I am getting ready to pick up my new Marantz SR-9200 receiver. I am going to rewire everything. One of my questions is, should I get speaker cable with banana plugs or just do what I have always done, just use the bare wire? The only bad thing about bare wire is I heard that after time it oxidizes and deteriorates your sound. I don't know how true that is but I would think it would take many years for that to happen. Also, I see alot of threads about BETTER CABLES, are they of good quality? I was going to buy some Monster Z series.
