AMP-F8
Class-AB Power Amplifier

With generous power in reserve, AMP-F8 delivers up to 500W at 8Ω in bridged mode, driving large floorstanding speakers with ease. From a focused listening room to a more open space, it gives music the strength to expand, the control to stay composed, and the scale to feel alive.
Stereo Mode:
180W per channel at 8Ω
280W per channel at 4Ω
Bridged Mode:
500W at 8Ω

With THD+N as low as 0.003%, AMP-F8 is engineered for faithful signal reproduction. Lower THD+N means less unwanted coloration, allowing instrument texture, vocal breath, detail retrieval, and layering to be reproduced with clarity and ease.
Total Harmonic Distortion + Noise (THD+N) as low as:
0.003%

With a 115dB Signal-to-Noise Ratio (SNR), AMP-F8 presents a cleaner sonic background. As the noise floor recedes, note decay, spatial layering, instrument imaging, and subtle vocal breaths emerge with greater clarity.

AMP-F8 offers professional-grade XLR balanced and RCA unbalanced inputs for easy connection with preamplifiers, DACs, and high-end source devices. Whether building a pure two-channel Hi-Fi system or upgrading an existing setup, AMP-F8 fits in naturally.
*With DMP-A8 Gen 2, a clean, powerful Hi-Fi system comes together.

*Working with DMP-A8 Master Gen 2 and the C10 Master Clock, AMP-F8 helps bring a high-end listening system together with ease.

AMP-F8 integrates a DC blocking circuit to suppress the impact of DC offset in the AC mains on the toroidal transformer, reducing mechanical vibration and potential noise interference. A cleaner power environment gives the amplifier circuit a more stable foundation, revealing a quieter background and richer detail.

For low-level audio signals, AMP-F8 uses a dual differential amplification architecture with symmetrical circuitry and precision negative feedback to suppress common-mode noise and external interference. With improved signal purity and linearity, sound stays natural, transparent, and stable through dynamic swings and subtle detail reproduction.

With a damping factor of over 400, AMP-F8 keeps speaker drivers precisely in check, even with large woofers and complex loads. Bass reaches deeper, stops faster, and stays clearly defined — with quick transient response and effortless composure.

Precision CNC-machined from high-grade aluminium, the chassis features clean lines, a solid structure, and a refined anodised, sandblasted finish. The thick aluminium enclosure helps suppress physical resonance, improve heat dissipation, and provide effective electromagnetic shielding.

AMP-F8 features classic analog VU meters that move in real time with the music. Each shift in level becomes clear, quiet, and beautifully visible. Seamlessly integrated into the clean front panel, they bring a warm analog touch to every listen. You hear the music. You see it move.

A custom 800W toroidal linear power supply delivers abundant, stable energy to the left and right channels. Independent power supply design helps reduce inter-channel interference, supporting stable imaging, stronger bass, and smooth, natural mids and highs.

AMP-F8 adopts a high-fidelity Class AB amplification architecture, with three pairs of precision-matched high-current MOSFETs for each channel. The parallel architecture helps distribute current more evenly, reduce distortion risks, and maintain excellent linearity across different loads. It delivers strong speaker drive with a natural, smooth sound texture.

A large filter capacitor array with 24 custom audio-grade filter capacitors helps reduce subtle power supply ripple and support cleaner current delivery. When dynamic peaks arrive, AMP-F8 responds quickly with ample current, keeping large-scale passages powerful and composed.

Premium speaker terminals are rigorously tested for a secure connection. With an optimised internal layout, AMP-F8 maintains stable thermal performance through extended listening and high-output playback. Solid materials and refined craftsmanship help it perform consistently, day after day.

Brings power and quiet into perfect balance
Whether building a purist Hi-Fi system from the ground up or upgrading your existing setup with a high-performance power amplifier, AMP-F8 integrates seamlessly into your acoustic world — bringing you closer to the original studio master recording and making high-fidelity listening part of everyday life.
