Most suitable and effective isolation platform


I'm looking for the most effective isolation platform for my TW Acustic Raven GT.
Current options that I'm familiar with (but haven't tried out myself):
1) SRA Ohio
2) HRS M3X
3) MinusK BM-6/8
4) Kinetic Systems "Vibraplane" ELpF

Would love to hear your opinions/experiences. Also, if you have other suggested solutions - feel free to chime in!

I have a custom SRA VR under my Galibier Gavia
it's 85 lbs

I specified the dimensions for extra room for the pod and record brush, zerostat etc

Kevin works on designs for lowering resonance of nuclear submarines

I have the table on an SRA craz rack
great isolation
worth at least looking at is the 'ultimate' solution; which is the Herzan TS-140 which is what use under my Wave Kinetics NVS tt here.

properly implemented active isolation will dramatically reduce feedback and is the only isolation approach that can stop and start, all passive isolation settles so is soft.

the Herzan needs a good quality grounded rack to be optimized. you would not want a decoupling rack and the Herzan as then the two isolation types would fight each other.
I have a Vibraplane from Sound of Silence. Works great for me. My SME 10 sits on Nordost sort Kone TC which sit on the Vibraplane. I think the SRA and HRS would work in conjunction with a Vibraplane or Minus K.

Based on what I read the SRA and HRS drain vibrations from your turntable. The Minus K and Vibraplane prevent vibration from getting to your turntable.

The Herzan is in a performance and price league of its own.
Thanks!
Mike, looking for the price of the Herzan I've come across a quote of ~$10000 - if that's the case - it's way off budget. Also, it would seem a bit overkill to place a ~$13000 TT on a $10k dedicated platform.
Jperry, you're saying that both are required?
An SRA/HRS platfrom under your table and the MinusK/Vibraplane below it? Or the other way around?
Sounds like a very expensive solution...
