All materials have a sound.......I would not think that a ceramic riser would be best. You do not want to induce any microvibs into the cable. Also the ceramic risers do not raise the cable very much. I like to use cardboard. I have found cardboard to be very dead and clear sounding. You can make cardboard risers for essentially nothing and make them any height you want. For instance, you can cut a piece of cardboard 13 inches by 4 inches. You bend the cardboard at 5 inches from each end. You cut a slot in the middle of the end of each of these 5 x 4 inch parts and tape them together using electrical tape, scotch tape or glue.....even string, I would think PVC tape is less prone to static than scotch tape. The slot holds the cable. The deeper you cut the slot the more area it holds onto the cable. It looks something like a pyramid when done. Here is a link to some pics where you can see a very crude one I made years ago and still use today (no WAF here....he he):

If you have ceramic risers you might want to make some out of cardboard and compare. You can make them higher and you can make more of them so they support the wire even more. And they cost basically nothing. Fun stuff.
The Mapleshade three stick jobbies raise the cable 8 inches off the ground. Check these out:

You can make your own out of dowels, chopsticks or whatever. Be creative.....but get those cables off the floor.
