Can anyone explain cable risers?

There is a firm, scientific basis for raising cables off of the carpet changing the way that electrons flow through them. The carpet actually acts as part of the dielectric covering the conductors:

Taking the cables out of contact with the dielectric of the carpet will hence change the electron flow and fields within the cable.

Of course, the audibility of all this is up for discussion. Personally, my life is too short. But I would never dismiss the idea.

I use plastic-pipe couplers.

Tried some home-made ones. Couldn't tell the difference with or without. Try it yourself. You'll never know...

I think everybody has mentioned why they don't or do use them. I think the op needs us to explain(see the OP)what they do. So here is and explanation. Cables risers raise the cable off the floor. Got it so far? In doing so they dignify the lowly cable to audiophile status. It becomes not like a lowly beast of burden but something for the eye to behold and cause you to say 'you are my cables aren't you?'. Then it makes the cable feel important and in turn the it makes the owner feel proud. So to choose your 'raisers of the cable' whether it is toilet paper rolls or gold bars my recommendation is ask yourself how important do you want to feel. It is all in how you treat your cables I tell ya. So raise yourself up you noise lover and getcha some pretty cables rasiers.
