Review on Fosi BT30D-S Bluetooth 5.0 Receiver Amplifier 2.1 Channel Hi-Fi Stereo Audio Class D Integrated Amp - 50W x2+100W, Perfect for Home Outdoor Passive Speakers/Powered Subwoofer by Roger Gibbs

I have been using this Fosi amplifier for several days and I will share my first opinion. Build quality is excellent, although the rear connections are tight, but this is still a small amp. For some reason I have to re-pair Bluetooth every time the amp turns on and one day Windows wouldn't let me turn it off. I don't know if it's a problem with the amp or windows. After connecting, the Bluetooth works stably. The sound quality is good without a subwoofer but amazing with it. If you don't connect a subwoofer, you're missing out. I didn't have any of the popping issues that some attribute to the power supply. My amp is completely silent when no input is present, even at full volume, and is clear and crisp in normal use. I bought the silver version and the white letters are hard to see. My only disappointment is that this model doesn't have an auxiliary input, but I knew there would be. Overall I'm very happy with this little Fosi amp.
