My 300 watt sony shelf system broke, and I didn't want to take down the speakers I had mounted to the wall, so I figure a little amp like this will work to power the sound for my computer. I wasn't using the FM stereo, tape deck, or 5-disc CD changer, so this will save me power and space without wasting the speakers I already have. The 3.5mm line-in jack is a great bonus to the stereo RCA inputs.

As other buyers have noted, the power supply is the Achilles heel of this product. In my case, the power supply only lasted a few days before it died completely. Before the power supply died, the amp worked great. I used it to drive a pair of JBL bookshelf speakers in my office, and the sound quality was very good. I'm returning for replacement, and hoping the second try works out better.

A gadget everyone should own. For under $25 dollars, you can't go wrong with this little gem. 20 watts of clean audio reproduction in a tiny little package. I power two 8" speakers with this, hooked up to the DVD/CD player and my flat screen audio. I never turn it up past half-way in my 15' X 15' room- poor man's surround sound. I may buy another one for upstairs.

I got 2 that were DOA. The 3rd one has a mushy on/off button. I didn't want to return it, thinking Amazon might think I'm up to no good. I'm not even using it. Bought a Muse M50, not looking back. Eventually I will find a use for it but I won't be buying this particular model again. The quality control is lacking.

I have used many of these amps, and they are great. I have listened to music for hours and hours and I have not had a problem. I have not heard anything of this brand and I was a little uncertain about it, but this is the only one I will buy.

No problems, well, one problem. I listen to stuff with enough bass to make the amp s*** on itself a little. No biggie. If you really want you can replace the stock CAP with a 10,000 uf so that the bass shouldnt cut out as often

Bought this a long time ago and never reviewed it on here. The product is great, does what it's supposed to and has not failed me yet, I used it as part of my little homemade speaker box project.

Hooked up to iPod line out and a pair of JBL S38 studio monitors. WOW! This little amp is awesome. Volume at 50-60% is all I want and it fills the room with sound. I am delighted with this.
