Fosi Audio V3 Stereo Power Amplifier Home Audio 300 Watts x2 TPA3255 Class D Mini Speaker Amp 2 Channel Audio Component Amplifier for Passive Bookshelf Tower Speakers for Desktop Home Theater

This amplifier is a must-have if you're connecting multiple speakers, as I have, or simply setting up a stereo system. I’ve been using it as a power amplifier for my Atmos speakers in my dedicated home theater. My AVR has pre-outs, so I connected the Fossi amp to the AVR and then to the speakers. It’s doing an excellent job. I’ve been using it for over 7 or 8 months, and I haven't experienced any issues. As a driver for Atmos speakers, it easily handles both heavy bass and high frequencies. I have not tested it for stereo listening. Overall, it is great value for the money.

Works superbly with Fosi audio P3 tube pre amp. I wanted to reuse Sony hi-fi systems speakers and it serves the purpose. Now audiio output and quality is better than original Sony system

Well built.I bought it as a second amp for a new setup . Can deliver adequate power to my ELAC 50 W speakers without any issues. Lacks warmth or fullness. If you are used to hearing on good quality amps, you will certainly feel the difference. But for the price it packs enough punch for a basic setup. No noises.

This is fosi V3 plain stereo power amp.I didn't go for other BT model from Fosi, because I got blueme HD as a BT receiver..I m a musician and also sound recordist, always given preference to analog audio equipment including Vinyl and Magnetic tapes, until recently shifted apple music..I owned Rotel, Yamaha, Denon,Pioneer almost since 40 years with speaker choices to Jbl, Bose,KEF (VINTAGE), Elac ect....I don't know how will I react to fosi a Chinese company with Japan, Japan, Japan and German Components inside..I tried only this Power amplifier..At 32v DC I don't know if it can deliver truly 100 w pc RMS...I DON'T CARE...This is most beautiful sounding amp I HV ever thought for its price to satisfaction ratio..Trust me and go for it keeping your mind and eyes closed..No second thought...Thanks Fosi...Keep it..Today Nov. 2 2024I recently added Fosi Preamp P3 (as P2 not available)This has made it even better sounding system with KEF Cresta 1Paisa Vasool!!!Sunil

Fantastic small amplifier, Value for money. It requires turning the volume button to high to get reasonable sound, but it is not an issue. I am using it for amplifying the back surround speakers in Dolby Atmos system pairing this with large 9.2 amplifier. Worth the price. I would recommend it.

Bought this amp a week before. Buildwise it's solid and soundwise Very neutral Amplifier. I'm using it with Aiyima DAC A2 and surprised how good the songs are played. One thing I noticed is we need to keep the amp volume knob almost to the end of dial to get the good volume.Noticed today that BT20A Pro version released with additional features. Cost wise both are same and I think BT20A Pro is VFM amplifier among the two.

Very balanced sound without preamp , very crisp and clean sound

The Blue light is eye-piercingly bright. The kind that burns your retina.The space between the output connectors is laughably small, as are the connectors themselves.The RCA sockets are out of spec - all plugs are an extremely tight fit.There is no pre out in spite of the label. It's basically connected to the RCA sockets.There is some residual voltage on the ungrounded power supply if you use a mains tester on it, but it is below 15VAC and this is not a concern.Other than these niggles, it's sort of usable. I would have preferred a little more thought being put into the feature set, but I guess there's a limit to the thoroughness of the design .The sound is very good. I would rate it as a good Class D implementation, very rare in and of itself. For casual video use it is adequate, for stereo music it does the job with some lack of refinement. I connect this to a pair of Usher S-520 and it's fed from a few different sources, the best being a Benchmark DAC-2. I'm using a 48V Meanwell 200W power supply, opting to not limit the amp with the included brick. The Meanwell also has extremely low measured noise and it's grounded, so that's a bonus.For comparison, I was using the Aiyima A08 Pro in this setup (and earlier the A07) and while that had more gain (along with a bunch of other less useful bling), this is definitely a better sounding amplifier. At the ~8k price point, it is worth spending money on. The ZA3 offers very little meaningful uplift and the step down to the Aiyima A07 is not worth the savings (if there are any).
