I have been around these amps alot lately. Of course that's due to the fact that I am currently living in Germany. The amps sound good, but are not over rated as far as power is concerned. Tests here have shown them to put out just under or right at their rated power. They are nice looking amps and pretty cheap over here. I can get the 5-channel for about $300 or so. They are sold at the large volume "Best Buy" like store here called Media Markt. Alot of people use them in SQ competitions here and do well with them. I think that their power output is due to them being so small, they are very tiny amps relatively speaking. Of course I have no problem with an amp that does rated power, I am just so accustomed to amps that do more than rated power...lol.
