Can anyone explain cable risers?

Is there ANY phenomenon, man-made or natural, that DOES NOT affect high end audio systems? Is there any phenomenon in nature or man-made that an audiophile CANNOT hear? This includes anything occurring in the Milky Way.
Cheers

Ok now. Man I love this country and this web site because now I know all about cable risers. Now lets discuss what might be the best kind of dog for a listening room because everything makes a difference. Or maybe for those of us aspiring to be a champion audio-philies what is the breakfast of champions. Or do some shampoos have a positive or negative effect on your-should I say it?-ears and thus your ability to go to tranquil musicland. Or maybe riding home from work in what kind of car puts you in the best frame of mind for listening to 'uriah heep'. Or maybe do any of you think greenpeace can save anything so we don't loose the natural sounds of things to all artificial sounds. I don't want to get everybody atwitter but the dna of many things has been modified making things unnatural. Anyway lets move on to something way more intersting now we know all about cable risers.

I once had a flood of water in my basement listening room. This was in the middle of winter and a freak warm front melted about a foot of snow in a few hours. My speaker cables at the time got soaked. So since that time I use cable elevators. Now I've just presented to the forum a 'Valid' reason to use them.! Additionally, I also think getting the cables off the vinyl floor tiles certainly can't be a bad thing in regards to eliminating dielectric absorbtion via the cable jacket touching the vinyl. Is it audible?- never really did the A/B comparison but it wouldn't surprise me one way or the other.

Apartment life dictates what kind of flooring one gets.

Oh, the agony.

All the best,
