Rated 5 out of 5 by from great little ampWe use these in a weatherproof outdoor sound system. They work very well all of the time.

Rated 5 out of 5 by from best purchaseI bought a bunch of these when they first came out on sale and built different things around them. First was a small box that I put 2 extra car speakers I had which were 4" coax, and that is used in the garage and sounds pretty good. Another was put in a small jewel box I got at a craft store and that could get hooked up to anything since it's easily portable.The 3rd and most often used was I got a nice cigar box and put 2 of these amps in and set it up so that one drives speakers in my living room while the other drives the ceiling speakers in my kitchen. The sound is great, I can't turn them up past 3/4 because it is too loud unless you're having a house party. When people hear it for the first time nobody believes me that they are only 15 watts because you wouldn't know.I don't remember exactly when I got them but it has been a couple of years and haven't had any problems so far. The 2 in the cigar box are used every day. So they seem well built.

Rated 5 out of 5 by from Very nice kitThis is a very nice, small amp, and the sound is terrific. The components seem to be of good quality, so far. The biggest issue I ran into was space constraints, and by cramming all the wires into a small compartment I accidentally unlodged the power connection ribbon - or I never lodged it correctly in the first place. Don't have to be gentle with this amp. I gutted a pair of the Philips 314113000201 R TMM 2-Ways and built a small set of desktop speakers. Would change the design if I had to do it again, but the amp is more than adequate. I think the sound is better than from the same speakers in their original housing being sourced by a Lepai, but there's some bias after pouring some sweat into these.

Hi there, Random question: we've used the volume potentiometer switch on other projects (since we either had a problem with the amp, or it didn't work). Can you tell me what the specs are for the volume potentiometer switch? Thank you!

Wired up per the manual. LED turns on when the potentiometer is switched but I get no sound, not even a little hiss at full volume. Source, Speakers and Power supply are OK. (TA2024 works in its place) Suggestions for troubleshooting before I return it?
