Easier than readin all that. Have her contact me and I'll have my wife write her back. She couldn't believe it (and neither could I) when I put the BD Racing cones under the cd player the very first time. I still don't "get it" and think it's voodoo BUT we did notice another large difference once I put the large DH cones under he pre-amp.

The references above are very good. I also agree wtih Imin2u that, in the end, all that matters is whether it sounds better to you. My experience has been that these cones create a very positive lift (no pun intended) with the cd player and a noticeable, but far less dramatic, improvement with the preamp. I've also noticed very significant gains with metal cones under my Thiel 6CS speakers -- these gains were even more dramatic than what I experienced with isolation cones used with the cd player. On the other hand, cones or spikes with my current speakers make very litte difference (they weigh a few hundred pounds each, so that could be why). Try it, you'll like it ;-) If you don't, be sure you're able to return the cones. There is no burn-in period. You'll know right away.

By the way, I'm very pleased with my Stillpoints Universal Resonance Dampers -- I use the base and the "cone".

What about Darumas under the CDP, rather than cones? And 5lb or so of lead shot (or other weight) on top of it?
