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

I tried some purple and pink hemp rope spun together. Then today suspended from the ceiling with a 20 pound spring from a 28 ton Crosby shackle. I hung a 3’ 3/8” wire  rope sling also from the shackle. Dissimilar items so high and low frequencies can be adjusted with length of each. I wrapped the hemp around the wire rope sling at a rate of 3-1. 9 wraps for every 1 foot of length. Put the tail through the eyelet. Tied the rope to the wire suspending the wire at 1 3/64th above the hardwood... I also laid a 3” strip of carpet under the wire to prevent any resonances from the hardwood. And I have to tell you. It’s been the biggest change to my system. Made my speaker friggin sing.... Going to do the same to the interconnects next. Except I think they will need a 45 ton shackle. 

Yes it took me months to try this all out. And a few minutes to report back. 

Forgot to add I am running tubes. A friend running solid state found that having them from the ceiling with red and blue yarn worked equally as well. You must alternate the colors. And suspend the speaker wire at exactly .93 the total wall height for maximum clarity and transparency. After approximately 273.5 hours of break in you will achieve maximum soundstage and details. Also the edginess will smooth out.  

It didn’t make any difference with mine. Until I ran them across the ceiling. Attached to ceramic insulators used on the old high power lines. Everything opened up them. Clarity, transparency, and lowered the noise floor drastically. You must separate the power cords and interconnects though when doing the with them. Every little bit helps. Oh, I found Velcro from the ceiling works best with the power cords... who would have thunk... 

Hemp or blended
