EverSolo AMP-F8 Stereo Power Amplifier
Two Meters, 180 Watts a Side, and No Menus
The AMP-F8 does one job. It takes a signal from your preamp or streamer and turns it into 180 watts per channel into 8 ohms, or 280 watts into 4 ohms. Flip the rear bridge switch and it becomes a single mono channel rated at 500 watts into 8 ohms.
Two analog VU meters run across the front, calibrated in watts, with needles that track the music in real time. A switch on the back turns their backlight off. EverSolo left the front panel otherwise bare, which is the point of a power amplifier.
Measure Your Shelf Before You Order
At 10.4 inches wide, 15.3 deep and 4.7 tall, the AMP-F8 is narrow and deep rather than full width. It weighs 35 pounds. Each channel takes one balanced XLR or one unbalanced RCA input, and a rear switch sets gain to 23 dB or 29 dB.
What 800 Watts of Power Supply Buys You
A custom 800-watt toroidal linear transformer feeds the amplifier, with separate supply rails for the left and right channels. Behind it sits a bank of 24 audio-grade filter capacitors, there to smooth ripple and hold current in reserve for the loud parts.
A DC blocking circuit sits ahead of the transformer. DC riding on your household AC is what makes a toroid buzz mechanically, and older wiring and cheap dimmers are the usual causes. This circuit is aimed at that problem.
Three Matched MOSFET Pairs Per Side
The Class AB output stage uses three pairs of precision-matched high-current MOSFETs per channel, on separate left and right boards. Matching matters because devices that switch at slightly different points hand the waveform between them untidily, and that handoff is what a distortion analyzer reads.
Why the Background Goes Quiet
EverSolo publishes total harmonic distortion of 0.003% at 1 kHz and a signal-to-noise ratio of 115 dB or better, A-weighted. Crosstalk is rated at −95 dB or lower. Frequency response runs 10 Hz to 30 kHz, within half a decibel.
Damping factor is quoted above 400 into 8 ohms, a measure of how tightly the amplifier holds a woofer between notes. Both inputs present 10 kilohms. The chassis is CNC-machined from a single aluminum billet, cooled by convection through side heatsinks with no fan.
Who Is This Power Amplifier Best For?
- Your speakers are more than your current amplifier can handle — 180 watts into 8 ohms and 280 into 4 gives you headroom on low-sensitivity floorstanders, so orchestral swells and film soundtracks do not run out of room.
- You already own an EverSolo streamer or DAC — balanced XLR, unbalanced RCA and a 12-volt trigger mean the AMP-F8 wakes with your source and needs no adapters in the signal path.
- You want to upgrade in stages — buy one now for stereo, add a second later and bridge both into 500-watt monoblocks, so your first purchase stays in the system instead of going up for sale.
- You like watching the music as well as hearing it — the VU meters read in watts and the backlight switches off from the rear panel, so the amplifier can be the centerpiece or disappear into a dark room.
- You have a preamp, or a source with a volume control — this is pure amplification, with no volume knob, no DAC and no streaming built in. Feed it from one of our preamplifiers and the whole system comes together.
How Does It Connect to Your System?
Run a balanced XLR or unbalanced RCA cable from your preamp or variable-output streamer to the matching input on the back. Set the gain switch to 23 dB if your speakers are sensitive and your volume control bunches up at the bottom of its travel, or 29 dB if you need more.
Speaker cables land on gold-plated binding posts. Add the supplied trigger cable if your source has a 12-volt output, or let signal sensing bring the amplifier up on its own. Then plug in the power cord and leave it alone.
Pairs Well With
The pieces that finish a system built around the AMP-F8:
- Music streamers — a streaming DAC with a volume control drives this amplifier directly, no separate preamp required.
- Interconnect cables — no XLR or RCA cable ships in the box, so plan on a pair in the length your rack needs.
- Speaker cables — spades or bananas both land cleanly on the gold-plated posts.
- Floorstanding speakers — the big, power-hungry designs this amplifier was built to drive.
Frequently Asked Questions
What comes in the box with the EverSolo AMP-F8?
