Mapeshade cable lifts or any cable lifts?

When the cables are on the floor they are prone to the floor vibration in addition to other sources of vibration. Whether those cable risers will decrease it, unchange it or make it worse should depend a lot on those particular risers and their interaction with particular cables. Theoretically, the good ones should be able to improve the sound especially at high volume.

"Cables vibrating? I don't think so" I bet you don't think that speakers vibrate either.
"Quantum this or that". That happens too of course, but that's not what I was talking about. Elizabeth, you want something good for nothing; special treatment, in a manner of speaking. I can understand it; good luck to you.
Interesting thread anyway.

Great idea. After you are done with that put your sub on your head and determine the quantum sugnature of your vibrating..toe.
