Matrix Audio MS-1 PRE Music Streamer at Vinyl Sound Buffalo, NY USA

The MS-1 PRE is a flagship music streamer, DAC, and integrated preamplifier from Matrix Audio (Xi'an, Shaanxi, China), available at Vinyl Sound in Buffalo, New York, USA. Built around dual AKM AK4499EX + AK4191 DAC chipsets in a fully independent dual-mono configuration, the MS-1 PRE supports native high-resolution audio up to DSD512 and PCM 768kHz via USB-B and I2S LVDS inputs. Its integrated resistor array volume control preamplifier delivers up to 16Vrms balanced output with a measured THD+N of less than 0.000068% at 1kHz, enabling direct connection to power amplifiers or active loudspeakers without an intermediate preamplifier. Reviewed by Hi-Fi News in February 2025, the MS-1 PRE is the flagship centerpiece of the Matrix Audio M Series, sitting alongside the MP-1 Class A preamplifier and MA-1 Class AB power amplifier.

Dual AKM Flagship DAC Architecture

At the heart of the MS-1 PRE are two complete sets of AKM AK4191 and AK4499EX DAC chipsets, each operating in mono mode with independent left and right channel PCB modules mounted on either side of the internal H-frame chassis. This dual-mono architecture eliminates crosstalk between channels, with the balanced XLR line output measuring greater than -150dB of channel separation. A DPLL high-precision reclocking circuit with a reference clock jitter floor of 45 femtoseconds minimizes jitter at the input stage, while an optional 10MHz external clock input allows synchronization with a dedicated master clock for reference-level timing accuracy. The MS-1 PRE supports hardware asynchronous upsampling and PCM-to-DSD conversion, giving the listener direct control over the digital signal path from the 220mm front-panel touchscreen or the MA Remote App.

Integrated Preamplifier and Analog Inputs

Unlike the standard MS-1, the PRE variant adds a fully featured multi-stage operational amplifier preamplifier with precision resistor array volume control. The balanced XLR pre-output delivers 0 to 16Vrms variable with +10dB of gain and an output impedance of just 40 ohms, measured at an SNR of 131dB A-weighted. The fixed XLR line output provides a stable 5Vrms for integration into systems where a separate preamplifier handles volume control. Analog inputs include a balanced XLR input with an SNR of 118dB and THD+N below 0.00026%, a single-ended RCA input, and a phono input with MM and MC compatibility. The MM stage provides +45dB of gain at 47k ohm loading and the MC stage +65dB of gain at 100 ohm loading, making the MS-1 PRE a complete analog and digital hub for a high-end listening system.

Streaming, Connectivity, and Expandability

The MS-1 PRE streams natively over a Gigabit Ethernet LAN port or an SFP fiber optic network port for galvanically isolated network connectivity, eliminating ground noise introduced by upstream network infrastructure. Wireless protocols include AirPlay 2, DLNA, UPnP, Spotify Connect, and Tidal Connect, alongside high-resolution services such as Tidal and Qobuz. Local playback is handled from USB-A storage, a user-installable internal M.2 NVMe SSD slot, and NAS drives over the network. Digital inputs span USB-B, two coaxial, one optical Toslink, and an I2S LVDS interface via HDMI, covering every digital source from CD transports to computers. The MA Player software environment, controllable via the 220mm front-panel touchscreen or the MA Remote App for iOS and Android, provides a purpose-built interface for audiophile playback across all sources.

Frequently Asked Questions

What is the Matrix Audio MS-1 PRE?

The Matrix Audio MS-1 PRE is a flagship music streamer, DAC, and integrated preamplifier from Matrix Audio (Xi'an, China), built around dual AKM AK4499EX and AK4191 DAC chipsets in a fully independent dual-mono channel configuration. It supports native DSD512 and PCM 768kHz playback, outputs up to 16Vrms balanced from its resistor array preamplifier stage, and streams over both Gigabit Ethernet and SFP fiber optic network inputs. It is the centerpiece of the Matrix Audio M Series flagship system, designed to drive a power amplifier or active speakers directly without an external preamplifier.

How does the Matrix Audio MS-1 PRE compare to the Lumin X1 or Aurender N30SA?

The Matrix Audio MS-1 PRE competes at the flagship tier against streamers such as the Lumin X1 and Aurender N30SA. The Lumin X1 uses ESS Sabre DAC technology and outputs a fixed-level signal without a variable preamplifier stage. The Aurender N30SA operates as a transport-only server, requiring a separate external DAC and preamplifier for complete system integration. The MS-1 PRE integrates dual AKM AK4499EX DAC chips, a fully featured resistor array preamplifier with variable output up to 16Vrms, a built-in phono stage supporting both MM and MC cartridges, an SFP fiber optic network input, and an internal NVMe SSD slot, delivering a broader all-in-one feature set at the flagship price point.

Can the Matrix Audio MS-1 PRE connect directly to a power amplifier?

Yes. The MS-1 PRE connects directly to a power amplifier via its variable balanced XLR pre-output, which delivers up to 16Vrms with +10dB of gain and a 40-ohm output impedance. This output level is sufficient to drive virtually any power amplifier to full output without an intermediate preamplifier. A variable RCA single-ended pre-output delivering up to 8Vrms is also available for amplifiers without balanced inputs.

What is the SFP fiber optic network port on the MS-1 PRE?

The SFP port on the Matrix Audio MS-1 PRE is a fiber optic network interface that accepts a standard SFP transceiver module, replacing the copper Ethernet connection with an optical one. This eliminates galvanic coupling between the upstream router or network switch and the streamer, removing a common source of ground-loop noise and electrical interference in high-end audio systems. It operates at 10/100/1000 Mbps and can be used alongside or in place of the standard RJ45 Ethernet port.

Does the Matrix Audio MS-1 PRE support vinyl playback?

Yes. The MS-1 PRE includes an onboard phono input with separate MM and MC cartridge stages. The MM stage offers +45dB of gain with a 47k ohm input impedance, while the MC stage provides +65dB of gain with 100 ohm loading. A turntable can be connected directly to the MS-1 PRE without a separate phono preamplifier, integrating analog vinyl playback into the same volume control and output stage as all other sources in the system.

What is the difference between the Matrix Audio MS-1 and the MS-1 PRE?

The Matrix Audio MS-1 PRE adds an integrated multi-stage resistor array preamplifier to the standard MS-1 music streamer. This preamplifier provides +10dB of gain, a variable balanced XLR output of up to 16Vrms, and a variable RCA output of up to 8Vrms, enabling direct connection to power amplifiers and active speakers. The standard MS-1 outputs only a fixed-level signal and lacks the volume control, gain stage, and phono input of the PRE variant. Both units share the same dual AKM DAC chipset, chassis construction, and digital input configuration.

Is the Matrix Audio MS-1 PRE compatible with Roon?

The Matrix Audio MS-1 PRE operates on Matrix Audio's proprietary MA Player software platform. For current Roon Ready certification status, prospective buyers should verify directly with Vinyl Sound Buffalo or consult the Roon Labs device database, as certification for new flagship components can be added after initial product launch.
