I never said I believed the claims but its one of those things I had to try for myself. I figured there was no way static electricity could effect the sound since the wires have shielding around them. Funny you posted this because I'm watching a program on H2 about star trek technology...it hasn't said anything about elevating wires though.
Honestly getting rid of the crappy monster cable and replacing it with inexpensive wire from PE did more for the sound than elevating them. Much more mellow sounding without the brightness I had before. There are so many false claims out there its difficult for the consumer to to wade through the sea of BS to find the truth. There are some relatively convincing articles out there to "support" claims that various devices can improve the sound of your system and unless you have a strong science/electrical background you may be fooled. Personally I am a science buff and have taken an electronics course in high school and I'm still unsure about some of these devices/diy tricks.
