– We do not recommend combining HAT sound cards on one Pi. But you can use any normal amps for the two outputs of the Piano.
– Not sure what you mean, could you clarify this question? If you have active speakers, a DAC would suffice. If you have two amp+ (need two Pi’s as well), passive speakers are directly connected.
