Home made cable lifters.

I placed cardboard under all cables raising all cables in minimum of about 2 inches. That and seperating all cables including power had a dramatic difference on top end extension and seperation of instruments.

I wholeheartedly agree with clipsal. Just bend small pieces of cardboard into v-shapes. Notch them if you want to for greater cable holding stability, set them on the rug or floor, with v-shape pointing toward the floor, and place the speaker cables on the tops of the inverted vees or in their notches. The difference in sound quality can be heard easily. I tried the same with interconnects, but detected no differences in sound quality; however, system experiences may vary. In any event, costs nothing.

Are Audioquest DBS speaker cables immune to negative interactions with carpet contact?

Chadnliz, why would that be so? I have never heard any cables that are immune to any contact whatsoever with surfaces other than ceramic.

The best support for cables is across the bosom of 16 year old virgins. Don't skimp out here. Use as many as you can to keep them as close as possible to prevent sag. As mentioned above, avoid plastic fillers such as silicone. I doubt you could find a better way to keep the music more arousing.
