Stillpoints Ultra SS vs spikes on concrete


My speakers are currently spiked on a solid concrete floor through medium weight Berber carpeting. Does anyone know if Stillpoints Ultra SS in place of the spikes provides a material improvement in isolation from vibration under these conditions?

Palasr - Thank you for your honest input and the (YMMV). I am going on the strength of Jim Smith saying that in voicing many systems every person liked the Herbie's products under their spikes. Mine are coming this week and I will post my mileage on this thread. I will be delighted if they work as they are cheap, and I will not be surprised if they don't because indeed, YMMV.
Gammajo, I just bought and put under my speaker stands 8 Herbies Decoupler/Sliders. I have not listened yet, will let them settle, a little wobbly but not bad. They will be under some Osiris speaker stands wityh Merlin TSMX speakers. Guy at Merlin said not to use them, but i am taking JS advice and trying them Will try this Friday night and post on this forum what i think or hear. Also could you do same? will be on look out on your opinion. Ps> they are on carpet.
Ryriken. You bet I will post and look forward to your input as well. My wife leaves tomorrow (Friday) for two days and my Herbies are supposed to arrive Friday - so I should be able to get in a good listen.
>>Pretty hard to get solid concrete to vibrate in the first place.<<

Nah, concrete resonates from one end to the other - its a great transport for external vibration.

I heard from a friend whose ears I trust; he spoke quite highly of the new Stillpoints with his Wilson speakers. You might email Paul Waukeen (sp?) at Stillpoints.
 
I was thinking of buying the SS Stillpoints.
But, I recently purchased the Herbie's Cone/Spike Decoupling Gliders. My speakers weigh 215 lbs each and have 2" Audiopoint spikes on them. The speakers spikes were sitting on a carpet (no pad) over concrete.
The Herbies under the spikes work great and now I am able to move these heavy speakers for better toe in etc.
