's input is as close to the original source output as the connecting cables and attenuator element allow. The LAB12 True implements this principle with an audio-grade Blue Velvet ALPS potentiometer selected for its channel tracking accuracy and low resistance variation, and a high-grade input selector that provides clean, reliable signal routing without introducing contact resistance or signal degradation.\u003c\/p\u003e\n\n\u003ch2\u003eThree-Position Ground Switch and Precision Build Quality\u003c\/h2\u003e\n\u003cp\u003eThe True includes a three-position ground setting switch on the rear panel, a practical provision that allows the user to select the optimal ground configuration for their specific system. In some system configurations, a fully passive device in the signal chain can interact with the ground topology of connected components to introduce hum or noise. The three-position switch gives the user direct control over this interaction, allowing them to eliminate ground loops or star-ground the passive attenuator to the most appropriate reference in the system without requiring external ground lift adapters or cable modifications. The 50 kΩ input impedance and variable output impedance are characteristic of passive attenuator design, and the amplifier's input impedance should be taken into account when assessing whether a passive stage is appropriate for a given system configuration.\u003c\/p\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFully Passive Signal Path:\u003c\/strong\u003e No active gain stages, buffers, or power supplies in the signal path: the source signal passes through only the volume control and selector switch on its way to the amplifier.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBlue Velvet ALPS Potentiometer:\u003c\/strong\u003e Audio-grade Alps volume control with excellent channel tracking accuracy and low noise for precision attenuation.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHigh-Grade Input Selector:\u003c\/strong\u003e Clean, reliable signal routing for three independent RCA source inputs.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThree-Position Ground Switch:\u003c\/strong\u003e Rear-panel ground configuration switch allows optimal grounding for any system topology, minimizing hum and noise in the specific installation.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThree RCA Inputs:\u003c\/strong\u003e Three stereo line inputs for connecting multiple source components simultaneously.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSingle RCA Output:\u003c\/strong\u003e One stereo line output for connection to a power amplifier or active speakers.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrecision 5mm Aluminum Panel:\u003c\/strong\u003e CNC-machined face panel in Matte Black with a glass-blasted anodized finish and a five-year manufacturer guarantee.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\n\u003ctable\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n\u003ctd\u003eInput Impedance\u003c\/td\u003e\n\u003ctd\u003e50 kΩ\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eOutput Impedance\u003c\/td\u003e\n\u003ctd\u003eVariable (dependent on volume control position)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eInputs\u003c\/td\u003e\n\u003ctd\u003e3 x stereo line (RCA connectors)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eOutput\u003c\/td\u003e\n\u003ctd\u003e1 x stereo line (RCA connectors)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eGround Switch\u003c\/td\u003e\n\u003ctd\u003e3-position rear-panel selector\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eAvailable Color\u003c\/td\u003e\n\u003ctd\u003eMatte Black\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eDimensions (W x H x D)\u003c\/td\u003e\n\u003ctd\u003e12.6\" x 4.3\" x 11.4\"\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e7.7 lb\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eGuarantee\u003c\/td\u003e\n\u003ctd\u003e5 years\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\n\u003ch3\u003eWhat is the LAB12 True?\u003c\/h3\u003e\n\u003cp\u003eThe LAB12 True is a passive preamplifier and input selector from Athens, Greece, containing no active gain stages in the signal path. Volume control is performed by a Blue Velvet ALPS audio-grade potentiometer, source selection by a high-grade input selector, and system ground matching by a three-position rear-panel switch. It provides three RCA inputs and one RCA output in a precision 5mm Matte Black aluminum chassis with a five-year guarantee.\u003c\/p\u003e\n\n\u003ch3\u003eHow does the True compare to the Schiit Sys passive preamp?\u003c\/h3\u003e\n\u003cp\u003eThe LAB12 True and the Schiit Sys are both passive preamplifiers that prioritize signal purity through the elimination of active gain stages, but they are built to substantially different standards. The Schiit Sys is a minimalist two-input passive switcher using a standard potentiometer at a very accessible price, designed for desktop systems or as a simple source selector. The LAB12 True uses a professional-grade Blue Velvet ALPS potentiometer with higher tracking accuracy and lower noise, a more robust input selector, a three-position ground switch for system-specific noise optimization, and the same precision 5mm CNC-machined aluminum chassis and five-year guarantee that characterizes the entire LAB12 range. The True is the more refined choice for listeners building a dedicated high-end passive preamp solution around a power amplifier with sufficient input sensitivity.\u003c\/p\u003e\n\n\u003ch3\u003eIs a passive preamplifier suitable for any power amplifier?\u003c\/h3\u003e\n\u003cp\u003eNot universally. A passive preamplifier delivers best results when the power amplifier it drives has a sufficiently high input impedance (ideally 50 kΩ or greater), sufficient input sensitivity to be driven to full output by the source components' output voltage, and a short, low-capacitance interconnect cable between the passive unit and the amplifier input. Long cable runs increase the interaction between the True's variable output impedance and the cable capacitance, potentially affecting high-frequency response. When these conditions are met, the True offers a level of source transparency that active preamplifiers with shorter signal paths and simpler circuits find difficult to match. Vinyl Sound in Buffalo can help assess whether a passive preamplifier is appropriate for a given system configuration.\u003c\/p\u003e\n\n\u003ch3\u003eWhat does the three-position ground switch do?\u003c\/h3\u003e\n\u003cp\u003eThe three-position ground switch on the rear panel of the True allows the user to select between different ground configurations to optimize the noise performance of the specific system in which the True is installed. In some configurations, the default ground connection of a passive device can interact with the ground topology of source components or power amplifiers to create a ground loop, which manifests as a low-frequency hum in the output. By offering three selectable ground settings, the True allows the user to find the configuration that produces the lowest noise floor in their specific installation without requiring external adapters, cable modifications, or professional intervention.\u003c\/p\u003e\n\n\u003ch3\u003eCan the True be used as a source selector without volume control?\u003c\/h3\u003e\n\u003cp\u003eThe True functions as an input selector in addition to its volume control role, and it can be used to select between three sources by positioning the volume control at a fixed level. However, it does not include a hard bypass or unity-gain fixed-output mode, so the volume potentiometer is always in the signal path. For use purely as a source selector, the potentiometer would need to be set to maximum, which on most ALPS Blue Velvet units corresponds to the full signal passing through the wiper at maximum conductance. This is a valid use case, though a dedicated input selector without a potentiometer in the path would be the technically cleaner choice for pure source switching applications.\u003c\/p\u003e\n\n\u003ch3\u003eWhere can I buy the LAB12 True in Buffalo, NY?\u003c\/h3\u003e\n\u003cp\u003eThe LAB12 True is available at Vinyl Sound in Buffalo, NY, an authorized LAB12 dealer serving Western New York and the USA.

Each channel is assigned its own dedicated AKM AK4191 delta-sigma modulator paired with an AK4499EX D\/A converter — the same dual-chip Velvet Sound combination used in the DMP-A8 — but here implemented in a true dual-mono configuration where neither channel shares any circuitry with the other. Three independent toroidal transformers supply power to the left channel, right channel, and system\/digital domain respectively, with EverSolo specifying power supply noise down to 42 µV. This level of channel independence eliminates crosstalk at the power supply level and ensures that the dynamic behavior of one channel cannot influence the noise floor of the other, translating directly into the 130 dB dynamic range figure and exceptional stereo image stability noted in critical reviews. All digital inputs are electrically isolated to prevent ground loop contamination from reaching the analog conversion stage.\u003c\/p\u003e\n\n\u003ch2\u003eEversolo Precision Core Clock System\u003c\/h2\u003e\n\u003cp\u003eClock quality is a primary determinant of DAC performance, and the DAC-Z10 addresses this with the Eversolo Precision Core system — a three-tier clock architecture combining an OCXO (Oven-Controlled Crystal Oscillator), a phase-locked loop (PLL) jitter suppressor, and an on-board FPGA that reshapes the I2S data stream and refines clock edges before they reach the DAC chips. The OCXO maintains a fixed, thermally regulated internal temperature to eliminate frequency drift from ambient changes, providing a stable reference oscillator regardless of warm-up state or operating duration. The PLL stage locks to this OCXO reference to suppress incoming jitter from USB, coaxial, or optical sources. For reference-level systems, the DAC-Z10 also accepts an external master clock input at 10 MHz or 25 MHz with selectable 50-ohm or 75-ohm termination impedance, enabling synchronization to a dedicated external clock generator for the lowest achievable jitter floor.\u003c\/p\u003e\n\n\u003ch2\u003eFully Balanced Preamplifier, R2R Volume Control, and Analog Inputs\u003c\/h2\u003e\n\u003cp\u003eBeyond its DAC function, the DAC-Z10 includes a fully balanced analog preamplifier stage with dual-channel R2R relay-switched volume control operating independently for each channel, providing analog-domain attenuation with up to +10 dB of gain available for driving power amplifiers or active loudspeakers directly. Analog inputs — both XLR balanced and RCA single-ended — allow the DAC-Z10 to accept non-digital sources through the same R2R volume control and balanced output stage, functioning as a complete analog preamp hub for mixed digital and analog systems. The relay-switched R2R attenuator produces an audible click during volume adjustment, characteristic of relay-based designs, and preserves the full measured dynamic range at all listening levels without the bit-depth penalties of digital volume control. The balanced XLR and single-ended RCA outputs feed power amplifiers directly, simplifying the signal chain by eliminating a dedicated standalone preamplifier.\u003c\/p\u003e\n\n\u003ch2\u003eHeadphone Amplifier, Connectivity, and Display\u003c\/h2\u003e\n\u003cp\u003eThe DAC-Z10 integrates a dedicated headphone amplifier module with a front-panel 6.35 mm output delivering up to 1 W into 16-ohm and 32-ohm loads. Auto impedance detection adjusts the gain profile automatically when headphones are connected, with three selectable gain settings (high, medium, low) available for tailoring output to different headphone sensitivities. The headphone output is single-ended only; no balanced 4-pin XLR or 4.4 mm Pentaconn output is provided. Digital inputs include USB-B (DSD512 \/ PCM 768 kHz \/ 32-bit), I2S over HDMI with eight selectable modes (DSD512 \/ PCM 768 kHz), dual SPDIF coaxial, dual optical Toslink, AES\/EBU, and HDMI ARC — all supporting PCM 24-bit \/ 192 kHz and DSD64 DoP on the SPDIF, optical, and AES inputs. Bluetooth 5.0 is provided via a Qualcomm QCC5125 module supporting SBC and AAC. A 12V trigger input and output enable automated power sequencing. The front panel features an 8.8-inch IPS touchscreen with electromagnetic shielding, displaying VU meters in vintage or modern styles, format information, and full system control.

