Eversolo AMP-F8 Power Amplifier

The Eversolo AMP-F8 is a dedicated stereo power amplifier operating in Class AB with Class A bias, delivering 180 watts per channel into 8 ohms, 280 watts per channel into 4 ohms, and 500 watts bridged into 8 ohms in monoblock configuration. Three matched MOSFET pairs per channel drive the output stage, a toroidal transformer feeds the linear power supply, and a damping factor above 400 gives the amplifier firm, precise control over woofer motion at any listening level. Total harmonic distortion is held to 0.003 percent. Signal-to-noise ratio is 115 dB A-weighted. Twin analog VU meters with switchable backlight span the front panel.

The AMP-F8 is Eversolo's dedicated power amplifier positioned to partner with the DMP-A8 or DMP-A8 Master Edition Gen 2 streaming DAC preamplifier source components, or any preamplifier with XLR or RCA outputs. It is priced at $1,800, below the AMP-F10 ($2,480), and represents the most direct path to a complete Eversolo two-box high-performance system.

Class AB With Class A Bias — Real-World Listening Optimized

At low and moderate signal levels, the AMP-F8 operates in Class A, where the output devices conduct continuously and crossover distortion does not arise as a mechanism. As dynamic demand increases, the amplifier transitions into Class AB, managing thermal load and current draw proportionally to what the music actually requires. This is a deliberate engineering choice that concentrates Class A operation at the signal levels where most real listening happens, avoiding the full-time heat output and power consumption of a pure Class A design without sacrificing the sonic character Class A delivers at ordinary volumes.

Matched MOSFET Output Stage — Three Pairs Per Channel

Each channel uses three precision-matched MOSFET pairs in the output stage. MOSFET devices are chosen over bipolar transistors for their smoother, more gradual gain characteristics and their natural resistance to thermal runaway, which contributes to long-term stability and consistent performance over extended listening sessions. Matching the devices to close tolerances ensures the left and right channels behave identically, contributing to the amplifier's measured crosstalk of 95 dB at 180 watts into 8 ohms and supporting the precise stereo imaging the AMP-F8 is capable of delivering.

Toroidal Transformer and Linear Power Supply

The AMP-F8's linear power supply is built around a toroidal transformer rated for 1,200 watts maximum draw. The toroidal geometry produces a lower external magnetic field than conventional EI-core transformers, reducing electromagnetic interference with the amplifier's sensitive signal-carrying circuits. A linear supply does not introduce the switching noise of a switch-mode design, and the supply reserve the toroidal provides ensures the amplifier can meet sudden current demands from difficult loads or large transients without audible compression.

Dual Analog VU Meters Calibrated in Watts

Two analog needle-type VU meters span the front panel, calibrated in watts to show actual output power rather than relative signal level. The backlight is independently switchable from the rear panel for dark listening environments. A dual-color LED ring around the front-panel standby button reports operating state at a glance: white for active, orange for standby, and alternating for protection mode. The front panel is otherwise minimal, with the meters doing the visual work.

Flexible Gain, Inputs, and Trigger Standby

Each channel accepts both balanced XLR and unbalanced RCA input, selected by an independent rear-panel input mode switch per channel. This allows the left and right channels to run from different input types if the source requires it, which is unusual and practically useful in hybrid system configurations. A rear gain switch selects between 23 dB and 29 dB sensitivity, matching the amplifier to sources of differing output voltage and speakers of differing sensitivity. A 5 to 12 volt trigger input and output connects the AMP-F8 into a system where components power on and off in sequence, and signal-sensing standby mode powers the amplifier down after twenty minutes of silence and restores it automatically when signal returns.

Bridged Mono Operation — 500 Watts Into 8 Ohms

A rear-panel switch reconfigures the AMP-F8 for bridged mono operation, raising output to 500 watts into 8 ohms. Two AMP-F8 units used as a monoblock pair provide 500 watts per channel for demanding speakers or large rooms. Bridged mode is rated for 8 ohm loads only — 4 ohm loads in bridged mode are not supported. Eversolo specifies powering the amplifier down and disconnecting the speakers before changing the mode switch, and confirming that the speaker's impedance and power handling are appropriate for the higher bridged output before use.

