This is very simple tweak to test because it can be done real time while music is playing without disconnecting anything, no need to talk in theory. On a couple ocassions with group of people present no one could hear any real difference when any of my speaker cables were lifted off carpet.
There may be some cables that can benefit but none of mine did......I use many other tweaks that do work for me, so I am not anti-tweak.