It delivers measured THD+N of 0.00008% and dynamic range of 130 dB, and includes analog inputs for use as a complete preamp hub. It was launched in November 2025 and is EverSolo's most advanced standalone DAC to date.\u003c\/p\u003e\n\n\u003ch3\u003eHow does the EverSolo DAC-Z10 compare to the Chord Qutest and RME ADI-2 DAC FS?\u003c\/h3\u003e\n\u003cp\u003eThe DAC-Z10 addresses a broader function set than either the Chord Qutest or RME ADI-2 DAC FS while competing on outright DAC performance. The Chord Qutest uses Chord's proprietary FPGA-based WTA filter architecture with no volume control or analog inputs, requiring a separate preamp in all systems. The RME ADI-2 DAC FS offers exceptional measurement performance and a powerful DSP and EQ toolkit but uses a single ESS ES9028Q2M DAC chip without a dual-mono implementation. The DAC-Z10 adds a genuine dual-mono AKM four-chip architecture, three independent toroidal power supplies, R2R relay volume control, analog XLR and RCA inputs for preamp functionality, a headphone amplifier, HDMI ARC, I2S input with eight selectable modes, and an 8.8-inch touchscreen — making it a complete system hub rather than a source-only converter.\u003c\/p\u003e\n\n\u003ch3\u003eCan the EverSolo DAC-Z10 connect directly to a power amplifier?\u003c\/h3\u003e\n\u003cp\u003eThe DAC-Z10 connects directly to a power amplifier via its balanced XLR or single-ended RCA analog outputs, functioning as a full preamplifier with up to +10 dB of analog gain and dual-channel R2R relay volume control. No separate preamplifier is required. The analog inputs allow additional non-digital sources — such as a phono stage or CD player — to be connected through the same volume control and output stage, making the DAC-Z10 a complete signal hub for systems using the EverSolo AMP-F10 or other power amplifiers available at Vinyl Sound in Buffalo.\u003c\/p\u003e\n\n\u003ch3\u003eWhat is the Fully Isolated Architecture (FIA) in the DAC-Z10?\u003c\/h3\u003e\n\u003cp\u003eFIA (Fully Isolated Architecture) is EverSolo's design framework for the DAC-Z10 that enforces complete electrical separation between the left and right channels and between the digital and analog domains. In practical terms, each channel has its own AK4191 modulator, AK4499 converter, signal path, and dedicated toroidal linear power supply, with no shared circuitry between channels at any stage. The digital input stage is electrically isolated from the analog conversion stage to prevent noise from USB, coaxial, or network sources from entering the analog circuit. This architecture directly produces the DAC-Z10's 130 dB dynamic range and eliminates inter-channel crosstalk at both the power supply and signal path level.\u003c\/p\u003e\n\n\u003ch3\u003eDoes the EverSolo DAC-Z10 support external clock input?\u003c\/h3\u003e\n\u003cp\u003eThe DAC-Z10 accepts an external master clock signal at either 10 MHz or 25 MHz with selectable 50-ohm or 75-ohm input impedance, enabling synchronization to a dedicated external clock generator for the lowest achievable system jitter. This feature is designed for reference-level systems where a master clock is distributed to multiple digital components. For most listeners, the onboard Precision Core OCXO clock system provides a reference-grade timing source without an external clock, but the input is available for those building clock-synchronized digital rigs around devices such as the EverSolo T8 streaming transport.\u003c\/p\u003e\n\n\u003ch3\u003eIs the EverSolo DAC-Z10 suitable for headphone listening?\u003c\/h3\u003e\n\u003cp\u003eThe DAC-Z10 includes a dedicated headphone amplifier module with a front-panel 6.35 mm output delivering up to 1 W into 16-ohm and 32-ohm loads, with automatic impedance detection and three selectable gain settings for matching different headphone sensitivities. This output level is sufficient to drive a wide range of full-sized dynamic and planar magnetic headphones. The headphone output is single-ended only — no balanced 4-pin XLR or 4.4 mm Pentaconn output is provided — so listeners using headphones with proprietary balanced cables will need a single-ended adapter.\u003c\/p\u003e\n\n\u003ch3\u003eWhere can I buy the EverSolo DAC-Z10 in Buffalo, NY?\u003c\/h3\u003e\n\u003cp\u003eThe EverSolo DAC-Z10 is available at Vinyl Sound, an authorized EverSolo dealer in Buffalo, New York, serving audiophiles across Western New York.

Digital-to-analog conversion is handled by an OPA1612 op-amp stage on the output, delivering XLR output at 4.2 V and RCA at 2.1 V with a frequency response deviation of only ±0.15 dB from 20 Hz to 20 kHz. The XMOS XU316 USB interface manages all high-resolution USB input, ensuring bit-perfect data transport at rates up to 32-bit\/768 kHz PCM and DSD512. To control jitter, EverSolo implements a dual OCXO (Oven-Controlled Crystal Oscillator) clock system running at 45.1584 MHz and 49.152 MHz — one for each clock domain — keeping oscillators at a stable operating temperature to virtually eliminate frequency drift under sustained use. A high-speed electrical isolation system physically separates the audio circuit boards from digital and display circuits, blocking interference from reaching the analog output stage.\u003c\/p\u003e\n\n\u003ch2\u003eStreaming, Connectivity, and Local Playback\u003c\/h2\u003e\n\u003cp\u003eThe DMP-A10 operates as a fully self-contained streaming and digital hub.

DMP-A10?\u003c\/h3\u003e\n\u003cp\u003eThe EverSolo DMP-A10 is a flagship streaming DAC and preamplifier built around the ESS ES9039 PRO chip, dual OCXO master clocks, and dual low-noise linear power supplies, with a measured dynamic range of 130 dB and THD+N of 0.000078% via XLR balanced output. It functions simultaneously as a music streamer, digital-to-analog converter, digital audio player, and high-fidelity preamp with full input switching, consolidating the core components of a reference-grade hi-fi system into a single full-width chassis. It is EverSolo's flagship product and the most technically advanced device in the DMP lineup.\u003c\/p\u003e\n\n\u003ch3\u003eHow does the EverSolo DMP-A10 compare to the HiFi Rose RS250A and Lumin U2 Mini?\u003c\/h3\u003e\n\u003cp\u003eThe DMP-A10 competes directly with the HiFi Rose RS250A and Lumin U2 Mini in the premium streaming DAC segment but differentiates itself on several fronts. The HiFi Rose RS250A offers a visually elaborate display system but relies on an external DAC path for its best analog output quality. The Lumin U2 Mini is a transport-only device requiring a separate DAC, whereas the DMP-A10 integrates a fully balanced ES9039 PRO DAC stage, a high-fidelity preamp with XLR and RCA outputs, and dual M.2 NVMe SSD slots for internal storage. The DMP-A10's dual OCXO clock system and high-speed electrical isolation are design choices that go beyond what either the RS250A or U2 Mini offer at their respective price points. The DMP-A10 also includes HDMI ARC input and dual subwoofer outputs, extending its utility into home theater integration.\u003c\/p\u003e\n\n\u003ch3\u003eIs the EverSolo DMP-A10 Roon Ready?\u003c\/h3\u003e\n\u003cp\u003eThe DMP-A10 is fully Roon Ready certified, meaning it appears as a native Roon endpoint and receives audio streams from a Roon Core server with full metadata, volume control, and DSP support. It also supports Tidal Connect for direct Tidal app streaming without a Roon subscription. For listeners who prefer to operate without a separate server, the DMP-A10's native app ecosystem covers Tidal, Qobuz, Amazon Music, Apple Music, Deezer, and Highresaudio independently, with DLNA and UPnP for local network playback from a NAS or computer.\u003c\/p\u003e\n\n\u003ch3\u003eWhat does the dual OCXO clock system do in the DMP-A10?\u003c\/h3\u003e\n\u003cp\u003eThe dual OCXO (Oven-Controlled Crystal Oscillator) system uses two thermally regulated crystal oscillators running at 45.1584 MHz and 49.152 MHz, covering both the 44.1 kHz and 48 kHz digital audio clock families respectively. Unlike standard crystal oscillators that drift with ambient temperature changes, OCXO units maintain a fixed internal temperature, minimizing frequency variation over time and under varying load conditions. The practical result is lower jitter at the digital-to-analog conversion stage, which translates to more stable imaging, improved low-level detail retrieval, and reduced digital artifacts during extended listening sessions.\u003c\/p\u003e\n\n\u003ch3\u003eCan the DMP-A10 be used as a standalone music server without a NAS?\u003c\/h3\u003e\n\u003cp\u003eThe DMP-A10 supports two M.2 NVMe SSD slots, each accommodating drives up to 4 TB under the NVMe 3.0 protocol, allowing up to 8 TB of internal storage when both slots are populated with SSDs (sold separately). With internal SSDs installed, the DMP-A10 runs its own music server software, indexing local files and making them available through the device's native interface and the EverSolo app without any external storage hardware. This makes the DMP-A10 a genuinely self-contained playback system for listeners who maintain large local music libraries alongside streaming services.\u003c\/p\u003e\n\n\u003ch3\u003eWhat amplifiers and speakers pair well with the EverSolo DMP-A10 in Buffalo?\u003c\/h3\u003e\n\u003cp\u003eThe DMP-A10's balanced XLR output at 4.2 V makes it well-suited to drive the balanced inputs of high-performance power amplifiers and integrated amplifiers directly, functioning as a reference preamp in a full separates system. Pairing options available at Vinyl Sound in Buffalo include NAD Masters series amplifiers, Bluesound Powernode for streaming integration, and PSB or Klipsch loudspeakers for the speaker end of the chain. The dual subwoofer outputs allow the DMP-A10 to be used directly with active subwoofers such as SVS units without an additional crossover or bass management processor.\u003c\/p\u003e\n\n\u003ch3\u003eWhere can I buy the EverSolo DMP-A10 in Buffalo, NY?\u003c\/h3\u003e\n\u003cp\u003eThe EverSolo DMP-A10 is available at Vinyl Sound, an authorized EverSolo dealer in Buffalo, New York, serving audiophiles across Western New York and the surrounding region. Vinyl Sound provides expert guidance on system integration, amplifier matching, and the full EverSolo lineup including the DMP-A6, DMP-A8, and DMP-A10.

preamplifier, and integrated headphone amplifier from Ferrum Audio (Warsaw, Poland), available at Vinyl Sound in Buffalo, New York. Occupying the same compact 217.5 x 206.5 x 50 mm chassis as the rest of the Ferrum ecosystem, the WANDLA HP builds on the award-winning WANDLA DAC\/Pre architecture by adding a proprietary composite IC headphone amplifier stage tuned specifically for the WANDLA platform. Key headline figures include \u003cstrong\u003e3.5 W into 50 Ω on the balanced 4.4 mm Pentaconn output\u003c\/strong\u003e, a \u003cstrong\u003edynamic range of 122 dB\u003c\/strong\u003e from the headphone section, and full \u003cstrong\u003eESS Sabre ES9038PRO DAC resolution up to 768 kHz\/32-bit and DSD 512\u003c\/strong\u003e. The WANDLA HP sits between the ERCO Gen 2 and the flagship WANDLA plus OOR stack in the Ferrum lineup, offering a single-chassis solution for listeners who want both headphone and loudspeaker system performance from one unit. It is compatible with the HYPSOS Hybrid Power System via the proprietary Ferrum Power Link connector for elevated performance, and supports the WANDLA 2.0.0 firmware update including Ferrum Streaming Control Technology.\u003c\/p\u003e\n\n\u003ch2\u003eIntegrated Headphone Amplifier: Fully Balanced in One Box\u003c\/h2\u003e\n\u003cp\u003eThe headphone amplifier section of the WANDLA HP uses a fully balanced composite IC topology developed in-house by Ferrum and fine-tuned specifically for integration with WANDLA's DAC and preamplifier stages. A single 4.4 mm Pentaconn balanced output is located on the front panel, with a high-quality 4.4 mm to 6.35 mm adapter included in the box for single-ended headphone use. Output power reaches 3.5 W into 50 Ω on the balanced output and 1 W into 50 Ω single-ended. THD on the balanced output measures 0.00016% (-116 dB) at 10 mW into 50 Ω, and headphone output impedance is 0.5 Ω unbalanced and 1 Ω balanced. Dynamic range from the headphone amplifier section is 122 dB. All three gain stages are carried over from the DAC's signal topology, ensuring that the headphone amplifier receives the same fully balanced, zero-compromise signal that the WANDLA platform is known for. The WANDLA HP is also GoldenSound firmware compatible, enabling additional filter and tuning options available from the Ferrum website.\u003c\/p\u003e\n\n\u003ch2\u003eWANDLA DAC and Preamplifier Architecture\u003c\/h2\u003e\n\u003cp\u003eThe DAC section is built around the ESS Sabre ES9038PRO chip and accepts digital sources via USB-C (up to 768 kHz\/32-bit and DSD 512), I2S (PS Audio compatible), AES\/EBU, coaxial S\/PDIF, optical S\/PDIF, and HDMI ARC with CEC. Analogue input via RCA completes the input roster. Line output level reaches 10 V RMS balanced and 5 V RMS unbalanced at 0 dBFS (standard mode) and 4 V RMS balanced and 2 V RMS unbalanced in RED (reduced) output mode. DAC THD measures 0.00009% (-121 dB) and analogue dynamic range is 127 dB (A-weighted). Volume control operates in fully analogue mode with bypass option or digitally for DAC operation. MQA decoding and rendering is supported on all digital inputs. Power consumption is 13 W idle with the headphone amplifier off, 18 W idle with it on, and 35 W maximum. The WANDLA HP accepts both its included 24 VDC adapter and the proprietary four-pin FPL connector from the HYPSOS.\u003c\/p\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n

