Spades vs. Banana plugs ??

That's the rub - when they're screwed down tight. But what about next month? Still tight?

By adding bananas or spades you are doubling the contact issues: between either and the cable and between either and the speaker plug. Way better to go bare wire into the speaker using something like Mad Scientist’s contact enhancer. Spades get tightened and then loosen and bananas need good crimping.

+1 Bare wire.

Bananas or go bare by situation, bare gets tinned to forgo fraying....
