You can use bananas no problem. Accuphase spkr terminals are actually designed to avoid accidental shorting but you can use bananas instead of spades or raw wires.
I don't need the A80, and yes, the P7500 is another dream amplifier, but I'll stick with Class A.
Oh in case you don't know, the horizontal strip that intersects the heat sinks on both sides of these amplifiers including the A48-S are actually handles. Yes handles! The Japanese think of everything.
