Plinth mass vs. Foundation mass

In pursuing my analog education, I perused an old thread
on here, a long thread, about Panzerholz plinths.

This thread, along with numerous others, got me to
formulate the following question:

In the general attempt to isolate the platter & cartridge
from vibrations in the rest of the universe, where is the
added mass more/most effective, in the plinth or in the
mounting base ?

I suppose a 100-lb wood plinth sitting upon a 500-lb stone
table would be fairly effective. But what might be a more
"compact" solution ? Is it too subjective to ask where
is the point of diminishing returns ?

Thank you in advance for insights & ruminations.

In my mind (totally un-scientifically validated though) there needs to be mass it the interface of the stylus and the record (e.g. the platter) to minimize any micro resonances that could distort that tiny signal.

Next, mass or non-resonant chacteristics in the plinth and suspension are needed to minimize larger vibrations affecting the signal.

Thirdly, mass in the stand is needed to minimize air-born and floor transmitted vibrations.

You are correct, that ideally you need all 3 to be optimal if you are using a mass loaded design.

There is of course the other camp, using rigid and light designs.
