Isolation Platform for my Sota Cosmos?


Delving into the murky waters of all things Isolation Platforms to complement my Sota Cosmos turntable to try to understand which - if any - isolation platform would work best with my Sota Cosmos turntable - which is a suspended turntable. The Cosmos already has great isolation qualities so i am wondering if there is actually anything out there that could improve the sound quality from this TT. Any suggestions? Thank You

I posted a picture on my system page for those interested in how the foam looks sandwiched between my turntable and shelf. I'm still enjoying the improvement it made to the clarity of the bass and the more focused images.
I have a suspended turntable and recently bought a self-leveling Vibraplane to place underneath it. The improvement was clear. I then ordered a custom steel ballast plate which weights 136lbs. This is large enough to also place my motor controller on it. This increased the performance even more. I have a very solid, rigid DIY rack with lolli columns in the basement supporting the floor under the rack, so there is no bounce to my suspended wood frame floor.

Proper, serious isolation solutions are a very effective way to improve turntable performance, even if the turntable is a suspended design. Photos can be viewed on my system page.
I had better isolation under my tt years ago and drifted away from that. Somehow, years ago I thought a granite base would be advantageous. I then learned some time ago that the tt sitting directly on granite was not a good thing. Now I have learned over again that the more isolated my tt is from the granite the better. I have listened exclusively only to vinyl the past few weeks having a rediscovery how good analog sounds. The bass is once again crisp and deep; as good as or better than digital. Imaging is tack sharp. This past Sunday night I was listening to Dark Side of the Moon. I was delighted to experience the holigraphic sound stage of this album again after several years. The oval pattern of the sounds moving left to right and back at the beginning of the record was very apparent; as well as the oval pattern in the footsteps on the next track.
Tonywinsc, As my system has improved, those sounds swooshing around in an oval patter have moved from above the plane of the speakers to now where they are circling above my head. I have not gotten the oval to go completely behind me yet, but it is indeed an amazing effect. A bit like helicopters in a big Summer Blockbuster movie. This is an LP that continues to sound different as the system changes.
