If one wants to remove audible rumble one can simply start by
getting a tuntable that doesn't suffer from this problem as does
Arny's table..

There ain't no such thing if you use a turntable instead of the
funny-sounding thing that sockpuppet wheel mentioned.

How many db down does rumble have to be to
be inaudible?

Depends on its spectral content. However, the best turntable in the world
won't reduce well-known sources of low frequency noise in LPs, such as
"grain noise" and rumble from the cutting lathe.

Don't obfuscate. We're talking turntable rumble. Can turntable
induced rumble be below audible levels? We both know the answer is
yes.
