I demo'd it. Used it for several hours on a couple of different speakers (Some Wharfedale, Triad, and Snap's own).
It is a great problem solver. With it's size & features, there's not a whole lot else like it on the market.
Sound quality is what you would expect - it is a small box, that is cheap. Does anyone in this industry actually think anything more would come out of a box this size and at this price point.
It is thin sounding and runs out of juice early when cranking to a loud level - again, nothing unexpected. Would work fine on many different speakers out there, just would never pair it with speakers considered high-end.

Also, I was disappointed that the 3rd (center) channel can't actually be used as a 'center' channel from a surround system. The 3rd (center) output is a mix of the left & right channels, no other way to use it. That makes the 3 channel version of this useless IMO - expect for maybe the mono mode to drive 3 outputs the same for some reason.
