Had used Aurios, tried Stillpoints.
The Aurios (esp Pro) are very good but can add a metallic sheen to the sound. They work better loaded with more mass(eg under the rack, heavy amp stands, etc) rather than lighter components (eg CDP). TCBs help but I prefer brass cones spiked into the central depression of the Aurios. This arrangement is more stable as well.
The Stillpoints are more subtle, seems to have less of an overt impact but more neutral presentation than the Aurios. I had experienced less setup hassle with them than the Aurios.
I would not imagine using either will result in the equipment "rolling off" the shelf in normal use. However, if you have little fingers or cats at home, it may not be the best idea.
I now use Aurios under my amp stands and equipment rack only. I have Neuance shelves under the amps and source components. I found the Neuance presentation most natural, for the lack of a better description. They were so good, I did not feel the urge to play the isolate/couple game any more.
Norm, I managed to further "improve" or at least differentiate with various footers on either side of the Neuance shelf. The type of footer can make a dramatic difference. And, some footers even take time to settle in ??