is a fully balanced DAC, preamplifier, and integrated headphone amplifier manufactured by Ferrum Audio in Warsaw, Poland. It uses the ESS Sabre ES9038PRO chip with DSD 512 support, delivers 3.5 W into 50 Ω on its balanced 4.4 mm headphone output, and achieves a 122 dB dynamic range from the headphone amplifier section. It occupies the same compact 217.5 x 206.5 x 50 mm chassis as the rest of the Ferrum family and is available at Vinyl Sound in Buffalo, New York.\u003c\/p\u003e\n\n\u003ch3\u003eHow does the WANDLA HP compare to the Astell and Kern AK HC4 and the Chord Mojo 2?\u003c\/h3\u003e\n\u003cp\u003eThe WANDLA HP, Astell and Kern AK HC4, and Chord Mojo 2 are all combined DAC and headphone amplifier products, but they serve fundamentally different use cases. The AK HC4 and Mojo 2 are portable USB-powered dongles or pocket devices optimised for on-the-go use with smartphones and laptops. The WANDLA HP is a full-size desktop component with mains power, seven digital inputs including HDMI ARC, analogue RCA input, full preamplifier output at 10 V RMS balanced, and an integrated headphone amp producing 3.5 W into 50 Ω. It functions as a complete desktop hub for both headphone and loudspeaker systems, which neither portable device is designed to do. The WANDLA HP is the appropriate comparison point for desktop all-in-one units such as the Naim Uniti Atom Headphone Edition or the Holo Audio Bliss.\u003c\/p\u003e\n\n\u003ch3\u003eHow does the WANDLA HP compare to the Holo Audio Bliss?\u003c\/h3\u003e\n\u003cp\u003eThe Ferrum WANDLA HP and Holo Audio Bliss are both premium desktop DAC and headphone amplifier combinations aimed at the same audiophile all-in-one market. The Holo Bliss uses Holo's proprietary R-2R discrete ladder DAC architecture, which differs fundamentally from the WANDLA HP's ESS Sabre ES9038PRO delta-sigma approach. The WANDLA HP provides substantially more digital inputs, including HDMI ARC with CEC for home theatre integration and I2S, plus an analogue RCA input not found on the Bliss. The WANDLA HP also offers compatibility with the HYPSOS power supply via FPL cable for power quality improvement, a modular upgrade path unavailable with the Bliss. The Holo Bliss offers a discrete R-2R topology favoured by listeners seeking a non-oversampling or NOS sound character, while the WANDLA HP offers Signalyst-designed HQ Player digital filters for equivalent sonic customisation within a delta-sigma architecture.\u003c\/p\u003e\n\n\u003ch3\u003eWhat is Ferrum Streaming Control Technology (FSCT) and does the WANDLA HP support it?\u003c\/h3\u003e\n\u003cp\u003eFerrum Streaming Control Technology (FSCT) is a feature introduced in the WANDLA 2.0.0 firmware update, available free of charge via the Ferrum Control App for PC and Mac. It allows the WANDLA's touchscreen and included remote control to manage playback on a connected streamer, displaying real-time track information including artist name, title, and a playback progress bar on the DAC's own display. The WANDLA HP is fully compatible with the 2.0.0 firmware update and receives FSCT functionality along with volume synchronisation between the DAC's internal preamp and a connected computer, expanded I2S compatibility, and a favourites input feature for quick source selection.\u003c\/p\u003e\n\n\u003ch3\u003eCan the WANDLA HP be upgraded with the HYPSOS power supply?\u003c\/h3\u003e\n\u003cp\u003eYes. The WANDLA HP includes a proprietary four-pin Ferrum Power Link connector on its rear panel for direct connection to the HYPSOS Hybrid Power System. When connected via FPL cable, the HYPSOS uses its 4T Sensing Design to measure and regulate voltage at the WANDLA HP's internal power rail rather than at the supply output, compensating for cable resistance and continuously correcting voltage under dynamic load. This reduces the noise floor and improves transient response compared to the included standard DC adapter. The HYPSOS Dual Output variant can power both the WANDLA HP and a second Ferrum component such as the OOR simultaneously from a single unit.\u003c\/p\u003e\n\n\u003ch3\u003eWhat headphones work best with the WANDLA HP?\u003c\/h3\u003e\n\u003cp\u003eThe WANDLA HP's balanced output of 3.5 W into 50 Ω is well suited to planar magnetic headphones such as the Audeze LCD-X, Hifiman Arya, and Meze Empyrean, which benefit from the current delivery and low output impedance of 1 Ω balanced. Sensitive dynamic driver headphones including the Sennheiser HD 660 S2 and the Beyerdynamic DT 1990 Pro also pair well, given that the WANDLA HP's analogue volume control and three gain stages accommodate a wide sensitivity range. High-impedance headphones such as the Sennheiser HD 800 S at 300 Ω are within the WANDLA HP's capability, though the separate OOR amplifier with 1,600 mW into 300 Ω balanced will provide additional headroom for the most demanding loads at reference listening levels.\u003c\/p\u003e\n\n\u003ch3\u003eWhere can I buy the Ferrum WANDLA HP in Buffalo or Western New York?\u003c\/h3\u003e\n\u003cp\u003eThe Ferrum WANDLA HP is available at Vinyl Sound, an authorised Ferrum Audio dealer in Buffalo, New York, serving customers across Western New York and the USA.

All WANDLA units including existing owners may install the 2.0.0 update for free via the Ferrum Control App. The WANDLA is winner of the EISA Best DAC 2023-2024 Award and is compatible with the HYPSOS Hybrid Power System via the proprietary Ferrum Power Link connector.\u003c\/p\u003e\n\n\u003ch2\u003eWANDLA 2.0.0: Ferrum Streaming Control Technology\u003c\/h2\u003e\n\u003cp\u003eFirmware version 2.0.0 transforms the WANDLA into what Ferrum describes as the first DAC capable of controlling a music streamer and displaying now-playing information from its own remote control and touchscreen. Ferrum Streaming Control Technology works with sources running macOS, Windows, and Volumio OS, covering the most common computer audio and network streaming platforms. Once connected, the WANDLA's touchscreen displays the current artist, track title, and a playback progress bar, and its included remote control handles transport functions including play, pause, skip, and volume. Volume synchronisation allows the WANDLA's internal analogue preamp volume to be controlled from the connected computer and vice versa, eliminating the need to reach across the desk for level adjustment. Expanded I2S compatibility in the 2.0.0 update broadens the range of compatible sources, and the new favourites input feature allows users to assign a quick-access shortcut to their most-used input. The 2.0.0 firmware is a free download and is compatible with all WANDLA models including the GoldenSound Edition and WANDLA HP.\u003c\/p\u003e\n\n\u003ch2\u003eEISA Award-Winning DAC Architecture\u003c\/h2\u003e\n\u003cp\u003eThe WANDLA's DAC section uses the ESS Sabre ES9038PRO chip with Ferrum's proprietary current-to-voltage (I\/V) conversion stage, fine-tuned in-house for maximum performance from the chip. An optimised ARM processor (SERCE) handles digital signal routing with a signal path short enough to eliminate five otherwise redundant chips. Seven ESS digital filters are available as standard, and four additional filters were created exclusively for Ferrum by Signalyst HQ Player through the Dynamic Digital Filtering (DDF) programme, bringing the total selectable filter count to eleven.

It is built around the ESS Sabre ES9038PRO chip with resolution up to 768 kHz\/32-bit and DSD 256, delivers 127 dB dynamic range (A-weighted), and outputs 9.3 V RMS balanced at 0 dBFS. It is available at Vinyl Sound in Buffalo, New York.\u003c\/p\u003e\n\n\u003ch3\u003eHow does the Ferrum WANDLA compare to the Chord Hugo TT 2?\u003c\/h3\u003e\n\u003cp\u003eThe Ferrum WANDLA and Chord Hugo TT 2 are both flagship-tier desktop DAC and preamplifier units. The Hugo TT 2 uses Chord's proprietary FPGA-based WTA filter technology with no off-the-shelf DAC chip and up to 98,304 taps of digital filtering. The WANDLA uses the ESS Sabre ES9038PRO with eleven selectable digital filters including four created exclusively by Signalyst HQ Player. The WANDLA provides substantially more digital inputs including HDMI ARC with CEC and I2S, and its preamplifier output at 9.3 V RMS balanced is higher than the Hugo TT 2's line output. The WANDLA also accepts an analogue RCA input, which the Hugo TT 2 does not offer. The WANDLA 2.0 firmware adds streamer control and now-playing metadata display, a capability not found on the Hugo TT 2. Both units are compatible with optional dedicated power supply upgrades.\u003c\/p\u003e\n\n\u003ch3\u003eHow does the WANDLA compare to the dCS Bartók?\u003c\/h3\u003e\n\u003cp\u003eThe Ferrum WANDLA and dCS Bartók occupy similar price positioning as reference desktop DAC and preamplifier solutions, but use contrasting architectures. The dCS Bartók uses dCS's proprietary Ring DAC topology, a fully discrete R-2R implementation with dCS's own FPGA-based digital processing. The WANDLA uses the ESS Sabre ES9038PRO chip with Ferrum's proprietary I\/V conversion and the DDF filter programme. The Bartók offers network streaming input natively, while the WANDLA 2.0.0 firmware adds streaming control over connected network devices via FSCT without requiring a built-in streamer module. The WANDLA is substantially more compact at 50 mm height and is priced significantly below the Bartók, while matching or exceeding it on measured THD and dynamic range figures.\u003c\/p\u003e\n\n\u003ch3\u003eWhat is Dynamic Digital Filtering (DDF) on the WANDLA?\u003c\/h3\u003e\n\u003cp\u003eDynamic Digital Filtering is Ferrum's proprietary programme developed in cooperation with Signalyst, the company behind the HQ Player professional audio software. Under DDF, Signalyst created four digital reconstruction filters exclusively for the WANDLA that do not exist in any other DAC, in addition to the seven standard ESS filters the ES9038PRO chip provides. These filters differ in their frequency roll-off behaviour, transient response characteristics, and pre-ringing and post-ringing profiles, allowing listeners to choose the reconstruction algorithm that best matches their headphones, amplification, and personal preference. Selecting a filter is done directly from the WANDLA's touchscreen or remote control with no signal interruption.\u003c\/p\u003e\n\n\u003ch3\u003eDoes the WANDLA 2.0 work as a preamplifier for loudspeakers?\u003c\/h3\u003e\n\u003cp\u003eYes. The WANDLA operates as a full-function preamplifier with variable analogue volume control and bypass option on both its balanced XLR and unbalanced RCA line outputs. The balanced output reaches 9.3 V RMS at 0 dBFS, sufficient to drive virtually any power amplifier to full output. The analogue bypass mode routes the signal through the output stage without volume attenuation, which is useful for fixed-level integration with an external preamplifier. The analogue RCA input with 47 kΩ impedance allows the WANDLA to pass non-digital sources such as phono preamplifiers at line level through to power amplifiers.\u003c\/p\u003e\n\n\u003ch3\u003eCan the WANDLA 2.0 be improved with the HYPSOS power supply?\u003c\/h3\u003e\n\u003cp\u003eYes. The WANDLA includes a proprietary four-pin Ferrum Power Link connector on its rear panel for connection to the HYPSOS Hybrid Power System. Using the FPL cable, the HYPSOS measures voltage directly at the WANDLA's internal rails using its 4T Sensing Design and corrects delivery continuously in real time, eliminating the voltage drop caused by DC cable resistance. This reduces the noise floor and improves dynamic contrast compared to the included standard 24 VDC adapter. Sweet Spot Tuning in the HYPSOS allows the operating voltage to be adjusted from 22 to 30 V on the fly for optimised performance. The HYPSOS Dual Output variant can simultaneously power the WANDLA and the OOR headphone amplifier from a single unit.\u003c\/p\u003e\n\n\u003ch3\u003eWhere can I buy the Ferrum WANDLA 2.0 in Buffalo or Western New York?\u003c\/h3\u003e\n\u003cp\u003eThe Ferrum WANDLA 2.0 is available at Vinyl Sound, an authorised Ferrum Audio dealer in Buffalo, New York, serving customers across Western New York and the USA.

