Review on 🔊 High-Fidelity Bluetooth Mini Audio Amplifier - Digital Desktop PC Stereo Receiver Class D (2 x 100 Watt MAX) Aluminum Diecast Construction - Pyle PDA20BT by Kathleen Roy

My Denon AVR 2809ci has lost its left rear surround, luckily it was the main amp section. The preamp's surround outputs were still working, so I decided to give it a try. Denon RCA outputs to PYLE amplifier input and PYLE speaker outputs to left and right surround. Initially the first amp didn't work properly, but Revain kindly provided me with a replacement at the same price. I paid ($34.99). Works perfectly! I've been playing around with bluetooth, although I'll never use it for that, and it worked great with my 2nd gen SE. Anyway, the RCA and speaker connections are solid, I used a banana connection. I kept the volume about halfway along with the tone controls. Very quiet, no sound/noise when nothing is playing. Let's get to work with movies now! I found class d in it is TPA3116D2, see photos. All caps are a good size. The only small problem is that the red line in the LED light is a bit bright. I used foil tape cut into a circle with a pin hole in the center to cover the LED. The power supply is a good size at 4.5 amps at 24vdc which is better than most. I always leave it plugged in and on because I've heard Class D suffers from popping when turned on or off. Overall I'd pay $50 knowing how well built it is and considering the performance. I will report any problems.
