I am in the process of redecorating my theater. In the process I am redoing my speaker connection wall plate that currently has RCA connectors. My receiver has the 4 or 5 way (whatever it is) posts that accept banana plugs, bare wire, spades etc. My questions is: are there any preferred methods for the connections (wall and receiver in this case)? Forget the speaker ends for now as they are Bose (now please, I know, I'll fix it when I can afford it) with RCA connectors. Should I go banana plugs or what? Thanks!
