As a long time Stillpoint user and having heard the Parsifals using stillpoint stands and all components on a stillpoint rack including the amps I hardily agree that the Stillpoints are probably the best isolation device in dissipating energy as Davt notes. That particular set-up at an audio show was one of the most memorable audio systems I've experienced with much of it IMO the result of the extensive use of Stillpoint products along with a better than average room that allowed the system to open up without the typical room limitations at shows.
I am currently using stillpoints and risers, not the ultra, under all my components including the Merlin VSM speakers. The speakers are mounted on the speaker stands, 3 points. These are truly components that are beyond hype and really perform as advertised although why a stainless steel cone with ceramic balls would do what they do I am clueless. All I can say is they really work in opening up the soundstage, greater clarity of the harmonics, separation, that makes the music more there. Great product!
As a further note although not relative to your specific question. The Merlin's as you may or may not know are a highly evolved product that come with spikes provided by the manufacturer. These work quite well and in my listening comparisons with the Stillpoints note that the bass impact is better with the stock spikes. Having said that it was my also my impression that the Stillpoint speaker stand provided more of the music in all other parameters noted above.
