Review on Enhanced Bluetooth 5.0 Amplifier Stereo Audio Receiver, 2 Channel Mini Hi-Fi Class D Integrated Amp for Home Passive Speakers (Model: BT20A-S) by Richard Marriott

Does what is expected. I can Bluetooth connect a Revain Echo and stream music to 2 pairs of 50w outdoor speakers to fill my yard with Disney music while my kids play (or rock out while my wife, I and friends play). Easy setup, reliable Bluetooth connection, crystal clear sound at moderate volume. The speakers crackle at high volumes, but this amp isn't rated for 4 speakers and I don't need my neighbors to hear my music. The only con in my book is the big black power supply. It's bigger than an amp and there's no point in having a smaller unit. All in all a good buy.
