Summary: Im not sure what the hype iis over a 200 dollar piece of plastic with a few capacitors and circuit boards is but this thing should of at least came with tone controls on it, the the treble is very brittle and the bass lack and kind of punch,
Summary: For the money, this is a remarkably good amplifier. I've been using a $500 tube amp in my office system but this amp beats it in terms of bass definition and soundstage. It's a simple, straightforward design and seems to be really well built.
Summary: I 've had this over a year and it has worked flawlessly. I use it in my office with my computer and iPhone and it has plenty of audio power for the job. I paired it with a Polk PSW-10 subwoofer with two ancient Radio Shack speakers and it sounds great.
Excellent driver of bookshelf or even floorstanding speakers but the front headphone port is mediocre at best

Summary: It's good but not perfect. I've been using it regularly for about a year now. The protective storage bag that's included makes it perfect for transporting. I have used this to drive 2 Polk floorstanding speakers and a PSW 505 12" sub, and it performed flawlessly.
