Thanks for the input. I have read quite a bit of it here, as well as elsewhere on the web. To some it is "snake oil" while to others it's very real. I haven't found a single local sales person (high end audio stores) that won't swear it's the most profound experience in audio. Fundamentally I'd like to try it myself. I don't really care about making it absolutely an unchallengeable test. I simply want to set up a test environment that I can make work for me… my ears, my speakers, my electronics, my room, etc. As to switching it myself… I can stab the switch a couple of dozen times and confuse my mind as to which selection is active. Or have my son or wife hit the button a few times when I’m out of the room. Then switch it myself after that. If I can hear a difference; Especially if I can hear a positive difference, THEN I can check and see which set of wires are active.
