Disappointed

Great little amp. Used this to replace my klipsch ProMedia 2.1 amp, night and day difference. You have more control over the sound and the Bluetooth is a great feature. One thing I would like to see maybe in a future revision is a bluetooth antenna especially if you have the unit under a very thick wooded desk. Edit: I have noticed that when I shut down my laptop there is high pitch hum coming from the speakers, I’m using high quality audio cable. Very annoying.

Big Boom for the Buck!

It's a terrific little device except for the face it does need a 24v power cord. They give a piece of one. Do order one of don't have it. That's the reason it doesn't get 5 stars. You will have to build it to a degree but nothing technical. Otherwise, it BOOMS. I bought the 80watt and it rocks hard plus if you have a sub... prepare for techtonic aftershocks. Yes it can.
