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

I like everything  in my system to be "just so"- e.g. cables organized, components perfectly aligned and centered in the rack, speakers positioned precisely, speaker cables run neatly, etc.

I have the personality that I need visual order.  Without judging anyone I believe that this is a form of expectation bias, a clean car with a fresh oil change seems to run better than a dirty one, a neat orderly system sounds better than a cobbled disorganized mess. 
 I have heard no benefit to speaker cables being raised from the floor but it does look neat and orderly and I can understand how that works.

it isn't that extreme, thanks for the suggestion.  

Monk anybody?

Isn't this a bit of a tip that some audio vendors can be quite predatory?
Also, I am suspicious of any tweak that is reported to take a few days or weeks to deliver it's benefits. That makes A-B comparisons extremely unreliable and magnifies the probability of user bias developing.
