I've done the same. The specs of even the cheapest switchmode power amp IC's are excellent, and most of the cheap boards just copy the IC manufacturer's reference circuit. Conveniently, the one I got can switch between a line input and Bluetooth, which improves the convenience factor even if Bluetooth might be of questionable audio quality. But with the line input, it's straight from DAC to the power amp. So far there are 3 of these setups in my house.
