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

There's one tweak I like but I am NOT making any recommendations here. It's called "Finyl"- you spray it (lightly) on your CD's and rub it gently to dry with a microfiber cloth (included). It's supposed to help the laser read the disc better, but it does polish the playing surface a bit. Supposedly you only need to use it once. I "think" it works, but it certainly does no harm- not like Armor-All- remember Stereophile's big discovery?! My cables are huge and heavy- just getting them to stay put on what they're connected to is tough enough. I even custom-ordered banana plugs for my Italian speakers, but the measurements are slightly off, so I wasn't able to insert them fully into the holes provided. I don't want to rain on anyone else's parade here, but High End Audio presents some exasperating challenges before you even get to sit down and listen. But my main objective is to get the best engineered recordings you can find First, no matter what your system looks like.

@nonoise I haven't had a chance to put down those IKEA holders--too much Christmas stuff going on--if you get there first let me know what you think.  There are many cheap solutions here but those had WAF.

@wyoboy, Understood: she who must be obeyed....

If all goes well, I'll be getting mine on Monday. I have no reason to think they'd work any better than what I'm using now, but they will look a heck of a lot better, and maybe, there'll be some more improvement once I move all my cables off the floor.

Merry Christmas, and a Happy New Year to you sir,
All the best,
Nonoise

if you have carpet try them.  hard wood floors spend money buying rounds at the bar  

and a Merry Christmas and Happy New Year to you as well--hope you're getting something audio for Christmas--i am--a nice 2 LP set of "Waiting for Columbus"--how do i know ?  I ordered it and wrapped it !
