Review: One of the best no-nonsense amps for music lovers/audiophiles with small to medium sized rooms… - I needed to gift a stereo system and I really didn’t need to think about which amp I’d pick up. It was almost a given. The Fosi, suffice to say, didn’t disappoint even when paired with speakers I originally didn’t mean to buy (I was looking for the Klipsch RP400M but couldn’t find them anywhere). And once I set the system up, the BT20A simply rose to the occasion, bad room dimensions and all. My only niggle, the volume increase is not linear. Turning up the knob doesn’t do much until about 25% up and then at 60% begins to amplify the sound exponentially. And it also does not have the resistive/expensive feel of the volume knob on the BT10A that I use as a personal desktop system Review: I am flattered by the sound quality and the tempting price. - Awesome product with superb sound quality. This can beat the amplifiers costs more than 10 times of its cost. I was not so confident to buy a class D amp as i always felt that class D amps lacks musicality. But this one made me a fan a Fosi audio. I am ordering P3 preamp now and wish to to try the ZA3 model too. Kudos to fosi audio for bringing quality products for affordable price. I am following fosi audio for new releases and their models will always have a place in my youtube channel techavmallu as reviews and ownership experience. ## Features - 300 Watts x2 Power Output: Provided by the TI TPA3255 chip which features an advanced feedback design and proprietary high-speed gate driver error correction.
