weiliang audio Official Store - GOOD SELLER. Tested analog, USB and Bluetooth inputs. No problem.
The power supply of amplifier is only 40V DC. This is not enought to resive 150-170W at 8 Om at 1% THD. Necessary 55-57 V DC. Simple chande power supply impossible. There are capacitors to 50 V and XL2596S(max 45 V) at amplifier plate. Seller wrote: Maximum Power Per Channel: 101-130W. I think these numbers are for 4 Om. I liked the sound of this amplifier.
