EverSolo AMP-F10 Stereo Power Amplifier at Vinyl Sound Buffalo, NY USA

The AMP-F10 is the flagship stereo power amplifier from EverSolo (Shenzhen, China), available at Vinyl Sound in Buffalo, NY, USA. EverSolo's first dedicated power amplifier, the AMP-F10 delivers 200 W per channel into 8 ohms and 320 W per channel into 4 ohms in Class AB operation, rising to 950 W into 4 ohms in bridged mono mode. Built around five pairs of precision-matched MOSFET output transistors per channel, a 1,000 W dual-channel independent linear power supply, and an innovative DC filtering circuit, the AMP-F10 achieves a THD+N of 0.008%, SNR of 113 dB, and a damping factor exceeding 600. Reviewed by Stereophile in August 2025 and awarded the Essential Audition Award by Pursuit Perfect System, the AMP-F10 is designed as a natural visual and sonic complement to the EverSolo DMP-A10 and is available to audiophiles across Western New York at Vinyl Sound in Buffalo.

Class AB Topology, MOSFET Output Stage, and Linear Power Supply

The AMP-F10 operates in Class AB with a Class A bias point, ensuring the first watts of output are handled in pure Class A for warmth and linearity before the circuit transitions to Class AB for higher power demands. Each channel is driven by five pairs of precision-matched high-current MOSFET output transistors configured in parallel, a topology that distributes current evenly across the output devices to reduce non-linearity and minimize thermal stress. The output stage is supported by a 1,000 W dual-channel independent linear power supply, with each channel drawing from its own dedicated supply rail to prevent cross-channel interference and to guarantee stable, high-current delivery under sustained dynamic loads. A rear-panel gain switch allows selection between 23 dB and 29 dB of voltage gain, enabling the AMP-F10 to be optimized for preamplifiers with either standard or low output levels. The full-width 430 mm aluminum chassis doubles as a passive heatsink through large sculpted heatsink fins on both sides, requiring no fan or active cooling.

DC Filtering Circuit, Dual Differential Amplifiers, and Bridge Mode

EverSolo's innovative DC filtering circuit sits between the mains AC supply and the audio circuit, intercepting low-frequency DC offset from the power line before it reaches the toroidal transformer. DC contamination on the AC supply is a known cause of transformer mechanical hum and elevated noise floors in power amplifiers; the AMP-F10's filtering stage removes this interference at the source rather than relying on downstream rejection. The input stage uses advanced dual differential amplifiers optimized for low-level signals, with a fully symmetrical circuit topology and controlled negative feedback to minimize distortion while preserving the linearity of the voltage gain stage. Common-mode noise from the power supply and environment is suppressed by the balanced circuit geometry, keeping the noise floor low across all listening levels. In bridge mode, a single AMP-F10 functions as a monoblock amplifier, delivering 650 W into 8 ohms and 950 W into 4 ohms from a single chassis. Two AMP-F10 units can be run in bridged configuration for a high-power mono system.

Connections, Controls, and VU Meters

The AMP-F10 accepts one balanced XLR input and one single-ended RCA input, with a rear-panel switch selecting which input is active at any time. Both inputs present an impedance of 10 kohms to the driving source. A 12V trigger input and output enable automatic power sequencing with compatible preamplifiers and source components, including the EverSolo DMP-A10. The front panel features two illuminated analog VU meters calibrated to display power output on a logarithmic scale from 3.4 mW to 480 W, calculated into a 4-ohm load, providing a real-time visual reference of dynamic output levels. Speaker binding posts are located on the rear panel. A standby switch and bridge mode selector are also provided at the rear, with no front-panel switches to interrupt the clean aesthetic of the fascia.

Frequently Asked Questions

What is the EverSolo AMP-F10?

