Eversolo Introduces the AMP-F8 Class AB Power Amplifier

The Eversolo AMP-F8 is a high-performance Class AB power amplifier designed for high-fidelity audio systems, featuring robust power output up to 500W into 8Ω in bridged mode. Key features include a massive 800W toroidal linear power supply, parallel MOSFET configuration, and a high damping factor (>400) to ensure precise control over speaker drivers and exceptionally low distortion (0.003% THD). The unit is housed in a CNC-machined aluminium chassis with analogue VU meters, designed for integration with high-end preamplifiers and DACs. You can explore this amplifier further, including its price and market availability, on the Eversolo website.

The amplifier’s power foundation centres around a custom 800W toroidal linear power supply with independent channels to minimise crosstalk and ensure stable imaging. Power delivery is further stabilised by an array of 24 custom audio-grade filter capacitors for rapid transient response, alongside an integrated DC-blocking circuit. This DC offset suppression mitigates transformer hum and mechanical vibration caused by AC mains interference, yielding a cleaner signal base and quieter backdrop.

With a focus on signal purity, the AMP-F8 boasts a Total Harmonic Distortion (THD) of just 0.003% and a 115dB Signal-to-Noise Ratio (SNR). Low-level signals are handled by a dual differential amplification architecture utilising symmetrical circuitry and precision negative feedback to reject common-mode noise. Additionally, a high damping factor of over 400 provides tight control over speaker drivers, preventing unwanted inertia and delivering tight, defined bass response.

In terms of connectivity and aesthetic design, the AMP-F8 offers flexible XLR balanced and RCA unbalanced inputs to integrate seamlessly with preamps, DACs (such as Eversolo’s own DMP-A8 Gen 2), and dedicated sources. The front panel incorporates classic dual analogue VU meters, offering real-time visual tracking of dynamic levels to balance modern digital setups with traditional analogue feedback.

Specification, Price and Availability

The physical construction features a CNC-machined unibody aluminium chassis finished with sandblasting and anodising. The heavy metal enclosure provides passive electromagnetic shielding, resonance suppression, and improved thermal efficiency. Paired with an internal convection cooling layout, the AMP-F8 is optimised for thermal stability and consistent, long-term performance during demanding playback sessions.
