Sistrum Platforms under floor standing speakers


Has anybody tried using these platforms underneath any medium sized ( about 100 lbs ) floor standing speakers ? I understand what Sistrum is trying to accomplish, but I was just wondering about stablity while on the platform, sonic improvements..etc.....I am currently using ''their '' two inch Audiopoints to get my speakers off the floor and was wondering if spending the extra money would be worth my while on their platforms.

I have been using the bigger platforms under my Genesis 500's for several years now and have not had a tipping problem. It was hard as hell to lift those heavy monster speakers onto the Sistrums, but once we did, and got the platform spikes more or less evenly distributed under the base of the speaker, I have not moved anything and have had no problems. Sound with the platforms is incredible, as others above have noted. I was using 3 Audiopoints under each speaker before the platforms, and the platforms were a definite and immediately noticeable improvement. You can see the platforms underneath my Genesis 500's if you view my setup under the Virtual Systems link.
I went from the SP-1 to the SP-004 and finally the top dog SP-101. The improvement was incredible. I had the Audiopoints under my Thiels and the SP-101 brought my system to another level. What impressed me the most is they play louder. Try it. Keep your Audiopoints on one speaker and put the SP-101 on the other. You will check your pre amp to make sure the balance is not turned toward the Sp-101 and favoring that side. I have them under every piece of gear I own except my new cdp which I am going to call Robert and have one sent. You have nothing to lose. If I am not mistaken Robert said the SP-101 has never been returned.
Another reason I favored the SP-101 is my Thiels are very stable on the platforms. Which is important because I have a large dog who for some reason likes to listen to music. We have a understanding that he is allowed in the room with the condition that he is responsible for not letting anyone in there when I am not there. He might let someone take my watches or plasma TV , but when it comes to the SP-101 - well I pity the fool.
I'm experimenting with the SP-004 today under my Silverline Sonatina II's and I am very impressed (to my surprise). The sound is more articulate and almost SET-like (using Cary SLI-80), bass is tighter and cleaner and deeper. I have carpet and had been using the brass cones that the Silverline comes with, which look very high quality in their own right. So I did not expect this jump in performance from stands. They look good too. Like Dan, I'm using the two points in back and one in front. They are more stable than I had expected, albeit still a worry. The stock points screw in, whereas these points are resting under the speaker via a small brass-like cup.
