Footers under big heavy speakers (Stillpoints Ultra 5, Sistrum rack, Finite Elements,..?)


Revisiting isolation and coupling for my main system, I wonder if I would try better coupling devices than the large Symposium Svelte shelves (19"x24") I currently have under my Duntech Sovereign 2001s with 21" w x 35" d wooden base, weighing 360lbs each, which in turn rests directly onto wooden floor. My room was pretty lively before the isolation/coupling and I need better coupling/draining of energy for the speakers. 

What would you suggest?

I could try four Stillpoints Ultra 5 with base under each speaker or what I hope to be at least equally good and more economically is a pair of Sistrum rack platform (using AudioPoints 1.5) that measures 22.75"x 26.75" (I don't think their standard speaker stands can provide enough balance). I could buy a Sistrum SP-4 rack and use two platforms for my speakers. This would be budget wise the same if I would buy two Apprentice SP-SA-XL-4-1.5 (18"x24") as I am looking for a new rack for my second system (Home Theater). 

Star Sound seems to be a very reputable company but earns less coverage than, e.g. Stillpoints. 

The third and probably least talked about solution would be Finite Elements Cerabase but I find less buzz here on the Gon.

I use the Sistrum Apprentice XLs under my Revel Salon 2s and am very happy with their performance.
Black Diamond Racing Super Jumbo Pucks can take the weight of big speakers 200 lbs and more. I've used them previously with very good results...
I cannot comment on the other potential solutions you are exploring, but can share that I am extremely pleased with Stillpoints Ultra 5s under my Tidal Contriva G2 speakers (225 lbs. each). Compared to Stillpoints Ultra SSs (which were quite good), I immediately noticed more precise imaging and better defined bass. 

After using Stillpoints and a few others including 2" Audio Points under my 215 lb Eggleston Works Andra ll's, I then tried the large SS pointed footer version from Amcan. I was impressed and I am still using them.

There's a guy selling stillpoints component stands on agon for a pretty good deal right now.  

I have those under my exemplar horns to good effect.

Can add ultra 5s to the component stands down the line and basically get the equivalent of ultra 6s for my speakers. :)
