Rated 5 out of 5 by from No Distortion!!A high quality amp for such a low cost. No distortion at loud volumes!!

Rated 5 out of 5 by from Perfect choice for small (and desktop) speakersI'd heard good things about these small amps, so decided to pick one up to power the pair of Jeff Bagby's "Quarks" I'd built for my wife's office. What a pleasant surprise! ...this little amp drives the small speakers cleanly and with great clarity, and the tiny footprint made placement a breeze Absolutely, I'll pick up another for other similar projects and would definitely recommend to a friend.

Rated 5 out of 5 by from Very Nice Product.I have had this amp for 3 weeks and it was everything I had hoped it would be. Perfect size, well built, great sound and controls you would find on much more expensive amps. Easy to connect .

Rated 2 out of 5 by from Excessive EM radiationAfter reading many positive reviews about the amp I was looking forward to using it to replace a dedicated amplifier for a pair of speakers in my wife's sewing room. The sole source component is a tuner. Unfortunately the EM radiated by the amp (or PS not 100% sure) completely ruined the reception, so I had to put back the original amp, an 80's vintage solid state unit. The Lepai might be a nice little low power amp and perfect for some applications, but for me the EM interference made it unusable.

Rated 5 out of 5 by from Great Little Amp!!I bought this to power the little Dayton audio outdoor speakers for my deck. Works Excellent. With a little larger power supply it cranks up a bit louder. The one that comes with still works very good. and I am very happy with this product.

Rated 4 out of 5 by from Smooth Clean and Powerful but be CarefulVery good clarity and ample power. This is my third unit. The first does the patio ceiling speakers (yamaha 8") the second for a computer (Bose 141s)and this new one is being used to power Klipsh B20s in a small craft room. Shortly after purchase, I unwisely pushed the Lepai into clipping for a few moments. An hour later it died.Parts Express worked it out for us and is sending another. Good Product and customer service.

I'm trying to create a cheap outdoor movie theater. I'm thinking of pairing this amp with a pair of the Dayton 4" outdoor speakers (part # 310-030). Will this combo be able to deliver decent volume for outdoors. I will look to add a sub in the future.

Asked by: Mitch A
This combination should work relatively well as long as you don't crank the bass knob all the way up. Keeping the tone controls bypassed will allow for more output, you won't get much below 100 Hz from these anyway.

I have a 12v 5a & 12v 6a power supply. Can I use either one? Will be driving 2 Bose bookshelf & 2 6x9 Polk Audio speakers.

Asked by: Zoey
Yes either power supply will work with this amplifier.

Does this AMP have enough juice if I were to hook up a total of 4 speakers and each speaker was 100 Watts?

Asked by: dbmcm
As long as you do not go below the specified 4 to 8 Ohm rating it will work.
