Stillpoints Ultra SS under your speakers?

I have been using Stillpoints for about a year in my system which comprises YG Carmels, Vitus 025, DCS Puccini and matching word clock,MD 108 and Entreq cables and silver Tellus.
When I put six SS Ultras under the speakers the difference was immediately clear. Reduced noise floor, greater transparency and a distinctly more musical presentation.I now have the SSs under the Vitus and the cheaper Minimus under other components. I have also heard them (Minimus) under less expensive Naim amplifiers and the improvement is significant.
I will upgrade the Minimus to Ultras in the near future.
I understand that YG are not yet sold on the benefits of Stillpoints but my ears tell me they do improve the already excellent sound of the Carmels.
In short see if you can have a demo set if at all possible and I would be surprised if you didn't keep them

Pardon me Richards for not responding earlier.The Ultra SSs are coupled to the speakers which are on a carpet,vinyl tiles and concrete floor.Minimal tilt on the speakers as they are firing across the room. Since then have added four under DCS Puccini and Vitus SIA 025 with Minimus under other components.
They really do make a difference and deal effectively with mechanical noise. There is still the problem of electronic noise and the Entreq Silver Tellus together with their i/cs and speaker cable really lifts the transparency, reduces the noise. and complements the Stillpoints.
The Carmel is a superb speaker and none of the upgrades set out above have phased them. They just effortlessly step up to new levels of performance
