Audionut sells these online... It is where I got mine:
To tell you the truth, no sonic improvements were heard by either me or my wife (who got me these for Christmas a few years ago...). I put them under the speaker cables which are are Nordost SPM, and these elevators have been reportedly able to improve their sound but... not.
Perhaps because my carpet is 100% plush wool (most carpets are or have acrylic)? Perhaps because these cables are kind of stiff and thin and wide that they do not really settle nicely in the channels in the top of the elevators (i.e. rounder speakers cables may work better)?
But, yeah, still use them as a 'precaution', just in case static starts building up after small micro-vibrations cause the cable to rub back and forth against the carpet.
Stehno is right. You can buy the same thing at any big hardware or electrical supply house. These are MUCH cheaper to say the least. Unfortunately, the ceramic used is not "audiophile grade" : )
These are called "cable hangers" or "wire hangers". They come in two different heights, one being much shorter at about 2" and the other about 5-6" or so. I would HIGHLY recommend using the larger ones or you will have to have a support every couple of inches. This is due to the natural sag that the wire has hanging from the suspension points. Sean
I bought some pipe insulation foam - it is sold at Home Depot for 80 cents to 1$ for 8 foot lengths I believe - it also comes in different thickness - it is used to wrap pipes to keep them from freezing. You can slice it however you want and either place the entire cable in it or cut the stuff to place as far apart as you like. It keeps the cable off the floor and from coming in contact with other power line cables that might add noise. It is dark gray in color and really does the trick. It also helps keep other cables from coming in contact with each other in my setup.
