Very efficient customer service

The V3 arrived with a faulty power supply and customer service immediately sent me a new one. The product is fantastic, worth every penny spent

Fosi Audio V3 amplifier.

This is a nice little amplifier with stunning performance and a love it. Using it to drive a pair of DIY full size stereo speakers (Valutronic SQ-50H).

A little hint. The outputs of the Fosi amplifier are independent (floating), so you can't take the signal to a mono subwoofer amplifier (where channel grounds are common), from to the left and right outputs of the Fosi (it will short the grounds and Fosi will shut off the output). Use the low level pass through from the Fosi, or your preamplifier (I'm using my preamp). In my case I then have to adjust output volume with my preamp.

Fun-Fi with Quality

Absolutely love this amp. If you don't need XLR then this one's for you. If you do need XLR, the ZA3 will be a better fit. If you need pure power amp with no volume, then the V3 monos are better fit.

What makes this amp great is how clean it sounds, and that with the stock op amps. If you are into op amp rolling, definitely give opa1612, opa1656, and opa2134 a try. They all sound really good. The best ones, in my opinion, will be the sparkos ss3602. It gives the best holographic sound while maintaining detail. I have used this amp to drive my Kefs Q150 speakers and it never disappoints. Can't wait to get the V3 monos to replace this one so I can move the V3 stereo to replace my Yamaha receiver in my kids playroom. You won't be disappointed in this purchase. Trust me. This product is a huge leap forward for affordable hi-fi gear that is great quality.

Good sound. Power output more like 50 watts per channel. I have it hooked up to a watt meter.
