Review on KNACRO TPA3116PBTL 100W Single Channel Digital Power Amplifier Board - High Power Audio Module by Summer Zitzner

I bought this amp based on a recommendation from a DIY audio forum. On the first board I received, several components were not soldered. Instead of soldering for a repair I decided to go back for a replacement. The second board arrived in much better condition! Very clear sound when powered with 23V from a regulated power supply. Enough power to drive highly sensitive floorstanding speakers with devastating volume. The bottom of the board is marked Sanwu. There are also no pops when the amp is on. Overall I am happy with the purchase and would buy again.
