I read somewhere about somebody actually comparing overpriced "interconnects" with a plain old metal coathangers, with no real difference. Is this generally true? I am starting to upgrade my playback rig, got a topping TP30 tripath amp on the way, I picked up a pair of "interaudio by bose" 2 way speakers (5 inch bass driver), just wondering if nice(r) cables would make any difference at all. Im guessing the answer is no until I get up into real expensive 'audiophile' stuff, and even then, it would only be minimal. correct?
