You really can't go wrong with this Class-D Amp.
It has lots of power to give , if loudness is a concern, without giving distorion. I find it perfect to power my passive speakers (Dali Spektor 2). It was the first one I got, and around this price point its one of the bests you can get.
Regarding its looks, some might say that the rackmount design is ugly, but I honestly like it a lot, and the meters are something that delights me.
