Never mind, I see from Tbg's history that he has a Mana Phase 5.
In the Zoeth's defense, it is readily available in the U.S., furniture quality, cheaper than a Mana Phase 5, and quite decent at vibration control using the z-slab shelves, though not the best that can be done. The Zoeth frame design does not follow the Neuance light rigid idea, so Neuance will probably work best with a different support.
I have tried the older Neuance shelves with Zoethecus, with the Neuance sitting on upturned dh cones on top of Zoethecus shelves, and much preferred the Zoethecus z-slabs alone, though this may change with the newer versions of the Neuance that don't need cones. The z-slab/cone/neuance sandwich just isn't the best application of any of the sandwich parts.
As an off-topic point, I'd like to hear a comparison of the Mana performance, with or without supplemental shelves, against Grand Prix stands. It's rare to find anyone in a position to offer this comparison.
