Review on Premium Desktop Audio Amplifier - HiFi Bluetooth 5.0, Class D, 300W+300W Stereo Power Amp by Christian Bar

I bought a Douk M1 Pro and was very impressed. Good sound. But I wanted a little more power so I ordered this simple little 300W x 2. The sound quality was terrible. Distorted, deaf, hoarse. And when it's delivering 300W x 2 (nearly double the M1 Pro), the audio volume is around 25% of the M1 Pro's 160W x 2. Those who wrote great reviews didn't have the same product as me, or they had different motivations, or they were just a small sample of the total number of reviews. While I can't stress enough how bad the sound was, it's well packaged and Bluetooth has a long range. I sent this amp back the same day I received it.
