Stillpoints and reference-level speakers

Agear,
Mechanical grounding is a fundamental issue and shouldn`t be ignored.Your comment about capacitors is interesting. I replaced the lone capacitor in my speaker crossover with a Duelund CAST and the improvement was immediate and obvious,it got better yet with time(it was money well spent). I`d say that placing the speakers on the Apprentice platforms resulted in an even larger margin of improvement(which is saying something!).This is good engineering/design with excellent implementation.
Charles,

Charles, how secure are your speakers on the new Sistrum stands? I assume not as stable as the old footers? Thinking about them for my speakers, but the current footers are very stable as my speakers weight darn close to 200 lbs each!

Grannyring,
You don't need to be worried; they are as stable as using cones or spikes, and once you hear what they do for your system, you will regret not doing it sooner.

Bill,
They are fairly stable but not as secure as the original cones due to 52 inch height and narrow footprint of the speaker(same cabinet as yours). They are in a seperate room and there`re no children or pets to worry about.The improvement is well worth it to me,I`ll just be careful around them.I use two platforms per speaker(speaker depth is 22 inches).
Charles,

I haven't tried Stillpoints under speakers but I found them undesirable under source components. I bought a trio of Ultra SS and tried them sequentially under my Brinkmann Oasis, VAC Phi Beta preamp, and Manley Steelhead II. In each case, I found them to create a lot of air and additional separation of instruments, which was good, but at the expense of mid-bass weight and overall tonal balance, which was not so good. Ultimately, I found my system more balanced and natural without them. Actually, that's true of any footers I've tried and I've tried a lot of them.

For context, I have Adona stands with their multi-element shelving, and I use a Minus-K platform under the Brinkmann. Without the Minus-K, I might have liked the Stillpoints more under the Oasis, but I can't say for sure. I know Jay Kaufmann at Audio Revelation loves them under his.
