Glrtgi,
I have a similiar situation to yours. My speaker wires have banana connections and which my amp accepts. Of course I have kept an old receiver as a "just in case' back-up amp, in the event that I might ever have put the amp in the shop. The only problem is the receiver only accepts spade connections. So guess I need to hit the Rat Shack to see if they might have an adapter that would convert from a banana connection to a spade.
Now as far as your question "Would it be advisable i.e. worth the $ to get a second set of speaker cables with banana terminations in order to maximize the sound quality?", my answer would be "NO". The distance involved in between the spade and banana is so miminal to have almost no real effect on the performance. Now if having to use adapters is bothering you it might be better instead of getting a 2nd pair of speaker wires, is to have the "taps" on the amp that accepts only banana plugs change out to ones that would accept both banana and spades. This should be a fairly easy and not to expensive change, certainly less expensive than buying a second set of quality speaker wires.
