Does raising speaker cables off the floor really make a big difference?

Forgot to add I am running tubes. A friend running solid state found that having them from the ceiling with red and blue yarn worked equally as well. You must alternate the colors. And suspend the speaker wire at exactly .93 the total wall height for maximum clarity and transparency. After approximately 273.5 hours of break in you will achieve maximum soundstage and details. Also the edginess will smooth out.  

Not funny.

I mentioned the yarn to my wife she wondered which would work best, cotton, wool, acrylic, silk, bamboo, hemp, linen or a blended?

Hemp or blended

audiozenology"Weave is a somewhat generic term meaning interlacing. A Berber carpet weaves a loop into a backing "

No it does not for that to be true such a carpet would have to be made on a weaving machine but it is not it is tufted they are two very different things that is a simple fact that you can either accept or continue to argue against kind of like a fish out of water that hopelessly flops about.
