Cable Elevators - What do you use?

Based on a suggestion from the DakiOM site I experimented with suspending all of my cables - AC, interconnect and speaker - from the rack with cheap cotton string using small sections of foam water pipe insulation to keep cables from touching each other and the rack and I've been very pleased with the result. Big improvement over the ceramic isolators i used previously.
The result was a perceived reduction in background noise I hadn't noticed present before. Total cost about $3.00 USD

I use CD jewel cases.

otis makes the best cable elevators

The result was a perceived reduction in background
noise I hadn't noticed present before.

If you hadn't noticed the noise before,how did you perceive a reduction in it?I'm not doubting you,just trying to understand the statement.

Teajay: To be perfectly honest, if the improvement was there it was not enough to make me sit up and take notice. I feel better having them off the floor but maybe I need to go the next step and get the power cords off the floor. . . . More Yogurt cups!!

I want to know what others have experienced and what medium of elevators they used. Yogurt cups may not be the most scientific approach????
