Do banana plugs do anything other than make it easier to connect speaker wire? Or is it an excuse for Monster to make something and overcharge us for? I have read that speaker wire (being copper) has the ability to tarnish quicker (which I have seen after moving, unhooking and then rehooking my speakers to my receiver). Does a faded or tarnished connection really alter the sound that much? Most banana plugs I have seen are gold or at least gold plated which don't tarnish and should, theoretically, make a stronger connection. Is one brand of plug better than the other (i.e. Radio Shack versus Monster)? I am asking this after I just bought a 5 pack of monster banana plugs - I guess I am a sucker for those guys.
