What do $2500 speaker cables sound like?

I would think that real wood with have no impact worth noting, except for the vibrations that some say can have an effect. I've seen lots of photos of reviewers set ups where it's about 50/50 as to whether they're off a wooden floor or just lying on it. 

The reviewers who have them off their wooden floors claim to hear the difference. The others don't even mention it, kind of like here.

This is going out on a limb but the thought of a layer of non organic  clear coat on a wood floor (for that long lasting sheen and protection) could be a factor but you won't know until you try something. 

Like having a thin wire in a big tube, only a small part of the cable will be making contact with the floor so it probably doesn't matter. If I had wood floors, I'd still try it too see for myself, starting with something cheap and temporary.

@sokogear,
Not all of the cable is 30" off the floor. I tried to depict the image of longer than needed cable drooping as I hung it, with sections of it at the 8" height off the floor. Not all of it is 30" off the floor. 

As the crow flies, one speaker is about 4' from my integrated and the other is about 2 1/2', while my SCs are about 8' in length.

The thought of static electricity ran through my mind as well. It's only on the synthetic carpet in my apartment that I can build it up to the point where I'll shock myself, so it stands to reason it may have been interfering with the sound of the cable all this time, acting as an additional layer of unwanted dielectric. Who knows? 

All I care is that it sounds much more convincing.

All the best,

Agree with raising the cables off the floor. I started out with short tea candle holders from Ikea. Real cheap and easy to lay cables on their scalloped edges.

Next I tried some 6" 4x4s and was impressed with the improvement. I remember Pierre Sprey of Mapleshade saying to get them at least 8" off the floor so I went and got some of those 3M stick on hooks for one wall behind the speakers and strung up the extra length on them, about 30" off the floor. Not all of the cable is that high (one section is as close as 8" as it droops-the cables are about 2’ longer than I need).
For the other side, I had to go with a short wire TP holder (25") with an extended handle (for that roll) to use to lay the cable on due to its proximity to the wall heater.

As funny as it sounds, it’s not in the least funny in how it sounds. The clarity is so pronounced that solo voices with acoustic accompaniment sounds so eerily real as to beg disbelief. That goes for all around clarity as well on any recording. The only trade off is getting used to a somewhat lessened lower mid and bass performance.

It seems that the smearing introduced by my synthetic carpet added some heft to the sound in the lower parts. To think that I’ve read of this many years ago (closer to decades) and didn’t take it all that seriously gives me pause. I always thought that my Marantz had that relaxed house sound but with everything I do to clean things up (power conditioning, footers, fuses, and now cable management) the more the sound is not relaxed at all, but just ever so slightly warm off center, but capable of lots of detail and depth.

All the best,
