VPI Scout or GEM Dandy PolyTable

What's under the crawl space?

If you can wedge something between your stand and wall to give it a secondary place to rest against it will stabilize it further.

It sounds like you have done a nice job of modding and updating your table. A bit of dynamat placed on the chassis would be the next logical move. Correct me, but I don't think you can't adjust the VTA with the 202? If you find a 250 you can get a Michell VTA system, which is not expensive.

Also, upgrade the tone arm cable would be a good idea.

You are about 85% as far as you can go with the table. Might as well go the rest of the way. 

@raymonda
No VTA Adjustment.
Forget, also have done a Cardas cable upgrade to the tonearm cable.
I’ll take a look at tonearm options.

@mb1audio02 just a vapor barrier and earth. I am on 2x14 floor joists every 12’

If your VTA is good you can just shim it in the future, if you replace the cartridge. The rewiring is another smart move on your part.

Ok, so regarding the bouncy floor... what about throwing something like a Mapleshade or Ginkgo Cloud platform under the Thorens?
