B&W 802 and Stillpoints

Has anyone put their B&W 802's on Stillpoints? I removed the casters, and made plates to accommodate 1/4 inch bolts onto which I placed Stillpoints with inverse risers. This seemed to clean up the bass a bit, but there seems to be less overall punch...perhaps from having the speakers a bit higher off the floor? I'd be interested in anyone elses experience with these, or other alternatives.
hate to say it but I've actually tried my speakers on several different bases during a recent redux of my av world and I came to the conclusion that I could mount to a bed of Hostess brand snack cakes with no obvious impact to the music.

I think I have good ears but who knows!
I have tried my Parsifals on the hostess twinkee's and the cup cakes. I did not like either. The cup cakes made the sound to dark and the twinkee's added a bit of air and lightness at first but eventually I got tired of them and a little nauseous. I did try stillpoints once under a pair of Focal 1027be and did not notice any difference other than the still points would have been $1000 for two sets of four with risers. If I paid that I might have found a benefit. I do however feel the still points are easier to clean up after. I do use stillpoints on my electronics and find everything from modest to very significant benefit.
Thanks! Looking forward to more input. I've listened a bit more, and not sure I like what I hear. Maybe back to the casters.
Ralph it sort of sounds like you are working with hard floors given your description. What about using a thick layer of putty or elastomer. It seems that one method of this is to couple the vibration to an immovable object (like bookshelves on a stand with blutak) or to provide some isolation from vibration. In this case it seems logical to assume we are trying to decouple the speaker from the floor. One increases coupling and one decouples. How about a experiment where you go over the top in each direction to see which works. One is putty coupling to the floor, while the other is a urethane or something between the speaker and the floor to absorb (decouple) the speaker induced vibrations. Just a thought. Curious to hear what you decide/find. I was not kidding about not hearing anything in my system. That does not mean though that I'm not willing to experiment if someone finds something interesting.

I have recently put the Ultra Stillpoint footers attached with inserts under my Sophia III,s and the difference was a double-wow, but the real surprise happened when i did the same for a pair of JL-f113 subs and that,also, made just as drastic improvement. Not just in bass but mids and highs also. Even though i have the latest SP rack with all units on Ultras the difference under the speakers made the most difference. The rack and ultras were unfortunately put in last due to various reasons, but these made the difference of being totally satisfied and not quite happy.
