Stillpoints are not brass cones. They have some type of bearings inside that work to isolate the piece of gear. I had a set of them for a short time and found them to do absolutely nothing. At the same time I had several sets of Aurious bearings and was very happy with the improvement they offered to the soundstage.
My expereince will only translate to a similar arrangement, I think.
My system is set up in the basement, therefore the floor is quite solid. I still expereinced improvement in the tightness of the bass and soundstage with the Aurious and later with brass cones. I have replaced all of the other bearing type componants with brass cones. The cones have been as effective as anything else, but at a fraction of the cost. I have had my cones made for by machinist acqaintenences. As a matter of fact I just picked up a 3" brass rod about 36" long to have some more cones made.
I don't know if this helped, but... that's all I know.