The EverSolo AMP-F10 is a stereo Class AB power amplifier delivering 200 W per channel into 8 ohms, 320 W per channel into 4 ohms, and up to 950 W in bridged mono mode into 4 ohms. It uses five pairs of precision-matched MOSFET output transistors per channel, a 1,000 W dual-channel independent linear power supply, and an innovative DC filtering circuit to remove mains DC contamination before it reaches the audio circuit. The AMP-F10 is EverSolo's first dedicated power amplifier and is designed as a matched visual and sonic partner to the EverSolo DMP-A10 streaming DAC/preamp.

How does the EverSolo AMP-F10 compare to the NAD C 298 and Rotel RB-1582 MkII?

The AMP-F10 occupies a similar power class to the NAD C 298 and Rotel RB-1582 MkII but approaches the design differently. The NAD C 298 uses Purifi Eigentakt Class D modules rated at 185 W into 8 ohms, prioritizing a very low noise floor and high efficiency. The Rotel RB-1582 MkII is a traditional Class AB design rated at 200 W into 8 ohms with a toroidal transformer and discrete output stage. The AMP-F10 matches or exceeds both on rated power, adds a 2-ohm output rating of 450 W per channel, includes bridged mono capability reaching 950 W into 4 ohms, and incorporates the DC filtering circuit and dual differential input stage not found in the RB-1582 MkII. The AMP-F10's MOSFET output stage and Class A bias point align it more closely with the Rotel's analog character than the NAD's Class D efficiency-focused topology.

Can the EverSolo AMP-F10 be used as a monoblock amplifier?

The AMP-F10 supports bridge mono operation, converting the stereo amplifier into a single high-power monoblock channel. In bridge mode, a single AMP-F10 delivers 650 W into 8 ohms or 950 W into 4 ohms, with a bridge mode selector switch on the rear panel. Two AMP-F10 units are required to build a stereo monoblock system, one per channel. Bridge mode is best suited to power-hungry loudspeakers in larger rooms or for listeners who require the maximum dynamic headroom from the AMP-F10 platform.

What is the DC filtering circuit in the AMP-F10 and why does it matter?

The DC filtering circuit sits between the household AC mains supply and the AMP-F10's toroidal transformer, intercepting low-frequency DC offset before it reaches the transformer core. DC on the AC supply is a widespread issue caused by asymmetric AC grid loading and is a primary cause of audible transformer mechanical hum in power amplifiers. By filtering out DC at the input stage, the AMP-F10 eliminates a common source of background noise and transformer vibration that affects many high-power amplifiers operating on real-world mains supplies, resulting in a quieter noise floor and improved performance of the downstream audio circuitry.

What preamplifiers and sources pair well with the EverSolo AMP-F10?

The AMP-F10 accepts both balanced XLR and single-ended RCA inputs at 10 kohms, making it compatible with virtually any preamplifier or integrated streaming DAC with a variable output. Its natural system partner is the EverSolo DMP-A10, which provides a 4.2 V balanced XLR output and 12V trigger output that interfaces directly with the AMP-F10's trigger input for automated power sequencing. The AMP-F10 also pairs well with other preamplifiers available at Vinyl Sound in Buffalo, including the NAD Masters M12 and Audiolab 9000CDT-based systems, and its gain switch provides flexibility when matching sources with lower output voltages.

What speakers work best with the EverSolo AMP-F10?

The AMP-F10's damping factor exceeding 600 gives it strong low-frequency control over a wide range of speaker impedances, including challenging 4-ohm and 2-ohm loads. With 320 W available at 4 ohms, it drives demanding loudspeakers from brands including Klipsch, PSB, DALI, and Wharfedale with significant headroom. Stereophile's review noted the AMP-F10 is particularly effective at giving standmount and bookshelf speakers added bass weight and presence, making it an effective match for high-quality compact speakers that benefit from a high-current amplifier. The 2-ohm power rating of 450 W per channel also makes it suitable for electrostatic and ribbon hybrid designs that present low or variable impedance loads.
