Spaghetti cabling behind entertainment center

  I just do my best keeping the AC power cables away from the rest.  The DC cables don't seem to make a difference where they are, but I try to keep them separate.  I have a pic in my system page.

As far as keeping cables off the rug or floor, I've done that but notice no change.  I'm not saying there isn't one, just that it doesn't matter to my ears.  Try it yourself.  Use paper cups, or something like that to lift the cables and see if you hear a difference.  I use small wooden dowels with a wire tie to hold them together in a tripod fashion to lift cables over others.  Now that I think about it, I still have those ceramic insulators.
