My contribution may not be what you want to hear.
I've tried Stillpoints, Black Diamond Racing cones, some ceramic cones and various Sorbothane thingumies under my components, and I haven't found that any of them make a lick of difference. I've tried them under my transport, my preamp, my DAC and the amps - nothing, nada, zip. Part of the reason may be that I've got a reasonable rack on a concrete floor, but I have yet to hear any difference that's worth the cost (especially with Stillpoints - they're pricey little buggers!)
The one thing I tried that did make a difference was to put my tube DAC up on Feet of Silence. These gizmos essentially give the component an elastomeric suspension. I did hear a slightly smoother, cleaner sound that was (barely) worth the used price of the feet. I tried them under my tube pre and under the transport, and again heard no effect at all.
So, try them and see, but don't be surprised if you hear little to no difference. A lot of people report results, but I'm not one of them.