The I\/V converter stage was redesigned for improved linearity and lower noise, and the SERCE DSP engine now runs oversampling using Ferrum's DDF-preferred HQ Apodizing filter as the default reconstruction algorithm, the same class of filter approach used in the flagship WANDLA. Maximum PCM resolution increased from the original ERCO's limit to 768 kHz and maximum DSD resolution increased to DSD 512, with the USB-C input accepting the full DSD 512 natively. These changes make the ERCO Gen 2 substantially closer in technical performance to the WANDLA than its predecessor, which Ferrum acknowledges explicitly. Existing ERCO owners may upgrade their units to Gen 2 specification through Ferrum's official update programme.\u003c\/p\u003e\n\n\u003ch2\u003eFully Balanced DAC and Amplifier Architecture\u003c\/h2\u003e\n\u003cp\u003eThe ERCO Gen 2 uses a discrete and IC hybrid design with ultra-wideband ICs fine-tuned for audio use.

Digital inputs include USB-C for full DSD 512 and 768 kHz PCM, coaxial S\/PDIF up to 192 kHz, and optical S\/PDIF up to 96 kHz guaranteed (potentially higher depending on cable and transmitter). Analogue input via RCA accepts Red Book level (2 V RMS recommended) and Pro level signals. Headphone outputs are the balanced 4.4 mm Pentaconn (TRRRS) and unbalanced 6.35 mm jack.

Gen 2 is a fully balanced integrated DAC and headphone amplifier from Ferrum Audio in Warsaw, Poland. It uses the ESS Sabre ES9028PRO chip with the SERCE DSP engine and DDF HQ Apodizing filter, supports PCM 768 kHz\/32-bit and DSD 512 via USB-C, delivers 6.1 W into 50 Ω on its balanced 4.4 mm headphone output, and achieves 129 dB analogue dynamic range (A-weighted). It won the Headfonia Best DAC\/AMP Combo 2024 Award and is available at Vinyl Sound in Buffalo, New York.\u003c\/p\u003e\n\n\u003ch3\u003eHow does the ERCO Gen 2 compare to the WANDLA plus OOR stack?\u003c\/h3\u003e\n\u003cp\u003eThe Ferrum ERCO Gen 2 and the WANDLA plus OOR combination represent the entry and flagship tiers of the Ferrum desktop ecosystem respectively. The ERCO Gen 2 integrates DAC and headphone amplifier in a single chassis using the ES9028PRO chip, while the WANDLA uses the higher-specified ES9038PRO chip and the OOR is a dedicated fully discrete amplifier with 8 W into 60 Ω balanced versus the ERCO Gen 2's 6.1 W into 50 Ω. The OOR's THD of 0.00011% and dynamic range of 130 dB improve on the ERCO Gen 2's figures of 0.00018% and 129 dB respectively. The WANDLA also offers substantially more digital inputs including AES\/EBU, HDMI ARC, and I2S, which the ERCO Gen 2 does not include. The ERCO Gen 2 shares the same FPL HYPSOS upgrade path and the same DDF filter approach as the flagship, at a considerably lower system cost.\u003c\/p\u003e\n\n\u003ch3\u003eHow does the ERCO Gen 2 compare to the iFi Audio Neo iDSD 2?\u003c\/h3\u003e\n\u003cp\u003eThe Ferrum ERCO Gen 2 and iFi Neo iDSD 2 are both all-in-one desktop DAC and headphone amplifier units aimed at the same audiophile market. The iFi Neo iDSD 2 uses a custom Burr-Brown DAC chip with iFi's proprietary bit-perfect processing and includes Bluetooth 5.4 with LDAC as an additional wireless input. The ERCO Gen 2 does not include Bluetooth but extends to DSD 512 and PCM 768 kHz natively, exceeding the Neo iDSD 2's supported formats. The ERCO Gen 2's analogue dynamic range of 129 dB and balanced output power of 6.1 W into 50 Ω are higher than the Neo iDSD 2's published figures. The ERCO Gen 2 also offers the HYPSOS FPL power upgrade path, which has no equivalent in the iFi product ecosystem.\u003c\/p\u003e\n\n\u003ch3\u003eWhat is the SERCE DSP engine in the ERCO Gen 2?\u003c\/h3\u003e\n\u003cp\u003eSERCE is Ferrum's proprietary ARM-based digital signal processing platform used across the Ferrum product lineup. In the ERCO Gen 2, SERCE provides oversampling computation using the DDF HQ Apodizing filter as the default reconstruction algorithm. This filter was developed in cooperation with Signalyst, the company behind the HQ Player professional audio software, and is the same class of filter used in the WANDLA's Dynamic Digital Filtering programme. SERCE also handles USB audio protocol management, MQA decoding and rendering, and digital input routing, with all ports optimised specifically for audio-grade signal integrity rather than general-purpose USB communication.\u003c\/p\u003e\n\n\u003ch3\u003eCan the ERCO Gen 2 be used as a preamplifier for loudspeakers?\u003c\/h3\u003e\n\u003cp\u003eYes. The ERCO Gen 2 includes balanced XLR and unbalanced RCA line outputs with analogue volume control and bypass option. Line output level is 4 V RMS balanced and 2 V RMS unbalanced at Red Book level, sufficient to drive most power amplifiers to their rated input. The bypass option routes the analogue signal at unity gain without volume attenuation, suitable for integration with an external preamplifier or volume controller. The analogue RCA input accepts both standard Red Book level (2 V RMS) and Pro level signals, allowing use with a phono preamplifier or other line-level analogue sources in a combined headphone and loudspeaker desktop system.\u003c\/p\u003e\n\n\u003ch3\u003e\u003c\/h3\u003e","brand":"Ferrum","offers":[{"title":"ERCO Gen 2","offer_id":53020674162995,"sku":null,"price":2050.0,"currency_code":"USD","in_stock":true},{"title":"ERCO 2 + HYPSOS STACK","offer_id":53020674195763,"sku":null,"price":3445.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0873\/0293\/0739\/files\/FerrumErco2HeadphoneDACAmp_1.png?v=1770136721"},{"product_id":"ferrum-full-headphone-stack","title":"Ferrum FULL Headphone Stack","description":"\u003ch1\u003eFerrum FULL Headphone Stack at Vinyl Sound Buffalo, New York\u003c\/h1\u003e\n\n\u003cp\u003eThe Ferrum FULL Headphone Stack is a complete three-component desktop headphone system from Ferrum Audio (Warsaw, Poland), available at Vinyl Sound in Buffalo, New York. The bundle combines the \u003cstrong\u003eWANDLA DAC\/preamplifier\u003c\/strong\u003e, the \u003cstrong\u003eOOR fully balanced headphone amplifier\u003c\/strong\u003e, and the \u003cstrong\u003eHYPSOS Hybrid Power System\u003c\/strong\u003e into a unified, triple-EISA-Award-winning ecosystem engineered for the most demanding headphone listening. Across the three units, headline figures include \u003cstrong\u003e130 dB dynamic range (A-weighted)\u003c\/strong\u003e from the OOR, \u003cstrong\u003eESS Sabre ES9038PRO DAC resolution up to 768 kHz\/32-bit and DSD 256\u003c\/strong\u003e in the WANDLA, and a programmable DC output voltage range of \u003cstrong\u003e5 to 30 V\u003c\/strong\u003e from the HYPSOS. All three components share an identical chassis footprint of 217.5 x 206.5 x 50 mm, stacking neatly on any desk and connecting internally via Ferrum's proprietary Ferrum Power Link (FPL) cable for optimised power delivery and deepened feedback sensing between units.\u003c\/p\u003e\n\n\u003ch2\u003eWANDLA: Reference DAC and Preamplifier\u003c\/h2\u003e\n\u003cp\u003eThe WANDLA is built around the ESS Sabre ES9038PRO chip and operates in fully balanced mode throughout. It accepts digital sources via USB-C (up to 768 kHz\/32-bit and DSD 256), I2S (PS Audio compatible), AES\/EBU, coaxial S\/PDIF, optical S\/PDIF, and HDMI ARC with CEC control for home theatre integration. Analogue input via RCA with a 47 kΩ input impedance completes the source roster. The DAC section delivers THD of 0.00009% (-121 dB) and a dynamic range of 127 dB (A-weighted), while the balanced XLR output reaches 9.3 V RMS at 0 dBFS. Volume control operates in either fully analogue mode (with bypass option) or digitally for DAC operation, giving users flexibility across both headphone and loudspeaker system configurations. Four proprietary Signalyst HQ Player filters ship alongside the standard ESS filters, allowing listeners to tailor the DAC's digital reconstruction to their preference. MQA decoding and rendering is supported across all digital inputs. Power consumption is 10 W idle, rising to 15 W maximum, and the WANDLA accepts both its included 24 VDC adapter and the proprietary four-pin FPL connector from the HYPSOS.\u003c\/p\u003e\n\n\u003ch2\u003eOOR: Fully Balanced Discrete Headphone Amplifier\u003c\/h2\u003e\n\u003cp\u003eThe OOR is a purely analogue, fully discrete, fully balanced headphone amplifier with no integrated circuits in its signal path. On the balanced output, it delivers \u003cstrong\u003e1,600 mW into 300 Ω\u003c\/strong\u003e and \u003cstrong\u003e8 W into 60 Ω\u003c\/strong\u003e, with THD of 0.00011% at 1 mW into 50 Ω. The dynamic range measures 130 dB (A-weighted), and output impedance at the headphone jack is below 0.3 Ω. Gain is selectable in three steps: -4\/+6\/+16 dB balanced, and -10\/0\/+10 dB single-ended, accommodating both sensitive in-ear monitors and high-impedance planar magnetic headphones. Inputs are balanced XLR and unbalanced RCA, with both a 4-pin balanced XLR headphone output and a standard 6.35 mm single-ended jack. Frequency response extends from 20 Hz to 100 kHz within 0.1 dB. When connected to the HYPSOS via FPL cable, the HYPSOS senses voltage directly at the OOR's internal rails and continuously corrects delivery in real time, a capability not available via any standard DC connection.\u003c\/p\u003e\n\n\u003ch2\u003eHYPSOS: Hybrid Power System\u003c\/h2\u003e\n\u003cp\u003eThe HYPSOS combines linear and switching power supply topologies in a single compact chassis. Its output voltage is continuously adjustable from 5 to 30 V, covering a wide range of audio components beyond the Ferrum family. The proprietary 4T Sensing Design (4TSD) measures voltage at the load rather than at the supply output, compensating for cable resistance and ensuring flat voltage delivery regardless of current draw. A Sweet Spot Tuning function allows fine-grained voltage adjustment to identify the precise operating point at which a connected device performs best. Maximum continuous output power is 80 W for voltages above 13.3 V, and maximum impulse current reaches 9 A (270 W peak at 30 V).

