This amplifier board is cheaper than the Bluetooth amplifier board I reviewed last time. You can buy it for less than $10. You can order it from China or Hong Kong.
It produces 20 watts per channel. It is very small.
The sound is amazingly good. With my Bluetooth amplifier board, the bass was lacking but this amplifier board plays bass.
I am using Sony Bookshelf speakers, SS-U310.
