I experimented with defeating the suspension of the Verdier using macassar ebony footers. These foorters were sourced locally, 2.5 cm dia. x 5 cm tall. They rest on a 1 cm dia. crystal ball and ebony cup. I use a total of six, four at each corner and two near the spindle.
The result sonically is a blacker background, better clarity and smoothness on both ends of the frequencies, and more stable imaging with the soundstage. The width and depth of the soundstage seems unaffected.
I have read in this forum thread from folks who advocate keeping the suspension intact, even for the black MDF plinth version which I own. However, re-reading information on motor control by Thom @thom_at_galibier_design , it seemed to make sense. He is an advocate of tight coupling of motor and platter. And it turns out in my case, I do hear improvement in sound quality. And this is a first step in the road to maybe improving the motor aligning myself with advocates of non-suspended plinth.
I also use an air bearing linear tracking tonearm and often wondered might it not work better on a non-suspended plinth. Again, there are folks who use ET arms on the Verdier although most LT arms, that I know of, are used on the concrete polymer plinth. In any case, I am happy to report that this sound improving tweak is working for me. YMMV