Each unit occupies an identical 217.5 x 206.5 x 50 mm chassis and connects to the others via proprietary Ferrum Power Link cables. Every component in the stack has independently won an EISA Award in its category, making this a triple-award-winning system available at Vinyl Sound in Buffalo, New York.\u003c\/p\u003e\n\n\u003ch3\u003eHow does the Ferrum FULL Stack compare to the Chord Electronics Hugo TT 2 and DAVE?\u003c\/h3\u003e\n\u003cp\u003eThe Ferrum FULL Stack and Chord Electronics DAVE + Hugo TT 2 represent two different engineering philosophies for flagship desktop headphone systems. Chord's approach centres on proprietary FPGA-based digital processing using Robert Watts' WTA filter algorithm, with no off-the-shelf DAC chip and a single-box-per-function architecture. The Ferrum stack uses the ESS Sabre ES9038PRO chip with four additional Signalyst HQ Player filters and separates the power supply into a dedicated chassis to provide cleaner, sensing-corrected DC to both the DAC and amplifier. The OOR delivers 8 W into 60 Ω balanced versus the Hugo TT 2's 1 W into 8 Ω, giving the Ferrum stack a substantial output power advantage for planar magnetic and high-impedance dynamic headphones. The Ferrum system also provides significantly more digital inputs, including HDMI ARC and I2S, and offers a fully variable analogue volume stage with bypass, giving it broader system integration flexibility.\u003c\/p\u003e\n\n\u003ch3\u003eHow does the Ferrum OOR compare to the Benchmark HPA4 headphone amplifier?\u003c\/h3\u003e\n\u003cp\u003eThe Ferrum OOR and Benchmark HPA4 are both fully balanced, low-distortion solid-state headphone amplifiers in the high-end desktop category. The Benchmark HPA4 uses a passive transformer-based volume control and is designed primarily as a reference measurement tool with a focus on vanishingly low noise figures. The OOR uses a fully discrete proprietary power amplifier topology with no integrated circuits and is specifically designed to benefit from external power conditioning via the HYPSOS FPL connection, a feature the HPA4 does not offer. The OOR's balanced output power of 8 W into 60 Ω exceeds the HPA4's output capability for low-impedance loads, and the OOR provides three switchable gain stages allowing it to serve both sensitive IEMs and demanding planar magnetic headphones from the same unit. The HYPSOS sensing connection elevates the OOR's measured noise floor and dynamic range beyond its already competitive standalone specifications.\u003c\/p\u003e\n\n\u003ch3\u003eWhat is the Ferrum Power Link (FPL) connection and why does it matter?\u003c\/h3\u003e\n\u003cp\u003eThe Ferrum Power Link is a proprietary four-conductor DC cable that carries both the power supply voltage and a separate feedback sensing signal between the HYPSOS and the connected component. Standard DC cables deliver power only, meaning the supply regulates voltage at its own output terminals rather than at the actual load inside the amplifier or DAC. The FPL cable routes a sensing wire directly to the internal power rail of the OOR or WANDLA, allowing the HYPSOS to measure and correct voltage at the point of consumption rather than at the socket. This eliminates the voltage drop caused by cable resistance and enables real-time continuous correction of transient demands as the amplifier draws current during musical peaks. The audible result is tighter bass control, lower noise floor, and improved dynamic contrast compared to operating either the OOR or WANDLA on a standard power adapter.\u003c\/p\u003e\n\n\u003ch3\u003eCan the Ferrum WANDLA be used as a preamplifier to drive power amplifiers and loudspeakers?\u003c\/h3\u003e\n\u003cp\u003eYes. The WANDLA functions as a fully featured preamplifier with variable output on both its balanced XLR and unbalanced RCA outputs, making it directly connectable to any power amplifier or active loudspeakers. Analogue volume control operates in a bypass mode for pass-through at unity gain, and digital volume control is available when operating the DAC section. The balanced XLR output reaches 9.3 V RMS at 0 dBFS, which is sufficient to drive virtually any power amplifier to full output. The analogue RCA input with 47 kΩ impedance also allows the WANDLA to serve as a preamp for non-digital sources such as phono preamplifiers. In a full Ferrum system, the WANDLA feeds the OOR headphone amplifier via XLR for headphone listening and can simultaneously output to speakers via the RCA outputs for a shared-source dual-use desktop configuration.\u003c\/p\u003e\n\n\u003ch3\u003eWhich headphones pair best with the Ferrum OOR amplifier?\u003c\/h3\u003e\n\u003cp\u003eThe OOR is designed to drive all headphone types from a single unit, thanks to its three selectable gain stages. High-impedance dynamic headphones such as the Sennheiser HD 800 S (300 Ω), Beyerdynamic T1 (600 Ω), and Audeze LCD-4 planar magnetics benefit most from the OOR's balanced output of 1,600 mW into 300 Ω, which delivers ample headroom and dynamic authority. The lowest gain settings (-4 dB balanced, -10 dB single-ended) make the OOR equally suited to sensitive IEMs without introducing audible noise floor. The output impedance below 0.3 Ω at the headphone jack ensures flat frequency response and damping factor is maintained regardless of headphone impedance curve. The OOR drives both the 4-pin XLR balanced format used by Audeze, ZMF, and Hifiman, and the standard 6.35 mm jack for single-ended operation.\u003c\/p\u003e\n\n\u003ch3\u003eDoes the HYPSOS work with components from other brands besides Ferrum?\u003c\/h3\u003e\n\u003cp\u003eYes. The HYPSOS is designed as a universal audiophile power supply with a continuously adjustable output from 5 to 30 V DC, making it compatible with a wide range of audio components that accept external DC power. Compatible devices include streamers, DACs, headphone amplifiers, phono preamplifiers, and network switches from numerous manufacturers. The 4T Sensing Design function is only active when using the proprietary FPL cable with Ferrum components, but standard DC operation via the 5.5 mm barrel connector is fully available for third-party devices. The adjustable voltage range and Sweet Spot Tuning function allow users to identify the optimal operating voltage for each connected device, which often differs from the manufacturer's nominal specification. Ferrum maintains a compatibility list on their website covering confirmed third-party products.\u003c\/p\u003e\n\n\u003ch3\u003eWhere can I buy the Ferrum FULL Headphone Stack in Buffalo or Western New York?\u003c\/h3\u003e\n\u003cp\u003eThe Ferrum FULL Headphone Stack is available at Vinyl Sound, an authorised Ferrum Audio dealer located in Buffalo, New York, serving customers across Western New York and the broader USA.

Winner of the \u003cstrong\u003eEISA Best Product 2021-2022 Award\u003c\/strong\u003e, the HYPSOS redefines what an audiophile power supply can do by combining a linear and switching topology in a single chassis, with a continuously adjustable DC output from \u003cstrong\u003e5 to 30 V\u003c\/strong\u003e and a maximum continuous output power of \u003cstrong\u003e80 W at voltages above 13.3 V\u003c\/strong\u003e. Its proprietary 4T Sensing Design measures voltage directly at the load's internal power rail via the Ferrum Power Link cable, continuously correcting for cable resistance and transient current demands that standard DC supplies cannot address. The HYPSOS is compatible with the full range of Ferrum Audio components including the OOR, WANDLA, WANDLA HP, and ERCO Gen 2, and with hundreds of third-party audio devices across the 5 to 30 V operating range.\u003c\/p\u003e\n\n\u003ch2\u003eHybrid Linear-Switching Topology\u003c\/h2\u003e\n\u003cp\u003eThe HYPSOS's power conversion stage combines a linear transformer-based section with a switching regulator in a configuration that Ferrum terms a hybrid design. The linear section provides the low ripple, low noise floor, and absence of high-frequency switching interference that audiophile equipment demands, while the switching section contributes fast transient response and high efficiency that a pure linear design cannot match at this output power level. A two-stage EMI filter on the IEC C14 mains inlet provides pre-filtering of mains-borne interference before the conversion stage, further reducing the noise contribution to the DC output. The result is a supply with the noise characteristics of a linear design and the dynamic response of a switching design.\u003c\/p\u003e\n\n\u003ch2\u003e4T Sensing Design and Ferrum Power Link\u003c\/h2\u003e\n\u003cp\u003eThe 4T Sensing Design is the technical core of the HYPSOS's performance advantage over standard power supplies. Most DC power supplies regulate voltage at their own output terminals, meaning the voltage actually reaching the load's power rails is lower than the set point due to resistance in the DC cable. Under dynamic current demands such as musical transients, this voltage sag worsens further as more current is drawn. The FPL cable's four conductors dedicate two to power delivery and two to a sensing circuit that reads voltage directly at the load's internal rail. The HYPSOS continuously compares the sensed voltage against the set point and adjusts its output to correct the difference in real time, ensuring flat voltage at the point of consumption regardless of cable resistance or current demand. Sweet Spot Tuning allows the set point to be adjusted on the fly during playback for direct comparison at different operating voltages.\u003c\/p\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEISA Best Product 2021-2022:\u003c\/strong\u003e The HYPSOS won the Expert Imaging and Sound Association's top product award across all categories in its first year, establishing Ferrum Audio's reputation as a benchmark power supply designer.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e5 to 30 V Adjustable Output:\u003c\/strong\u003e Continuous voltage adjustment with no stepped increments covers virtually all DC-powered audiophile components from both Ferrum and third-party manufacturers, from 5 V network switches to 30 V high-voltage amplifier stages.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e80 W Maximum Continuous Output:\u003c\/strong\u003e Maximum continuous output power of 80 W at voltages above 13.3 V, with 9 A maximum impulse current (270 W peak at 30 V), provides substantial headroom for demanding audio components under dynamic programme material.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e4T Sensing Design via FPL:\u003c\/strong\u003e Voltage sensing at the load rather than at the supply output eliminates DC cable resistance error and enables real-time continuous correction, a fundamental technical advantage over any standard two-wire DC supply.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSweet Spot Tuning (SST):\u003c\/strong\u003e Voltage adjustable on the fly during playback for direct comparative listening at different operating voltages, identifying the specific level at which each connected device performs best.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAdvanced Automation:\u003c\/strong\u003e Trigger input and output connectors support system-level power sequencing, and Apple TV remote compatibility enables voltage adjustment without physical access to the unit.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eComprehensive Protection:\u003c\/strong\u003e Automatic Transformer Voltage Adjust (ATVA), electronic output polarity switching, and overvoltage, overcurrent, and short-circuit protection circuits safeguard connected components.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUniversal Third-Party Compatibility:\u003c\/strong\u003e The 5.5 mm barrel DC output in 5.5 x 2.5 mm and 5.5 x 2.1 mm variants connects to the majority of DC-powered audio components on the market;

It delivers a continuously adjustable DC output from 5 to 30 V with 80 W maximum continuous output power, uses 4T Sensing Design via the Ferrum Power Link cable to regulate voltage at the load's internal rail rather than at the supply output, and won the EISA Best Product 2021-2022 Award. It is available at Vinyl Sound in Buffalo, New York, as a standalone unit and as an upgrade for the OOR, WANDLA, WANDLA HP, and ERCO Gen 2.\u003c\/p\u003e\n\n\u003ch3\u003eHow does the HYPSOS compare to an iFi iPower Elite or Paul Hynes SR4?\u003c\/h3\u003e\n\u003cp\u003eThe Ferrum HYPSOS, iFi iPower Elite, and Paul Hynes SR4 are all audiophile-grade external power supplies, but they differ significantly in topology and capability. The iFi iPower Elite is an active noise-cancelling switching supply with fixed output voltages, designed for compact low-power components. The Paul Hynes SR4 is a pure linear supply with fixed or semi-adjustable output voltage, known for very low noise but limited output current and no automated voltage sensing. The HYPSOS uniquely combines a hybrid linear-switching topology with a continuously adjustable 5 to 30 V output, 80 W maximum output power, and the 4T Sensing Design that neither the iPower Elite nor the SR4 offers. The HYPSOS also includes full system automation via trigger and Apple TV remote, which are absent from the competing products.\u003c\/p\u003e\n\n\u003ch3\u003eDoes the HYPSOS Single Output include the Ferrum Power Link cable?\u003c\/h3\u003e\n\u003cp\u003eThe HYPSOS ships with a DC power cable in the most commonly used connector size (5.5 x 2.5 mm or 5.5 x 2.1 mm). The Ferrum Power Link FPL cable required for 4T Sensing connection to OOR, WANDLA, WANDLA HP, or ERCO Gen 2 is a separate purchase. The FPL cable is available at Vinyl Sound Buffalo and is required to activate the 4T Sensing Design; without it, the HYPSOS operates as a conventional regulated DC supply via the standard barrel connector. Custom cable lengths are available to order.\u003c\/p\u003e\n\n\u003ch3\u003eWhat voltage should I set the HYPSOS to when using it with the Ferrum OOR or WANDLA?\u003c\/h3\u003e\n\u003cp\u003eFerrum recommends 24 V as the starting operating voltage for both the OOR and WANDLA when connected via the HYPSOS. The safe adjustment range via FPL is 22 to 30 V. Sweet Spot Tuning allows the user to adjust voltage on the fly during playback in small increments to identify the level at which their specific unit sounds best in their system. Different units may respond differently to voltage variations due to component tolerances, and the optimal level may differ slightly between the OOR and WANDLA. For third-party components, consult the device's documentation for its rated DC input voltage before connecting the HYPSOS.\u003c\/p\u003e\n\n\u003ch3\u003eCan the HYPSOS Single Output power two components using a Ferrum Power Splitter?\u003c\/h3\u003e\n\u003cp\u003eYes. The Ferrum Power Splitter accessory connects to the HYPSOS Single Output and provides two DC output cables for simultaneously powering two components at the same voltage. When using the Power Splitter, both connected devices must be compatible with the same operating voltage and combined power consumption must not exceed 80 W or 6 A. The 4T Sensing Design via FPL cable remains active on one output of the Power Splitter. Users who need two simultaneous outputs as a primary system configuration may prefer the HYPSOS Dual Output, which integrates dual output capability into the supply directly.\u003c\/p\u003e\n\n\u003ch3\u003eIs the HYPSOS software upgradeable?\u003c\/h3\u003e\n\u003cp\u003eYes.

