Accuphase makes two different power supplies, and one or the other is compatible with every amplifier that they make. For example a pair of A-300 monoblocks can be plugged into one PS-1250 power supply.
Accuphase would suggest that every one of their integrated or separate amps should be plugged into an Accuphase power supply. So the answer to your question is right there in their product line-up - starting with clean power for your amp.
