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

@millercarbon +1 0n lowerline insulators.  Lol i took a bucket in from the shop a numer of years ago ran them through the dishwasher  then tried  them a bid difference.  I made wood triangle stands before  they helpped the insulators  an even  bigger  benefit.  

Part of the problem in my situation is that power cords and speaker cables are all lying together in a small area. I don't have the floor space to separate them. 

LOL

Makes it easier when sweeping the floor in my listening room.
