Review on Powerful 2.1 Channel HiFi Bluetooth 5.0 Amplifier - Digital Stereo Audio Subwoofer Amp by Nobsound NS-14G by Stephen Lunn

Everything works fine. The sound quality isn't bad for what my limited hardware can handle, but when I plug the power adapter into the wall it produces quite large sparks. When I then plug it into my amp it also causes sparks. I'm in the process of replacing my power supply before it kills the amp. The product listing led me to think they were 200 watts per channel, but of course if I had read the fine print I would have noticed that it was 50 watts per channel. It's not a problem for me, but it's something to think about. In general I am satisfied with the amplifier, even if it works.