AMP-F8 vs AMP-F10 — The Eversolo Power Amplifier Lineup

The AMP-F8 ($1,800) and AMP-F10 ($2,480) are the two stereo power amplifiers in the current Eversolo lineup. The AMP-F8 delivers 180 watts into 8 ohms and 500 watts bridged; the AMP-F10 is the higher-output model. For listeners building a system around an Eversolo streaming DAC source and a speaker pair of 87 dB or above sensitivity in a typical room, the AMP-F8's 180 watts provides genuine headroom and pairs naturally with the DMP-A8 or DMP-A8 Master Edition Gen 2. For listeners who need more output, larger rooms, or are driving more demanding loads, the AMP-F10 is the appropriate step up.

Frequently Asked Questions — Eversolo AMP-F8

What is the Eversolo AMP-F8 and what is it designed for?
The AMP-F8 is a Class AB stereo power amplifier with Class A bias rated at 180W into 8Ω and 280W into 4Ω, designed to partner with a streaming DAC preamplifier source such as the Eversolo DMP-A8 or any balanced or unbalanced preamplifier output in a high-performance two-channel system. It is the lower-output model in the Eversolo power amplifier lineup at $1,800, below the AMP-F10 at $2,480.

What does Class AB with Class A bias mean on the AMP-F8?
At low and moderate listening levels the output devices conduct continuously in Class A, eliminating crossover distortion at the signal levels where most listening occurs. As dynamic demand rises the amplifier transitions to Class AB, keeping power consumption and heat proportional to actual musical output rather than running at full Class A current draw at all times.

What output devices does the AMP-F8 use?
Three matched MOSFET pairs per channel drive the output stage. MOSFET devices offer smooth, gradual gain characteristics and natural thermal stability, and precision-matching the pairs to close tolerances ensures identical behavior between left and right channels for accurate stereo imaging and low crosstalk, measured at 95 dB at full rated power.

Does the AMP-F8 support bridged mono operation?
Yes, a rear-panel switch reconfigures the AMP-F8 for bridged mono, raising output to 500W into 8Ω. Bridged operation is rated for 8 ohm loads only; 4 ohm loads in bridged mode are not supported by Eversolo's specification. Two AMP-F8 units can be used as a monoblock pair for 500 watts per channel.

What gain settings are available and which should I choose?
A rear-panel switch selects between 23 dB and 29 dB gain. The 29 dB setting is appropriate for sources with lower output voltage or for speakers of lower sensitivity where more amplification is needed to reach comfortable listening levels. The 23 dB setting suits high-output sources such as many balanced preamplifiers. If you are unsure which setting suits your specific preamplifier and speakers, call or text All Elite Audio at 443-402-5055 or 443-402-5064.

Can I connect both XLR and RCA inputs simultaneously?
No, each channel uses one input at a time selected by its independent rear-panel input mode switch. However, the left and right channels can each be set to a different input type independently, which is useful in hybrid system configurations where the preamplifier has one balanced and one unbalanced output.

Does the AMP-F8 have trigger standby and signal-sensing auto standby?
Yes. A 5 to 12 volt trigger input and output allows the AMP-F8 to power on and off in sequence with a connected preamplifier or processor. Signal-sensing standby mode powers the amplifier down after twenty minutes of silence and wakes it automatically when signal returns.

What speakers pair well with the Eversolo AMP-F8?
The AMP-F8's 180 watts into 8Ω and damping factor above 400 provide authority with a wide range of speakers from approximately 85 dB sensitivity upward. It pairs naturally with the Eversolo SE100 passive bookshelf speakers, and with the DMP-A8 or DMP-A8 Master Edition Gen 2 as a source creates a complete high-performance two-box Eversolo system. For very demanding or low-sensitivity speakers, the AMP-F10 may be the more appropriate choice.

What warranty does the Eversolo AMP-F8 carry?
The AMP-F8 carries Eversolo's standard manufacturer warranty. All Elite Audio is a fully authorized Eversolo dealer, ensuring that warranty is valid and supported for every unit sold through our store.
