Does raising speaker cables off the floor really make a big difference?

We must think alike, I did the same thing, next step is to use Foster's 25oz cans, I know I know a bit more expensive but it really ups the game!

I performed an experiment a few years back when my system needed to be taken completely
apart and moved to a different room in the house.  I had  an approximate total 300' of speaker
cable running the tri-amped system. I know sounds ridiculous (actually great).  The new location required much less cabling, but being a lazy SOB and doing this in stages I hadn't
cut and soldered ends on the cable, so they remained way too long.  I simply coiled them on the floor, yes bass mids and highs 10 gauge cable makes quite a stack of copper. An audiophile buddy correctly pointed out that  those cables had to be inducing some kinda voltages in each other due to proximity.  I agreed, but I can't hear it. Remember new room new SQ but no apparent problems.  Fat story slim..........I only turned on the bass amps (two ARC mono-blocks) and let some music rip, greater than a kilowatt going to the two woofers.  And guess watt (pun intended) neither the mid or highs made a peep!  I was very amazed.  Not a perfect experiment by any means, but that is watt happened.  Hence I'm not into cable elevators. One last thing (before someone asks) all of the drivers will play the other drivers
freqs.  Tried that as well although at a very low volume. The tweeter will make some "bass"
noises and the woofer will make some tweeter noises. The mid-range is almost full range.

I never argue about tweaks, waste of time.
