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

@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,

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 !

Has anyone calculated what difference such things done to make cables unreasonably expensive makes? Let us take an example. Many cable manufacturers warn us of high frequency rolloff caused by skin effect. They make cables like ribbons or bundle them in litz configuration where each strand of wire in individually insulated so every conductor is too thin to be affected by skin effect. But here is some physical calculation of how much rolloff can be expected with 8 gauge speaker wires in series with a 4 Ohm speaker. (I use magnetic planar speakers which do not vary in their reactance the way dynamic drivers do.) Skin effect will cause 4 meters of 8 gauge wire to have a resistance of 0.0164 Ohms at 20 kHz compared to a DC resistance of 0.00842 Ohms where more current can go through the center of the wire. Put this in series with 4  Ohms and calculate the difference between 4.0164 and 4.00842. Take the ratio and the log of this ratio times 20 and the skin effect attenuates the signal less than 1/200 dB.
That is why I am a little suspicious of over-priced cables and the questionable physics describing why you need them. The placebo effect is another matter which does not help.
That is why I think blind testing should be used more often. Can the dielectric effect of the floor on a cable induce a large enough fraction of a micro-volt to hear in the speakers? I do not claim some things could never make a difference one can hear but let the claims be reasonable.

Cable risers are just more snake oil.
