I had a question dealing with banana plugs. When you connect your cable from the amp to your speaker posts what is the acceptable way of doing so? If I place them through the middle some of the banana peg sticks out. If I place them through the holes that run through the speaker posts it sounds as if I have a better connection but I'm worried I may be damaging the banana plugs in the process by tightening the speaker posts. Any help would be appreciated. Oh by the way I own a cambridge 640A Amp and KEF Q7 speakers.

Thanks