The amplifier ships with a power cable, a trigger cable and the user manual. Signal cables and speaker cables are sold separately, so order those with it if you are starting from scratch.
Should I use the XLR or the RCA input?
Either works, and both present 10 kilohms. Use XLR when your source has balanced outputs, especially on long cable runs. RCA is the right choice for the many preamps and streamers that offer single-ended outputs only.
Can I run two of them as monoblocks?
Yes. The rear bridge switch turns each amplifier into a single 500-watt channel into 8 ohms, one per speaker. Bridged operation is rated for 8-ohm loads, so check your speaker's impedance curve before you commit to a pair.
How does the AMP-F8 turn on and off?
Three ways. Use the 12-volt trigger input if your source has a trigger output, let signal sensing wake it when music arrives, or work the standby switch on the rear panel yourself.
Can I turn the VU meter lights off?
A switch on the rear panel kills the meter backlight. The needles still move, they just stop glowing, which is what most people want in a darkened listening room at night.
How much ventilation does it need?
Cooling is passive, through heatsinks along both sides and vents in the top panel. Leave clearance above and beside the chassis on your rack shelf, and keep the side fins away from cabinet walls.

- High-Power Stereo Amplification: The AMP-F8 delivers 180 watts per channel into 8 ohms and 280 watts per channel into 4 ohms, providing the power needed for many bookshelf and floorstanding speakers.
- 500-Watt Bridged Mono Mode: Switch the amplifier into bridged mode for 500 watts into an 8-ohm speaker. Two AMP-F8 amplifiers can form a powerful monoblock system. Bridged operation with 4-ohm speakers is not supported.
- Class AB Design: The high-fidelity Class AB architecture combines strong output capability with low distortion and more efficient operation than a similarly powerful pure Class A design.
- Matched MOSFET Output Stage: Each channel uses three pairs of precision-matched, high-current MOSFET power devices. The parallel design distributes current evenly and maintains stable performance under changing speaker loads.
- Independent Left and Right Channels: Separate amplification stages reduce interaction between channels, improving stereo separation, imaging, and placement of instruments.
- 800-Watt Toroidal Linear Power Supply: A custom high-power toroidal transformer supplies stable energy to both channels and provides the current reserve needed for demanding musical peaks.
- 24 Audio-Grade Filter Capacitors: A large capacitor bank helps reduce power-supply ripple while storing energy that can be released quickly during dynamic passages.
- Built-In DC Blocking: The DC-blocking circuit reduces the effects of DC offset in household power, helping prevent transformer vibration and related mechanical noise.
- Dual-Differential Signal Architecture: Symmetrical circuitry and precision negative feedback help reject common-mode noise and preserve musical detail across quiet and dynamic passages.
- High Damping Factor: A damping factor greater than 400 gives the amplifier firm control over speaker movement for tighter, more clearly defined bass.
- Balanced and Unbalanced Inputs: Balanced XLR and unbalanced RCA inputs allow the AMP-F8 to connect with a wide range of preamplifiers, DACs, and source components.
- Selectable Input Gain: Choose 23dB or 29dB gain to better match the output level of your preamplifier and the sensitivity of your speakers.
- Automatic Signal-Sensing Standby: In Signal mode, the amplifier enters standby after approximately 20 minutes without a usable audio signal and powers back on when a signal is detected.
- Trigger-Controlled Operation: A compatible preamplifier or source can control the AMP-F8’s power using a 5–12V trigger connection.
- Dual Analog VU Meters: Two illuminated front-panel meters display the output activity of the left and right channels. The meter backlight can be switched off when desired.
- CNC-Machined Aluminum Chassis: The solid unibody aluminum enclosure helps control resonance, improves electromagnetic shielding, and supports efficient heat dissipation.
- Natural Convection Cooling: The optimized internal layout and passive cooling design maintain stable operation without adding fan noise to the listening room.
- Multiple Protection Circuits: Built-in over-current, over-temperature, and short-circuit protection help protect the amplifier and connected speakers.
