The "reasoning" involved is irrelevant. Literally does not matter. If the cables are off the floor like you say then it matters even less. No cable that short is gonna be damaged just by running like that. Now if you trip over it, different story. But get real. Almost can’t even believe you seriously would ask. Only thing that matters is does it sound better. Only way to find out is do like I did and support the cables on a riser. Check it out.

Don’t waste your time here looking for reasons. All you’ll get is deaf bats never tried a thing but love to tell everyone who will listen all the made up "theories" and "reasons" they "believe" without ever having bothered to do the work to find out. Sad. Pathetic even. But there it is.
