Ozzy -- if I assume the rest of your system is the same caliber as your amplifier (can I do that?) then I suggest you to "do it right" and have your speaker cables re-terminated. Even if you solder spades onto the bananas, you are creating a Rube Goldberg conglomeration of sound-degrading electrical interfaces -- and for what?
In fact, have spades installed on both ends if your speakers accept them too, because bananas (unless the locking kind, and not just a "push" connection) are an inferior connection IMO.
