Just wanted to post an update. I have decided on a wall-mount solution for the turntable, as i believe that all other solutions are attempts to fix the vibration problem with results that may or may not pan out.
What I mean is that the floor is clearly highly compliant/springy -- so much so that the top of the rack visibly shakes with footfalls -- and is moving vertically as well as horizontally. Bracing the floor from below would definitely help, as would mass-loading the rack and changing the shelving.
However, as good as those solutions may be, I don't think they'll eliminate as much vibration in one fell swoop as doing a wall-mount -- and there could be more time and/or expense involved.
I'm going to see what happens with the wall mount. I have no doubt that all the solutions regarding treating the floor and rack would help with the rest of my system, but I think they're lower priority than dealing with the most sensitive source.
I hope to be in a better position to evaluate my turntable's true performance, as well as that of the rest of the system as soon as the wall mount is in place.
Thank you!
