Ridiculous price for an amp that is the way! For a small room sound use or for a festive occasion that is very effective, the sound is very good and in any case much better than a HC amp. Only downside: the line input jack 3.5 format is rather poor, promote RCA input (for a phone to take a RCA jack cable is much better) ... and use a lossless format preference. No power supplied, this allows to choose a regulated and quality. Too bad the terminals are cheap but the price is also cheap, so I can not possibly put this in negative.
