Although I
am partial to magic crystals (and purple), there is -- IMO -- validity to potential interference from static electricity (which I assume the cotton minimizes). I'll admit this here and then run and hide for a while, but I *did* use some cable lifters under the speaker cables in my previous house. No, not the portable negative ion eaters from Furutech, just some lifters made of ceramic that looked better than the empty tube boxes I first experimented with, had a little cradle to keep the cable in place, and IIRC were like $79 for a dozen of them. Getting the cables off the floor made a difference at that house which had wall-to-wall carpeting on a concrete pad subfloor. Not night and day, not huge, but noticeable. I didn't attempt to understand or explain it, I just heard it. My current house has suspended hardwood floors. Tried those same lifters here in the big rig, and I couldn't hear one bit of difference, even though I was expecting to. Nothing. So although my 2 data points are hardly worthy from any scientific standpoint, the static thing does make sense to me as it very likely existed at some level on the carpet, but obviously doesn't stand much of a chance on hardwood.
I'm still going to get 4 or 5 of those Furutech thingies to put under my headphone cable though. I figure if I lay my head on the table while listening, not only can I keep the cable level but I can watch the negative ions being eaten. May need to add a pillow for comfort. Just need to find out what the refueling interval and cost is first.
