Review on Mini Dual Channel Mixer Sound Stereo Receiver Box - 2X40W Home Audio Power Amplifier System with RCA, USB, AUX, Headphone, Mic Input, LED - Ideal for PA, Theater, Home Entertainment, and Studio Use - Pyle PTAU23 by Theresa Grieve

The amplifier is about 3 months old. So far, so good. I had one for 3 years before that and it worked fine. I switched to this one because it's bluetooth. Bluetooth connects very easily and quickly, without searching. This is a small amp so don't expect it to drive huge speakers. As a result, my Bose bookshelf speakers play better sound and are louder than I need. Anyone who really needs this compact amplifier will be satisfied.
