I wanted a simple amplified stereo amplifier of the audio signal from a Bluetooth receiver and forwards on two old Life tower speaker. I had first flirted with a convenient built-in power amplifier finished, but was put off by the noise reports. This amplifier board is as far as I can judge 1A processed. It delivers excellent sound with a remarkable "Dynamic Range": deep rich bass and crystal clear highs. Both classical piano music, as well as loud Hand's-up beats are reproduced perfectly for my ears.
