Overview
The Fosi Audio V3 Stereo (48 V) is a compact Class D power amplifier that brings exceptional clarity, balance, and drive to bookshelf or desktop loudspeakers. Designed around the acclaimed TPA3255 chipset, the V3 amp delivers clean, powerful sound that captures both the precision of studio playback and the warmth of live performance. Every detail of its design reflects Fosi Audio’s belief that great sound should be simple, efficient, and deeply musical.
With the included 48 V / 5 A power supply, the Fosi V3 compact stereo amplifier delivers 300 watts per channel into 4 ohms, maintaining outstanding control and low distortion throughout the frequency range. Its dynamic, transparent presentation reveals subtle textures in vocals and instruments while keeping bass tight and articulate. This makes the Fosi V3 stereo amplifier ideal for near-field setups, compact hi-fi systems, and even demanding passive speakers.
Connectivity is simple and focused. There is one stereo RCA input and a fixed-level 3.5 mm pre-out for downstream devices. The stereo RCA input allows for seamless pairing with DACs, streamers, turntables with phono-pre built-in, or portable players. Left and Right speaker outputs support a wide range of speakers, while the minimalist front panel keeps operation intuitive and distraction-free.
Internally, the amplifier uses premium audio-grade components including Nichicon capacitors and precision resistors, optimised for ultra-low noise and wide bandwidth. With a THD + N of 0.003 percent and a dynamic range exceeding 110 dB, the V3 stereo amp produces a refined, fatigue-free sound that remains musical even at high volume.
Encased in a solid CNC-machined aluminium chassis, the Fosi V3 stereo amplifier feels every bit as solid as it sounds. The robust enclosure doubles as a heat sink for silent operation, while its compact form makes it perfect for desktop, office, or living-room systems. Every element — from the V3 Stereo gold-plated connectors to the precise volume control — has been engineered for long-term reliability and understated style.
For Groove Central listeners, the Fosi Audio V3 Stereo (48 V) embodies the perfect balance between power, purity, and practicality. It’s proof that great amplification doesn’t need to be oversized or overcomplicated — just well designed, beautifully built, and tuned for the love of music.
