Woodworker- the Stillpoints are no bargain either. The Ultra SS can be bought in sets of 3 or 4, and the Ultra 5, i think it is called, is a more massive one that apparently provides even more effect. They also make a cheaper one, i think it is from aluminum, less of what Stillpoints can do from what I gather, but I didn't try those. If you search here, you'll see a ton of discussion about these products. The price can add up quickly, and many people who use them start putting them under many components in addition to their speakers. I guess the way you might approach it is to get a dealer to loan you a set or two, and try them under your CD player, line stage and/or amp(s).
I had Adona make me a very simple platform for the tube rectified power supply of my phono stage, and then proceeded to try all sorts of devices under the power supply. The results were interesting, and I posted them on another forum. Bottom line- I found the Vibrapod cones, plus pod (or disc) to show a demonstrable benefit and these are cheap as fast food. Other devices, like Aurios, were killer in terms of tightening up everything, but added a harshness that I couldn't tolerate. The HRS footers were good, but not as good as the Stillpoints SS. I also tried some proprietary rollerblocks, which gave some of the benefit of the Aurios, but not quite as strident. Of course, that's in my system, with my components.
