I have an OnkyoTX-SR800 and I have the choice of binding or plugging the speakers in. I asked an audio shop rep about it and he said he would bind because the plugs would corrode eventually. Hmm? I said they are gold plated. He said they will still corrode over time. I don't know guys. I never seen gold corrode. So can I get some input on the 2 choices. Corrosion aside, what are your thoughts between the 2?
