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

Come to think about it, I already have a test setup for this baloney. I'm running an 8' pair of Audio Art that have improved the SQ from the previous Tara Labs. One channel is routed on the floor. The other through the floor it and then suspended though joists to the speaker.
The phantom center channel is rock solid between my ESLs.
It sounds like my Raal ribbon center channel is playing when it's not.
I hear and see no reason to suspend the second channel's cable
Nuff said.

I’ve tried it, but couldn’t hear a difference! I suspect much about cabling is overblown!

I  actually saw a system once where the owner had his $5K speaker cables taped to on-end toilet paper rolls (presumably by now he has special $1000 stands made of some extinct rare wood or mastodon ivory  or something).

I'm afraid that I laughed out loud (and when he blind A/Bed it I couldn't hear any of the 'immense difference' that he was claiming.

I’ve never been able to detect a difference, but I figure why not. I use Legos. Can be configured to any cable, height, even carpet color. $10

My vintage 1986 Monster Cables work flawlessly.  I don't run them along the floor.  They come out of the back of the cabinet at a very slight downward angle.  Then they get suspended from push pins with synthetic strings from the wall angling downward towards the speakers.  We all know current  flows better going downhill.....;-)
