Review on Nobsound 100W Bluetooth 5.0 Power Amplifier - Hi-Fi Stereo Class D Audio Amp, 2.0 Channel Wireless Receiver, Lossless Music Player, TF USB Home Speaker (Silver) by Russell Ross

I love the fact that class D amps draw very little power when not in use and can be left on at all times. This one is compact enough to hide almost anywhere; I leave it on all the time and use bluetooth to control it. The unit came with a 19V, 4.7A power supply that delivers maybe 40W peak power per channel; but it's enough to rock my bookshelf speakers. It also comes with multiple cables that allow you to connect it to almost any device you might want to use with it.
