Is There a Way to Lessen Vibration On Cables From Powered Speakers

UPDATE:

I found a successful solution!

Remember those foam pads?  They came from some electrical component shipping packing.  They're like EVA craft foam sheets.

Anyway, I discovered that if I sandwiched the cables between two sheets and used a rubber band to tightly apply pressure to the sheets, the cable that comes after that had significantly reduced vibration.  You could touch the cable before it and the cable after it and easily sense the loss of vibration.

I am going to experiment further :)

Okay well here's one to try then, sandwich the whole length like that.

@gaukus

When you sandwiched the cables, did the sound change for the better? Different? Worse?

@Millercarbon

I would need to get more foam sheets. At present I have sandwiched about a foot, just before the cables go off the desk.

@ghasley

The sound got better. It seemed as though there was more "depth" to the sound added.  Like the sound was thicker; if that makes any sense.

To be honest, I thought bunching them together would be detrimental to the sound. That the frequencies from each cable would somehow interact. After all, the higher tier Synergistic Research speaker cables, all the conductors are separated by a carbon fiber disk.