The same voltage level is applied to both outputs simultaneously, meaning both connected devices must be compatible with the selected operating voltage. Combined continuous output current across both outputs is 6 A and combined maximum continuous output power is 60 W. The 4T Sensing Design is active only on the main output via the FPL cable connection, providing the full sensing-corrected voltage regulation for the primary Ferrum component such as the OOR or WANDLA. The secondary output delivers regulated voltage without FPL sensing, operating as a conventional high-quality regulated DC supply for the second connected device. Sweet Spot Tuning voltage adjustment applies to both outputs simultaneously.\u003c\/p\u003e\n\n\u003ch2\u003eHybrid Linear-Switching Topology and 4T Sensing Design\u003c\/h2\u003e\n\u003cp\u003eThe HYPSOS combines a linear power supply topology with a switching supply in a single chassis to capture the advantages of each approach. The linear section provides the low ripple, low noise, and absence of switching interference associated with transformer-based designs, while the switching section contributes fast transient response and high efficiency. The two-stage EMI filter on the IEC C14 mains inlet provides additional rejection of mains-borne noise before the power conversion stage. The 4T Sensing Design uses a four-conductor Ferrum Power Link cable to route a dedicated sensing wire directly to the load's internal power rail, allowing the HYPSOS to measure voltage at the point of consumption and continuously correct delivery in real time. This eliminates the effect of DC cable resistance that standard two-wire power delivery cannot compensate for, resulting in flat voltage at the load under all dynamic current demand conditions.\u003c\/p\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEISA Best Product 2021-2022 Platform:\u003c\/strong\u003e Built on the HYPSOS Single Output, which won the Expert Imaging and Sound Association's top product award for 2021-2022, the Dual Output version extends the same platform to two-component systems.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTwo Simultaneous DC Outputs:\u003c\/strong\u003e Powers two compatible audio components from a single mains connection, reducing cable clutter and system complexity on a desktop with OOR, WANDLA, ERCO Gen 2, or compatible third-party devices.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e60 W \/ 6 A Combined Continuous Output:\u003c\/strong\u003e Total output capacity across both channels supports simultaneous operation of two power-demanding audio components with headroom to spare for transient demands.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e4T Sensing Design on Main Output:\u003c\/strong\u003e Proprietary sensing technology routes voltage measurement directly to the load's internal rail via the FPL cable on the main output, compensating for cable resistance and correcting voltage under dynamic current draw.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e5 to 30 V Adjustable Voltage:\u003c\/strong\u003e Continuously adjustable output voltage covers virtually all DC-powered audiophile components from both Ferrum and third-party manufacturers, future-proofing the power supply investment.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSweet Spot Tuning (SST):\u003c\/strong\u003e Output voltage can be adjusted on the fly during playback, allowing direct comparative listening at different operating voltages to identify the optimal performance point for connected devices.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAdvanced Automation:\u003c\/strong\u003e Trigger input and output connectors allow integration with system power-up sequences, and Apple TV remote compatibility enables voltage adjustment from a standard remote control without approaching the unit.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eComprehensive Protection:\u003c\/strong\u003e Automatic Transformer Voltage Adjust (ATVA), electronic output voltage polarity switching, and overvoltage, current limit, and short-circuit protection guard connected components against accidental damage.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\n\u003ctable\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n\u003ctd\u003ePower Input\u003c\/td\u003e\n\u003ctd\u003e110-120 V AC \/ 220-240 V AC, 50-60 Hz (EU\/US);

It is built on the platform of the EISA Best Product 2021-2022 HYPSOS Single Output and adds a second output channel for powering two audio components simultaneously. It is available at Vinyl Sound in Buffalo, New York.\u003c\/p\u003e\n\n\u003ch3\u003eHow does the HYPSOS Dual Output differ from the HYPSOS Single Output?\u003c\/h3\u003e\n\u003cp\u003eThe HYPSOS Dual Output provides two independent DC output terminals operating at the same voltage simultaneously, compared to the Single Output's single DC terminal. Both outputs share the same 5 to 30 V adjustable voltage, meaning both connected devices must accept the same operating voltage. Combined output capacity is 60 W and 6 A across both channels, compared to the Single Output's 80 W and 6 A. The 4T Sensing Design via FPL cable is active only on the Dual Output's main output terminal, not on the secondary output. The Dual Output is ideal for simultaneously powering the OOR and WANDLA from a single unit, reducing the number of power supplies required in a full Ferrum stack.\u003c\/p\u003e\n\n\u003ch3\u003eCan both outputs of the HYPSOS Dual Output use the Ferrum Power Link cable?\u003c\/h3\u003e\n\u003cp\u003eNo. The 4T Sensing Design is only active on the main output terminal of the HYPSOS Dual Output, which connects via the proprietary Ferrum Power Link FPL cable to one Ferrum component such as the OOR or WANDLA. The secondary output terminal provides regulated DC via a standard 5.5 mm barrel connector without FPL sensing. The secondary output is still a high-quality regulated supply that benefits from the HYPSOS's hybrid linear-switching topology, but voltage is regulated at the supply output rather than at the load's internal rail. Users seeking FPL sensing on both components will require two HYPSOS Single Output units.\u003c\/p\u003e\n\n\u003ch3\u003eWhat third-party audio components are compatible with the HYPSOS?\u003c\/h3\u003e\n\u003cp\u003eThe HYPSOS is designed as a universal audiophile power supply with a 5 to 30 V continuously adjustable range, covering a broad range of DC-powered audio components beyond the Ferrum family. Compatible categories include network streamers, DACs, headphone amplifiers, phono preamplifiers, and network switches from numerous manufacturers. Ferrum maintains a compatibility list on their website. When using the HYPSOS with third-party devices via the standard 5.5 mm barrel connector, the 4T Sensing Design is not active, but the hybrid linear-switching topology, Sweet Spot Tuning, and Advanced Automation features remain fully functional. The adjustable voltage range and on-the-fly SST tuning allow optimisation of operating voltage for each connected third-party device.\u003c\/p\u003e\n\n\u003ch3\u003eWhat is Sweet Spot Tuning and how is it used?\u003c\/h3\u003e\n\u003cp\u003eSweet Spot Tuning is the HYPSOS's ability to adjust its output voltage on the fly during playback in fine increments across the full 5 to 30 V range. For Ferrum components, the recommended operating range is typically 22 to 30 V. SST allows the user to step through voltage levels while music plays and identify the specific voltage at which the connected device sounds subjectively best or measures lowest noise. For the OOR and WANDLA, the typical operating voltage is 24 V but adjusting to 25 or 26 V may yield audible differences depending on the specific unit. Sweet Spot Tuning is also useful for third-party components where the manufacturer's nominal voltage may not represent the optimal operating point.\u003c\/p\u003e\n\n\u003ch3\u003eDoes the HYPSOS Dual Output include cables in the box?\u003c\/h3\u003e\n\u003cp\u003eThe HYPSOS Dual Output ships with a high-quality DC power cable fitted to the most commonly used DC input connector. Custom cables for alternative connector sizes or lengths are available to order. The Ferrum Power Link FPL cable for 4T Sensing connection to OOR, WANDLA, or ERCO Gen 2 is a separate purchase. A Ferrum Power Splitter accessory is also available separately from Vinyl Sound Buffalo for use with HYPSOS Single Output units that require a second output using the legacy splitter approach.\u003c\/p\u003e\n\n\u003ch3\u003eWhere can I buy the Ferrum HYPSOS Dual Output in Buffalo or Western New York?\u003c\/h3\u003e\n\u003cp\u003eThe Ferrum HYPSOS Dual Output is available at Vinyl Sound, an authorised Ferrum Audio dealer in Buffalo, New York, serving customers across Western New York and the USA.

Designed as the purpose-matched power source for the Unison Research Simply Phono tube phono preamplifier, this external supply physically separates the mains transformer and rectification circuitry from the Simply Phono's audio circuit, eliminating the two primary mechanisms by which power supplies degrade phono stage performance: \u003cstrong\u003eelectromagnetic field coupling\u003c\/strong\u003e from the mains transformer into the signal path, and \u003cstrong\u003econducted noise\u003c\/strong\u003e from the AC supply into the sensitive first gain stage. In the UK and several other markets, the Simply Phono is supplied with this upgraded external power supply as standard, confirming its status as an essential companion to the phono preamplifier rather than an optional accessory.\u003c\/p\u003e\n\n\u003ch2\u003eWhy an External Power Supply Matters in Phono Preamplification\u003c\/h2\u003e\n\u003cp\u003eA phono preamplifier operates at signal levels far below those of any other component in a high-end system -- a moving-magnet cartridge produces between 2 and 5 millivolts, and a moving-coil cartridge as little as 0.2 millivolts. At these signal levels, noise contributions from the power supply that would be inaudible in a line-level amplifier become directly audible as hum, hiss, or a reduction in low-level musical detail. The Simply Phono's external power supply addresses this challenge by placing the mains transformer -- the primary source of electromagnetic field radiation in any power supply -- in a physically separate enclosure connected to the audio chassis by a low-noise DC cable. With the transformer's magnetic field confined to the external unit, the Simply Phono's four ECC83 tube stages receive a clean, regulated DC supply with minimal superimposed noise, allowing the phono stage's passive RIAA network and ionic-bias first gain stage to perform at their full capability.\u003c\/p\u003e\n\n\u003ch2\u003eEngineered for the Simply Phono Circuit\u003c\/h2\u003e\n\u003cp\u003eThe Simply Phono External Power Supply is designed specifically for the electrical requirements of the Simply Phono's four-ECC83 Class A circuit. The output voltages, current ratings, and filtering characteristics are matched to the heater and anode supply demands of the ECC83 tubes operating in the ionic bias parallel configuration of the first gain stage and the subsequent amplification stages. Using a generic or third-party power supply with the Simply Phono is not recommended, as mismatched supply voltages or insufficient filtering can degrade tube operating points and introduce noise at the most sensitive point in the signal chain. The external PSU connects to the Simply Phono via a dedicated DC umbilical, and the complete system -- phono stage plus external supply -- weighs 3 kg and occupies a compact footprint suitable for any equipment rack position.\u003c\/p\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEliminates Transformer Electromagnetic Interference:\u003c\/strong\u003e Physical separation of the mains transformer from the audio circuit removes the primary source of EMI coupling into the phono stage's first gain stage.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReduces Conducted Mains Noise:\u003c\/strong\u003e External rectification and filtering isolate AC supply noise before it reaches the ECC83 tube heater and anode circuits.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePurpose-Matched for Simply Phono:\u003c\/strong\u003e Output voltages and current ratings are specifically engineered for the Simply Phono's four-ECC83 ionic bias Class A circuit.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard Supply in Select Markets:\u003c\/strong\u003e Included as standard with the Simply Phono in the UK and other markets, confirming its role as an integral performance component rather than an optional upgrade.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompact and Discreet:\u003c\/strong\u003e Small footprint allows flexible equipment rack positioning independent of the Simply Phono chassis.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eItalian Engineering:\u003c\/strong\u003e Designed and produced within Unison Research's Treviso facility as part of the complete Simply Phono system.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\n\u003ctable\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n\u003ctd\u003eCompatible With\u003c\/td\u003e\n\u003ctd\u003eUnison Research Simply Phono phono preamplifier\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eType\u003c\/td\u003e\n\u003ctd\u003eExternal DC power supply\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eConnection\u003c\/td\u003e\n\u003ctd\u003eDedicated DC umbilical to Simply Phono\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eCombined Weight (PSU + Simply Phono)\u003c\/td\u003e\n\u003ctd\u003e3 kg\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eManufacturer\u003c\/td\u003e\n\u003ctd\u003eUnison Research \/ A.R.I.A.

