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.

I think I need to replace the potenomiter on  the DTS 2. Any suggestions for an easy replacement?

Asked by: BenBoccia

Can one volume/on off switch control 2 amps? 

Asked by: Zachy chan

I want to make a 2 way portable speaker. I'm planning to do mono, not stereo. Does that mean if I combine the power of both output leads into one, I'll get 30W? I'm planning on using the DA115-8 Woofer and ND16FA-6 Tweeter.

Asked by: Limo
No, this amp is not bridgeable and you cannot combine both outputs. You will have to use one channel of each amp.
