What's under YOUR turntable?


You're very welcome to be as informative as you wish.
(My apologies for borrowing on a similarly* titled thread in the Digital Forum.)

Worthwhile upgrade using Sound Organization wall mount TT platform. Heybrook TT2, Linn Ekos, Clearaudio cart.
four (obviously dry) kitchen sponges. Really. On a 3/4" MDF shelf in a large CWD stand. I may have lucked out with the right mix of materials, but it makes a difference: no acoustic or structural feedback, and greater bump resistance. It helps that this is a concrete slab townhouse floor, and the turntable itself is filled with 10+ lbs of inert clay, as well as having excellent suspension of its own. I can't say sonics wouldn't improve with some megabuck stand beneath it...
A slab of 1/2" acrylic suspended by four double runs of 10 lb. test fishing line attached to a 3/4" slab of plywood over the rafters in the attic. Until I mounted it this way, I could never get my Oracle Delphi Mk.2 to bounce straight up and down perfectly. Now it does and the platform goes with it, but at about half the amplitude of the subchassis. The sound improvement over sitting on a pressboard cabinet was huge. It was the best tweak I ever did. After I drilled the holes in the ceiling, I plastered right up to the fishing line so it appears that the line is glued to the ceiling.
