Review: Wonderful amplifier in a compact design - Today, I've resurrected my 23 years old branded Hi-fi speakers to life with this compact & impressive amplifier. This amplifier can make any brand system to run for their name. Unbelievable loudness & bass quality. Make sure that your speakers are capable of handling the power of this amp. My speakers were 23+ years old. The power supply was 15+ years old PC adapter, 19.5v 6A. The result was a satisfaction that I've been longing for almost a decade. I think with more Voltage this can crank up even more. Thanks to InkOcean & desertcart.
