I isolated my turntable from the floor, by mounting it on a shelf attached to the wall.
Wooden floor, brick wall.

I have a specialized TT shelf on the wall. Then i had to put flying burtesses up to stabilize the wall.

Right. Final plan....
Im sticking with my memory foam idea because in my head, it works. I've seen the videos where they place a glass of wine at the edge of the mattress and then jump up and down on the bed and the glass stays put.
There must be something in that.
Sandwiched between 2 pieces of 18mm ply with 4 sorbothane feet (as mentioned above) on the bottom.
That's gotta work! Surely!

Any foam in slab form between a pair of sizeable solid boards will be damn near solid - try it! Its firmness (spring rate if you like) is also non-linear with load and decidedly temperature dependant.
You absolutely need to research Indentation Force Deflection (IFD) if you plan to give it a go.
I've read about a similar setup in a book on making holograms. it was a sandwich of three stiff boards (granite, stone or similar countertop-type material), with two layers of large inner tubes (the size once used for automobile tires) in between. The two 'sandwiches' were each tuned to a different frequency by board weight and/or tube air pressure, so a large range of frequencies are absorbed.
Roughly, you want the support to be compliant with a resonant frequency under 11hz. If you want it to work you need to do some load vs spring rate math.
Most of the stuff suggested won't get anywhere near this low.

Honestly mate, I just want the tt to not be directly on the ikea kallax unit as it is at the moment.
A simple bit of isolation to make it "better than it is" is all I'm after.
Appreciate the advice though.
