Natalie, I think you are very wrong. The dielectric is very important. That's one of the very reasons to get the cables off of the carpet to begin with. And I wish you would do some research before you make absolute pronouncements like "the dialectric makes no difference". There are many, many resources to confirm that dielectrics dramatically affect the signal. Please do some reading and "listening" before you tell everyone else the moon is made of cheese.
And the "ceramic insulators" typically only get the cables off of the carpet 2-3 inches. Static is another big problem with the carpet and I am not sure that 2-3 inches is enough to be effective. Rub a balloon in your hair, hold it a couple of inches away and you can certainly feel the static.
I am sure audioengr or someone else with a better mind can jump in here to expound.
