I have my cables on Ikea glass candle holders that sell for about $.49/each. It's been that way for a long time now. After reading the dreck that usually pops up here, I remembered Pierre Sprey (Mapleshade) having something to say about them.
Looking it up, he's of the mind that cables should be at least 8" off the carpet to be free of it's effects. Already having a 6" 4x4, I went to the local hardware store and got four more cut to the same length for a whopping $10! Someone call the cable riser nannies!
It took about half an hour for the cables to settle in from the moving but there is more clarity now, even more than the 1 1/2" Ikea glass candle holder afforded.
This is a very cheap thing to try for yourself, so what's all the hubbub about?
All the best,
Nonoise