In markets such as the UK, Unison Research supplies it as standard with the Simply Phono, reflecting the company's own assessment that the external PSU is the correct configuration for the phono stage. At the signal levels a phono preamplifier handles -- as low as 0.2 millivolts for moving-coil cartridges -- power supply noise that would be inaudible in a line-level component becomes directly audible. The external PSU addresses this by removing the noise source from the audio enclosure entirely.\u003c\/p\u003e\n\n\u003ch3\u003eHow does an external power supply improve phono preamplifier performance?\u003c\/h3\u003e\n\u003cp\u003eA mains transformer generates a magnetic field that radiates into surrounding components and PCB traces. In a combined chassis design, this field can induce small voltages into the phono stage's input wiring and first gain stage -- at phono signal levels, even very small induced voltages are audible as hum or a slight veiling of low-level detail. Separating the transformer into its own enclosure removes this field from the audio circuit. Additionally, the external supply's dedicated filtering removes AC ripple from the supply rail before it reaches the ECC83 tube heaters and anodes, reducing hiss and improving the noise floor of the complete system.\u003c\/p\u003e\n\n\u003ch3\u003eCan the Simply Phono Power Supply be used with other phono preamplifiers?\u003c\/h3\u003e\n\u003cp\u003eNo. The Simply Phono External Power Supply is designed specifically for the Unison Research Simply Phono preamplifier, with output voltages and current ratings matched to the Simply Phono's ECC83 tube circuit requirements.

This stands in direct contrast to Class AB designs, where the transition between the positive and negative halves of the waveform introduces a measurable distortion artifact. The Class A bias operates under a low-noise power supply of up to 60V, achieving an XLR dynamic range of 129dB A-weighted and XLR THD+N below 0.00015%. An output DC servo circuit holds the output midpoint offset within 1mV, removing any need for coupling capacitors and ensuring a flat frequency response from 20Hz to 250kHz (-3dB) with no capacitor coloration in the signal path.\u003c\/p\u003e\n\n\u003ch2\u003eTrue Dual-Mono Architecture and Precision Volume Control\u003c\/h2\u003e\n\u003cp\u003eThe MP-1 addresses channel separation with two independent custom 60W toroidal transformers wound with square copper wire, one per channel, each feeding a completely separate power regulation circuit. These transformers are paired with Mundorf M-Lytic AG series filter capacitors in the power supply stage. The fully differential transistor input stage and four independent fully balanced amplification units extend this symmetry from the power supply through to the output jacks, producing XLR crosstalk measured at -140dB. Volume attenuation is handled by a high-precision resistor array in a voltage-divider configuration, switched by high-quality relays, providing 100 steps of accurate attenuation with perfect channel consistency at every level. The XLR output delivers up to 36Vrms and the RCA output up to 18Vrms, with a 40-ohm balanced output impedance.\u003c\/p\u003e\n\n\u003ch2\u003eH-Shaped Chassis and Mechanical Isolation\u003c\/h2\u003e\n\u003cp\u003eThe MP-1 is housed in Matrix Audio's H-shaped chassis, machined from a 20mm thick CNC-aluminum central beam that forms the structural core. All internal boards are mounted directly to this beam, creating physically isolated internal cavities that prevent mechanical and electrical coupling between circuit sections. The perforated hexahedral exterior provides passive heat dissipation for the Class A output stage while expressing the Matrix Design language shared across the M Series. At 15.7kg and 430 x 349 x 106mm, the MP-1 occupies the same rack footprint as the MS-1 streamer and MA-1 power amplifier for a coherent M Series installation.\u003c\/p\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePure Class A Output Stage:\u003c\/strong\u003e High-bias current Class A amplification eliminates crossover distortion, delivering XLR THD+N below 0.00015% A-weighted and a dynamic range of 129dB A-weighted.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTrue Dual-Mono Design:\u003c\/strong\u003e Two independent custom 60W square copper wire toroidal transformers with separate power regulation circuits for left and right channels ensure that power demands on one channel cannot affect the other.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFully Balanced Architecture:\u003c\/strong\u003e A fully differential transistor input stage and four independent fully balanced amplification units provide -140dB XLR crosstalk and outstanding common-mode noise rejection from input to output.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrecision Resistor Array Volume Control:\u003c\/strong\u003e A voltage-divider system using high-precision resistors switched by quality relays delivers 100 steps of perfectly matched attenuation without a potentiometer or digital processing in the signal path.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCapacitor-Free Signal Path:\u003c\/strong\u003e An output DC servo circuit maintains the output midpoint offset within 1mV, eliminating coupling capacitors and preserving a flat frequency response to 250kHz (-3dB).\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMundorf M-Lytic AG Filter Capacitors:\u003c\/strong\u003e Premium Mundorf capacitors in the power supply stage contribute to the MP-1's smooth, detailed tonal character.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVersatile Input and Output Configuration:\u003c\/strong\u003e Three XLR balanced inputs and three RCA single-ended inputs provide comprehensive source connectivity, while two XLR balanced outputs enable bi-amping or simultaneous connection to two power amplifiers.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHigh Output Level Capability:\u003c\/strong\u003e The XLR output delivers up to 36Vrms and the RCA output up to 18Vrms, with a 40-ohm balanced output impedance, ensuring compatibility with any power amplifier regardless of input sensitivity.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eH-Shaped CNC Chassis:\u003c\/strong\u003e A 20mm thick central aluminum beam forms isolated internal cavities for each circuit section, providing mechanical rigidity and shielding against external vibration and inter-circuit interference.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTrigger In \/ Out:\u003c\/strong\u003e DC trigger ports enable system-wide power sequencing when paired with the Matrix Audio MA-1 power amplifier and MS-1 or MS-1c streamers.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\n\u003ctable\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n\u003ctd\u003eProduct Type\u003c\/td\u003e\n\u003ctd\u003ePure Class A Stereo Preamplifier\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eAmplifier Class\u003c\/td\u003e\n\u003ctd\u003ePure Class A\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eArchitecture\u003c\/td\u003e\n\u003ctd\u003eTrue dual-mono, fully balanced differential\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eXLR Input Impedance\u003c\/td\u003e\n\u003ctd\u003e40k ohm\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eRCA Input Impedance\u003c\/td\u003e\n\u003ctd\u003e20k ohm\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eXLR Max Input Level\u003c\/td\u003e\n\u003ctd\u003e9Vrms\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eRCA Max Input Level\u003c\/td\u003e\n\u003ctd\u003e4.5Vrms\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eXLR Output Impedance\u003c\/td\u003e\n\u003ctd\u003e40 ohm\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eRCA Output Impedance\u003c\/td\u003e\n\u003ctd\u003e20 ohm\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eXLR Max Output Level\u003c\/td\u003e\n\u003ctd\u003e36Vrms\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eRCA Max Output Level\u003c\/td\u003e\n\u003ctd\u003e18Vrms\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eGain\u003c\/td\u003e\n\u003ctd\u003e+12dB\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eVolume Steps\u003c\/td\u003e\n\u003ctd\u003e100\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eFrequency Response\u003c\/td\u003e\n\u003ctd\u003e20Hz -

It measures XLR THD+N below 0.00015% A-weighted, XLR dynamic range of 129dB A-weighted, and XLR crosstalk at -140dB. It forms part of the Matrix Audio M Series flagship system alongside the MS-1 streamer and MA-1 power amplifier, and is available at Vinyl Sound in Buffalo, New York, USA.\u003c\/p\u003e\n\n\u003ch3\u003eHow does the Matrix Audio MP-1 compare to the Pass Labs XP-12 or Parasound JC 2 BP?\u003c\/h3\u003e\n\u003cp\u003eThe Matrix Audio MP-1 competes directly with high-end Class A preamplifiers such as the Pass Labs XP-12 and Parasound JC 2 BP. The Pass Labs XP-12 also uses a pure Class A topology but relies on a single-ended power supply design and rotary volume control. The Parasound JC 2 BP is a fully balanced design with a higher input count but uses a conventional potentiometer-based volume control. The MP-1 differentiates through its true dual-mono independent transformer power supply, precision resistor array voltage-divider volume control with relay switching, 36Vrms maximum balanced output level, Mundorf M-Lytic AG filter capacitors, and the integrated trigger system designed for seamless operation within the M Series ecosystem.\u003c\/p\u003e\n\n\u003ch3\u003eCan the Matrix Audio MP-1 drive a power amplifier directly?\u003c\/h3\u003e\n\u003cp\u003eYes. The MP-1 drives any power amplifier directly through its XLR balanced outputs, which deliver up to 36Vrms with a 40-ohm output impedance and +12dB of gain. The 100-step resistor array volume control handles all attenuation, making a secondary preamplifier or buffer unnecessary. The dual XLR outputs also allow bi-amping a single pair of loudspeakers or simultaneously driving two separate power amplifiers.\u003c\/p\u003e\n\n\u003ch3\u003eWhat is pure Class A amplification and why does it matter in a preamplifier?\u003c\/h3\u003e\n\u003cp\u003ePure Class A amplification keeps the output transistors continuously conducting throughout the full audio waveform cycle, so the signal never crosses through a zero-current transition point. In Class AB designs, a brief crossover distortion artifact occurs each time the signal switches between the positive and negative halves of the waveform. In a preamplifier, where the signal is low-level and extremely sensitive to coloration, eliminating crossover distortion results in a more accurate, liquid, and tonally natural rendering of fine musical detail and texture.\u003c\/p\u003e\n\n\u003ch3\u003eWhat does the resistor array volume control in the MP-1 do differently from a standard potentiometer?\u003c\/h3\u003e\n\u003cp\u003eA conventional potentiometer volume control uses a continuous resistive track and a wiper contact that introduces channel imbalance at low volume settings and adds resistance into the audio signal path at all times. The MP-1's resistor array voltage-divider volume control uses a fixed matrix of high-precision resistors switched in and out of the signal path by quality relays in 100 discrete steps. At every attenuation level the signal passes through only a precisely defined resistive network, preserving channel consistency, soundstage integrity, and signal transparency in a way that potentiometer designs cannot match.\u003c\/p\u003e\n\n\u003ch3\u003eDoes the Matrix Audio MP-1 work with the MS-1 and MS-1c streamers?\u003c\/h3\u003e\n\u003cp\u003eYes. The MP-1 is designed as the control center of the Matrix Audio M Series and integrates directly with the MS-1, MS-1 PRE, and MS-1c music streamers via balanced XLR interconnection. The shared trigger system allows the MP-1 to power up and down in sequence with the MS-1 or MS-1c and the MA-1 power amplifier. The MP-1 accepts up to six sources across its three XLR and three RCA inputs, making it the switching hub for a complete M Series or mixed-source system.\u003c\/p\u003e\n\n\u003ch3\u003eWhere can I buy the Matrix Audio MP-1 in Buffalo, NY or the USA?\u003c\/h3\u003e\n\u003cp\u003eThe Matrix Audio MP-1 is available at Vinyl Sound, located in Buffalo, New York, USA.

