Summary: If you searched for this specifically, you know what it is. If you found this by accident, just buy it. The Sonic Impact (this is a very nice, higher-quality clone) T-Amp is legendary. These amps can make music that many amps in the <1000 range cannot touch. Silences are completely black, instruments clear, and voices are beautiful. Get some reasonably high-effeciency speakers and let them sing.
Summary: I've been using this little amplifier with a pair of 12W 8 ohm drivers (Tang Band W3-1364SA 3" Bamboo Cone, sold by Parts Express) for five years. They still sound beautiful, like the day I bought them. The amplifier receives sound from my computer, which has seen four different sound output sources since 2009. The speakers have reached impressive volumes with all of them. I've never had to turn the volume on this amplifier all the way up.
Summary: I bought this because my pervious SMSL Class T Amp was broken after 1year and 10 month of use, pretty short life span. When I hooded it up with all the same setting, I found that Dayton DTA-1 provided way better sound quality than SMSL!! The bass is more solid and firm, unlike SMSL projecting sloppy bass; the human voices are much sweeter too.
Summary: I got this so I could play music from my computer out on the deck. It drives a couple of Yamaha indoor-outdoor speakers and from a sound point of view it does a reasonable job, especially considering the price. I keep it in a Rubbermaid box on the deck and it has gotten quite sticky while it still plays OK.
Summary: and you know what's amazing about it? I found out something I havent even thought about before having a world class amp that is so small you can actually carry it with: Im now taking my bose small stereo speakers (two tops and a sub) when travelling for camping or to a hotel around the country.
