Updated. I received a few emails regarding the use of cable elevators with our cables. Do they make a sonic improvement? A little discussion follows.
Carpets can hold static charges so theoretically if the cables are moved within the carpet strands there could be static induction into the sheath.
Some folks claim that the carpet is a dielectric referenced to earth ground via a concrete slab that can affect the audio signal.
Tip: To control static charges in carpets, mix (8) tablespoons unscented Downy fabric softener to 1 quart water in a spray bottle. This method is used in industry to protect electronics from static discharge damage.
