By the way- some science I did circa 2007 or so.. I used a sweep generator, a speaker coil, a transducer, and an oscilloscope to measure the isolation of various “audiophile” turntable isolation products and techniques. Sorbothane, neoprene, spikes, ball bearings, etc etc.
Best solution was also the cheapest- a “double yellow dot” squash ball and a 1/8” thick, 3/4” ID nitrile hose washer.
You can get a case for like 20 bucks. This is how I can play Prodigy and Crystal Method with a subwoofer and not have a needle skip. Enjoy!

A quick note on the turntable platform - I use a piece of granite, since it's basically free in this area of the world. Granite has wonderful mass and is also quite stiff, but it will "ring" if it's not damped. You can affix some dynamat or something to the bottom, that's probably already plenty. If you're insane like me, find yourself a piece of Aluminum Composite Panel (ACP), and bond that to the bottom creating a constrained layer damper with different density materials to avoid resonances in the audio spectrum. You can't see it at all.
