Basic anti vibration? Cones vs pods? Is there "good enough solution"?

New to this part of high end audio. Cones (stability) vs "cushioning" (e.g. pods) Different schools of thought? Do most people use combinations of both? Trying to understand (if possible).

I’ve read recent threads but don’t have the energy to test zillions of combinations. Is there no "this will probably be pretty good?" e.g. I did online research and upgraded to prima luna tube preamp and parasound amp which are good enough for my purposes (at least now).  Also 100 lbs floor standing speakers.

e.g. rack with shelves made of granite "bonded to a 3/4 inch thick anti-resonant substrate"
