Vibration Issues / Turntable Decisions

I already acknowledged some racks and stands are not too bad. And I never mentioned anything about damping. I trust you aren't confusing isolation with damping.

I said decoupling, not damping.

Fixing the deflection in the floor from underneath is not that difficult, its the choice that requires a bit more effort in a shorter time span physically ,but it is THE only choice that  removes the problem.
All others are band aids that somewhat work at varying degrees , and at differing degrees should you change the table or the rack.
A solid foundation will always give better results and cost less and take less time to do where access is available,  than the hours of work it takes to earn to save for an inflated , retail band aid to solve an easily solvable problem, not solved at all but just masked with band aids.
No brainer for me, a Saturday morning and its over, free to have any table, rack or speaker, stand mount or not with greater choice on design and function and cost.

Yep, 100% right on. Going to take some time this weekend and investigate some options under the crawl. I only have 2' of working space between the bottom of the floor joists and the earth below.

Stay tuned!

I was responding to the poster previous to my comment. I am pro decoupling and pro draining and to a lesser extent pro damping. In combination, not separately.