Configurable for Stereo, bridged Mono, or dual Mono operation, the MA-1 has been reviewed by Positive Feedback alongside the Matrix Audio MP-1 preamplifier as part of the complete M Series flagship system.\u003c\/p\u003e\n\n\u003ch2\u003eOutput Stage: Ten ONSEMI Transistors Per Channel in Push-Pull\u003c\/h2\u003e\n\u003cp\u003eThe MA-1's output stage deploys ten ONSEMI high-power transistors per channel in a parallel push-pull configuration operated at high bias current. Applying ten devices in parallel dramatically lowers the effective output impedance, contributing to the measured damping factor of 350 at 8 ohms and 1kHz. High damping factor means the amplifier exerts precise control over speaker cone movement, translating directly into tighter bass definition and faster transient response. The high-bias operating point minimizes crossover distortion artifacts, preserving textural detail across all dynamic levels. Gain is selectable between +24dB and +30dB, allowing the MA-1 to be accurately matched to preamplifiers of different output levels without compromising the gain structure of the system.\u003c\/p\u003e\n\n\u003ch2\u003eDual-Mono 1250VA Power Supply and 190,000µF Capacitor Bank\u003c\/h2\u003e\n\u003cp\u003eThe MA-1's power supply is built around two independent toroidal transformers wound with square copper wire, each dedicated to one channel, providing a combined 1250VA of capacity. Square copper wire windings deliver lower resistance and higher current capacity than conventional round wire, improving transient response and low-frequency authority. The transformer outputs feed a capacitor bank totaling 190,000µF, composed of 14 parallel-connected 6,800µF capacitors per channel. Distributing the capacitance across multiple smaller capacitors reduces equivalent series resistance compared to a single large capacitor of equivalent value, enabling instantaneous response to large current demands at musical peaks without voltage sag. The main supply rail operates at plus or minus 80V, and total static power consumption at idle reaches 250 to 350W, reflecting the high-bias state of the output stage.\u003c\/p\u003e\n\n\u003ch2\u003eThree Operating Modes: Stereo, Dual Mono, and Bridged\u003c\/h2\u003e\n\u003cp\u003eThe MA-1 operates in three distinct configurations. In Stereo mode it delivers 250W into 8 ohms and 450W into 4 ohms per channel, stable down to 2 ohms. In dual Mono mode, two MA-1 units each handle a single channel independently, providing a dedicated power supply, output stage, and chassis for each loudspeaker. In bridged Mono mode, two MA-1 units combine to deliver 500W into 8 ohms or 900W into 4 ohms from a single bridged output. Input sensitivity adjusts from 1.48Vrms in Stereo and Mono to 1.0Vrms in Bridged mode to maintain optimal gain structure across all three configurations.\u003c\/p\u003e\n\n\u003ch2\u003eH-Shaped Chassis and Intelligent Thermal Management\u003c\/h2\u003e\n\u003cp\u003eThe MA-1 uses an H-shaped chassis machined from a 20mm thick CNC-aluminum central beam to which all components are mounted, creating isolated internal cavities that prevent electromagnetic coupling between circuit sections. The left and right channel circuits are arranged symmetrically on either side of the beam, contributing to the measured -125dB crosstalk figure. Thermal management is handled by two temperature sensors that trigger a 7.4-inch fan inside an isolated duct when a preset threshold is exceeded, keeping airflow away from electronic components and maintaining near-silent operation at normal listening levels. At 42.4kg and 430 x 518 x 201mm, the MA-1 shares the same rack width as the MP-1 and MS-1 for a coherent M Series installation.\u003c\/p\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003e250W Per Channel into 8 Ohms (Stereo):\u003c\/strong\u003e Ten ONSEMI transistors per channel in parallel push-pull at high bias current deliver 250W into 8 ohms, 450W into 4 ohms, and stability down to 2-ohm loads in Stereo and Mono modes.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e900W Bridged Mono into 4 Ohms:\u003c\/strong\u003e Two MA-1 units operate in bridged Mono mode to deliver up to 900W into 4 ohms, providing reference-level power for the most demanding loudspeakers.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThree Configurable Operating Modes:\u003c\/strong\u003e Stereo, dual Mono, and bridged Mono modes offer three distinct amplifier configurations from a single chassis, adaptable to any system topology.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDual-Mono 1250VA Power Supply:\u003c\/strong\u003e Two independent square copper wire toroidal transformers, one per channel, provide a combined 1250VA with complete channel isolation at the power supply level.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e190,000µF Capacitor Bank:\u003c\/strong\u003e 14 parallel-connected 6,800µF capacitors per channel form a low-ESR energy reservoir that responds instantaneously to dynamic current demands without compression.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDamping Factor of 350 at 8 Ohms:\u003c\/strong\u003e The low output impedance from ten parallel output transistors gives the MA-1 precise control over speaker drivers, delivering tight bass and fast transients.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSelectable Gain (+24dB \/ +30dB):\u003c\/strong\u003e Two gain settings allow accurate level matching with any preamplifier output, preserving optimal gain structure across the full system.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIntelligent Silent Cooling:\u003c\/strong\u003e Two heatsink temperature sensors trigger a 7.4-inch fan in an isolated duct when a thermal threshold is reached, keeping fan noise effectively inaudible during normal listening.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eH-Shaped CNC Chassis:\u003c\/strong\u003e A 20mm thick central aluminum beam provides mechanically isolated internal cavities for each circuit module, with left and right channels arranged symmetrically for minimum inter-channel interference.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTrigger In \/ Out:\u003c\/strong\u003e DC trigger ports enable system-wide power sequencing when integrated with the Matrix Audio MP-1 preamplifier and MS-1 or MS-1c streamers.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\n\u003ctable\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n\u003ctd\u003eProduct Type\u003c\/td\u003e\n\u003ctd\u003eClass AB Stereo Power Amplifier\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eOutput Stage\u003c\/td\u003e\n\u003ctd\u003e10x ONSEMI high-power transistors per channel, parallel push-pull\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eStereo \/ Mono Power (8 ohm)\u003c\/td\u003e\n\u003ctd\u003e2x 250W RMS\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eStereo \/ Mono Power (4 ohm)\u003c\/td\u003e\n\u003ctd\u003e2x 450W RMS\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eBridged Mono Power (8 ohm)\u003c\/td\u003e\n\u003ctd\u003e1x 500W RMS\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eBridged Mono Power (4 ohm)\u003c\/td\u003e\n\u003ctd\u003e1x 900W RMS (music signal)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eOperating Modes\u003c\/td\u003e\n\u003ctd\u003eStereo, Dual Mono, Bridged Mono\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eXLR Input Impedance\u003c\/td\u003e\n\u003ctd\u003e40k ohm\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eRCA Input Impedance\u003c\/td\u003e\n\u003ctd\u003e20k ohm\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eInput Sensitivity (Stereo \/ Mono)\u003c\/td\u003e\n\u003ctd\u003e1.48Vrms\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eInput Sensitivity (Bridged)\u003c\/td\u003e\n\u003ctd\u003e1.0Vrms\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eGain\u003c\/td\u003e\n\u003ctd\u003e+24dB \/ +30dB (selectable)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eFrequency Response\u003c\/td\u003e\n\u003ctd\u003e20Hz -

It delivers 250W per channel into 8 ohms in Stereo mode, scaling to 900W into 4 ohms in bridged Mono mode, with selectable +24dB and +30dB gain and a measured damping factor of 350 at 8 ohms. It forms the power amplification anchor of the Matrix Audio M Series alongside the MP-1 preamplifier and MS-1 or MS-1c streamers, and is available at Vinyl Sound in Buffalo, New York, USA.\u003c\/p\u003e\n\n\u003ch3\u003eHow does the Matrix Audio MA-1 compare to the Pass Labs XA60.8 or Parasound JC 5?\u003c\/h3\u003e\n\u003cp\u003eThe Matrix Audio MA-1 competes directly with high-power stereo amplifiers such as the Pass Labs XA60.8 and Parasound JC 5. The Pass Labs XA60.8 operates in pure Class A up to 60W before transitioning to Class AB, prioritizing tonal purity at lower output levels with a lower peak power ceiling. The Parasound JC 5 is a fully balanced Class AB design delivering 400W into 4 ohms. The MA-1 differentiates with its ten-transistor-per-channel parallel output stage, true dual-mono 1250VA power supply with independent transformers per channel, three configurable operating modes including bridged Mono at 900W into 4 ohms, and an integrated trigger and gain-switching system designed for seamless M Series operation.\u003c\/p\u003e\n\n\u003ch3\u003eCan two Matrix Audio MA-1 amplifiers be used in bridged Mono mode?\u003c\/h3\u003e\n\u003cp\u003eYes. Two MA-1 units operating in bridged Mono mode each deliver a single channel at up to 500W into 8 ohms or 900W into 4 ohms. Each amplifier handles one loudspeaker with the full combined output of both internal channels, making it appropriate for power-hungry loudspeakers or large listening rooms where extreme output power and authority are required. The minimum speaker impedance in bridged Mono mode is 4 ohms.\u003c\/p\u003e\n\n\u003ch3\u003eWhat is dual Mono mode on the MA-1 and how does it differ from Stereo mode?\u003c\/h3\u003e\n\u003cp\u003eIn dual Mono mode, two MA-1 amplifiers are used with one unit dedicated entirely to the left channel and the other to the right. Each amplifier operates as a single-channel device with its complete power supply, output stage, and chassis devoted to one loudspeaker. This eliminates shared power supply interaction between channels and reduces the noise floor per channel compared to standard Stereo mode. Dual Mono mode is well suited to loudspeakers that support bi-wiring or bi-amping, and to audiophiles seeking maximum channel separation and dynamic headroom in a reference system.\u003c\/p\u003e\n\n\u003ch3\u003eWhat loudspeakers are compatible with the Matrix Audio MA-1?\u003c\/h3\u003e\n\u003cp\u003eThe MA-1 is compatible with loudspeakers presenting a load of 2 to 16 ohms in Stereo and Mono modes, covering the full range of modern passive loudspeaker designs including low-impedance floorstanders from brands such as Wilson Audio, Magico, Focal, and Bowers and Wilkins. In bridged Mono mode the minimum supported impedance rises to 4 ohms. The MA-1's damping factor of 350 and its high current reserve from the 190,000µF capacitor bank make it particularly effective at controlling woofer drivers in large bass-reflex and transmission-line loudspeaker systems.\u003c\/p\u003e\n\n\u003ch3\u003eHow does the MA-1's intelligent cooling system work?\u003c\/h3\u003e\n\u003cp\u003eThe MA-1 uses two temperature sensors that continuously monitor the main heatsink surface. Under normal listening conditions the amplifier operates passively with no fan activity. When the heatsink temperature exceeds a preset threshold, a 7.4-inch fan activates inside an isolated internal duct that directs airflow away from circuit boards and electronic components. This ducted design prevents dust accumulation on sensitive parts and keeps fan noise effectively inaudible during typical listening sessions. Fan speed adjusts dynamically in proportion to the measured thermal load, stepping back down and stopping as the heatsink cools.\u003c\/p\u003e\n\n\u003ch3\u003eWhat gain setting should I use when pairing the MA-1 with the Matrix Audio MP-1 preamplifier?\u003c\/h3\u003e\n\u003cp\u003eThe appropriate gain setting depends on the sensitivity of the loudspeakers and the output level of the MP-1. The MP-1 delivers up to 36Vrms from its XLR balanced output with +12dB of gain, which is a very high output level. In most systems with moderately sensitive loudspeakers, the MA-1's +24dB gain setting will provide ample output while keeping the volume control in a precise and usable range. The +30dB setting is better suited to low-sensitivity loudspeakers or situations where the source level is inherently low. Vinyl Sound Buffalo can advise on the correct gain configuration for a specific system.\u003c\/p\u003e\n\n\u003ch3\u003eWhere can I buy the Matrix Audio MA-1 in Buffalo, NY or the USA?\u003c\/h3\u003e\n\u003cp\u003eThe Matrix Audio MA-1 is available at Vinyl Sound, located in Buffalo, New York, USA.
