Cable elevators

OP,  You may also look into elevators from Red Dragon Audio, I am using these to keep my flat cables above carpet to great effect. And they are quite inexpensive.

I have a set from Music Direct..so far the sonic value has been zero, they sit on carpet. My friends seem to get a good laugh out of it and like to remind me what a waste of money it was. I'm glad be to a source of inspiration for them.

It is possible that floor material (carpet, wood, vinyl) changes/adds to dielectric used in cable (that can affect the sound).  Energy flows from amplifier to the speaker on the outside of the cable.  I don't hear any difference but others might.

I want some so I can remove some slack from my speaker binding posts from these heavy Audioquest wel cables.

@maxboy00 ,  thank you for sharing your experience with elevators. That's what good friends for, they do keep it real :-)

IMO, tweaks are very much components or system dependent and above all user ability to discern any improvements - good or bad. 

From my experience, carpets is the worst kind of flooring as they causes static interference which leads to signal degradation. Plus elevators keep your cables in pristine shape and in some cases enhances the overall look of your rig.
