The Eversolo AMP-F10 is a high-power Class AB stereo power amplifier designed to deliver substantial current, low distortion, and precise control over demanding loudspeakers. With 200W per channel into 8Ω, 320W per channel into 4Ω, and 450W per channel into 2Ω, the AMP-F10 is designed to maintain its performance as speaker impedance becomes more demanding. In bridged mode, it delivers up to 650W into 8Ω and 950W into 4Ω.
 
The AMP-F10 combines a 1000W dual-channel independent linear power supply, five pairs of high-current MOSFETs per channel, a symmetrical dual-differential amplifier architecture, advanced DC filtering, and a damping factor greater than 600.
 
High-Power Class AB Amplification
The AMP-F10 uses a Class AB amplifier design with Class A bias. Each channel employs five pairs of precision-matched, high-current MOSFET amplification transistors in a parallel configuration. Distributing the output current across multiple devices helps maintain consistency while reducing distortion and improving stability when driving demanding loads.
 
The amplifier's dual-differential architecture uses a symmetrical circuit design combined with negative feedback technology. This configuration is designed to minimize distortion, suppress common-mode noise, and maintain linear output across a wide range of operating levels.
 
Total harmonic distortion plus noise is specified at just 0.008% at 1kHz, while the signal-to-noise ratio is rated at 113dB.
 
1000W Dual-Channel Independent Linear Power Supply
The AMP-F10 incorporates a 1000W dual-channel independent linear power supply. Each channel has its own dedicated power supply section, reducing interaction between the left and right channels while providing each channel with substantial current reserves.
 
The large power supply is designed to handle demanding musical transients without compromising amplifier control or stereo separation.
 
Advanced DC Filtering Circuit
An integrated DC filtering circuit is positioned between the AC mains supply and the audio circuitry. It removes low-frequency DC interference from the incoming AC power before it reaches the amplifier's power supply.
 
By reducing DC contamination from the AC mains, the circuit helps minimize transformer vibration and hum while providing cleaner power to the amplifier circuitry.
 
High Current Output Capability
The AMP-F10 provides 200W RMS per channel into 8Ω, 320W RMS per channel into 4Ω, and 450W RMS per channel into 2Ω.
 
For systems requiring additional power, the amplifier can be operated in bridged mode, producing 650W RMS into 8Ω or 950W RMS into 4Ω.
 
This high-current capability makes the AMP-F10 suitable for a wide range of loudspeakers, including larger floorstanding designs and speakers with demanding impedance characteristics.
 
Damping Factor Greater Than 600
The AMP-F10 has a damping factor greater than 600 at 8Ω and 1kHz. A high damping factor allows the amplifier to exert greater electrical control over the loudspeaker's drivers.
 
This is particularly relevant in the low-frequency region, where amplifier control can contribute to tighter bass, improved transient response, and greater definition.
 
Balanced and Unbalanced Inputs
The AMP-F10 provides both balanced XLR and single-ended RCA inputs, allowing it to integrate with a wide variety of preamplifiers, DACs, streamers, and other source components.
 
The balanced XLR input is suited to systems using balanced preamplifier outputs, while the RCA input provides compatibility with conventional single-ended equipment.
 
Both inputs have a 10kΩ input impedance.
 
Adjustable Input Gain
The AMP-F10 provides selectable input gain settings to accommodate different system configurations and source output levels.
The XLR and RCA inputs can each be configured for either 23dB or 29dB of gain. This allows the amplifier to be matched more precisely with different preamplifiers and source components.
 
Wide-Bandwidth Design
The AMP-F10 has a frequency response of 10Hz–30kHz ±0.5dB at 1W into 8Ω.
Crosstalk is specified at ≤ -95dB at 200W into 8Ω and 1kHz, helping maintain separation between the left and right channels.
 
Construction and Reliability
The AMP-F10 is built around a substantial aluminum chassis designed to provide mechanical rigidity and protect the internal amplifier circuitry. The amplifier uses natural-convection cooling rather than a cooling fan, allowing it to operate without fan noise.
 
The combination of high-quality components, substantial power supply capacity, and thermal management is designed for stable operation during demanding listening sessions.
