The Fosi Audio V3 is a compact, powerful amplifier that remains very affordable. Despite its simplicity, the V3 uses high-quality audiophile components such as a TI TPA3255 amplification IC, Japanese and German Elna and Wima capacitors, and an NE5532 DIP8-mounted AOP, giving you the ability to swap them out if you want a certain sound character. This amplifier is ideal for integration into a HiFi system requiring high power as it outputs up to 2x225W @ 4Ω. Connections include a stereo RCA input, speaker terminals, and a 3.5mm pre-out jack.
The volume control is based on a logarithm (Taper A pot), providing much finer control that is better adapted to the human ear. This makes the final listening experience more immersive and enjoyable.
The Fosi Audio V3’s heat dissipation system allows it to be used at high power for long periods of time without compromising its performance or causing harmful effects. The V3 case features vents on the top and bottom sides, as well as an internal heatsink. This innovative cooling system design significantly improves the airflow and heat dissipation of the Fosi Audio V3 amplifier.
The Fosi Audio V3 uses the TI TPA3255 amplification chip to deliver true audio quality with Class D efficiency and very low distortion. Combined with audiophile components, TI’s TPA3255 allows the V3 to maintain high stability even at very high power. As for the OPA, the Fosi Audio V3 features NE5532s mounted in DIP8, making them easily replaceable. They can be replaced, for example, with MUSES02s, AOP2604APs or AOP2134PAs.
