The V3 is a modern class-D stereo power amplifier by Fosi Audio. This budget audiophile amplifier competes on signal-to-noise ration with much pricier amps like the Marantz PM-90 (R18,000).
V3 Specifications
- SINAD: 88dB
- SnR: 110dB (signal-to-noise ratio)
- THD: 0.003% (Total Harmonic Distortion)
- Dynamic Range: 16 bits at full power
The 48V power supply squeezes substantially more performance out of the TPA3255 chipset than the standard 32V PSU. The previous generation TB10D left me wanting more with the standard 32V power, so I only stock the 48V version. These units come with a 24-month warranty.
Max Power
- 159W per channel into 4 ohm @ <1% THD
- 89W per channel into 8 ohm @ <1% THD
Peak Power
- 300W peak power per channel (momentary) totalling 600W
- 190W peak power per channel (CEA-2006/490A standard) into 4 ohm @ <1% THD+N
- 380W total peak power at <1% distortion.
Inputs
- Stereo RCA
Outputs
- Stereo speaker binding posts or banana plugs
- Lab Out (minijack / aux) for an active subwoofer. Note that a Lab out is not controlled by the volume knob (Pre-out is a misnomer).
Background
Over the last 10 years, class-D got good (the D does not mean digital). Class-D offers much higher efficiency (especially at idle) than older class-A or AB amplifiers.
Class-D amplifiers use pulse-width modulation to generate a pulse train output which is then filtered to remove high-frequency pulses. By turning on transistors only as-needed (usually MOSFETs), class-D amplifiers can achieve efficiencies in excess of 90%+. As a result, these amps are smaller, lighter and cheaper to build than their class A & class-AB predecessors.
I use the Fosi Audio V3 drive my KEF LS50 Meta speakers. They knock the socks off my old Crown K2. I also tried the budget Arylic A50+ integrated streamer + and would not recommend it (cold sound, distortion and cuts out at full power.)
You are welcome to bring your speakers for a sound test in Stellenbosch, or if you're nearby, I can come to you.
For more detailed measurements, please see Amir's measurements on AudioScienceReview.
