I’ve seen what you’re talking about but the issue was the wrong springs and they weren’t loaded correctly. If you’re touching the table and it shakes you have a dampening issue. There is no shock absorber or accumulator.
A spring will bounce, that is what they do. The correct pod and being adjusted correctly, won’t. (I should say shouldn’t) something is wrong.
After building as many heavy plinths for TT as I’ve built you got a GUMMY PUFFER issue..:-) (Spring dampeners). Thorens will wobble all over when they go bad.. Gummy Puffers.. The 30 to 200 lb plinths I build for Thoren, Russco, Garrard, Sparta, Fairchild, EMT, Roberts. Transcription and Broadcast TTs. Have springs and not the least bit touchy..
I may anchor the TT to the plinth but the plinth gets springs and dampeners or the mechanical noise would go through the roof. It’s just TT 101..
Air or a mag lift platter is a step up for vertical isolation, but you still have a horizonal issue because the bushing and spindle still touch..
A standard 3.5" concrete slab is like a trampoline.. You really want dampening and decoupling there if it’s on a soil bed.. A couple million pound Rock face would be a good starting place if you want solid..
There is no such thing as solid.. A life time of anchoring STUFF.. It just moves..
