Well, as a long-time subscriber to The Absolute Sound I've read/seen a lot of incredible nonsense. "Enid Lumley" whoever he/she was pursued this stuff. OTOH, some of the "tweaks" do make a difference i.e. unplugging and replugging all cables once in a while does make sense. How 'bout suspending your cables 2-3" off your synthetic fibre carpet to improve the sound with little tripods. That's a classic IMHO! BTW, I'm not immune to the silliness: I'm the proud owner of a Magic Brick to absorb stray electromagnetic forces. Oy! Caveat emptor!
