tony1954, Don’t try to understand or debate millercarbon. He is a tweaker supreme and is certain that his way of doing things is the only way. If you don’t buy less expensive gear and tweak the hell out of it, you are stupid in his world. All tweaks cause mind blowing improvements in sound. Trying to make sense of what he does will get you nowhere. If you want to know where he’s coming from read the Tekton Design Moab thread.
I wish I had a good answer for your original question, but I don’t. I try to avoid obvious problems like speaker cables running next to a power cable, but don’t get too deep into cable separation.
