Cable Elevators - What do you use?

I don't use them.

At the beginning of these posts I said that it doesn't make a difference....however....   I just tried the 1 1/2 in sections of toilet tissue under the speaker cables and actually do hear a difference.  The instruments are separated and not blurred (like wrong glasses prescription).   I'll go back and try it again, but as of now I'm a believer.   I noticed most high end cable has elaborate covering...mine is just 2 thin silver cables very lightly braided for each leg...that may be the difference.

@puerto

1. Could you please explain " what constitutes a scientifically smart elevator"?

2. Is you background in electric engineering?

Quick shout out to LIGO gravity wave detection experiment for winning the 2017 Nobel Prize in Physics. Couldn't have done it without tremendous team of vibration isolation experts.
