Bigger and heavier doesn't necessarily mean better. Within a specific design that relies on mass to iron our speed inflections due to the pole switching on a motor then yes. Likewise that same platter can in facts absorb spurious resonance.
However the EMT 950 has a very light plinth something like 200 grams - the logic and their analogy is that the platter is like a sports car driving up a hill overcoming corners etc. as such a light weight is better able to overcome those ripples. That said the plinth/frame weights a ton and it has incredible speed control.
Then there is the Grand Prix and Rega Naid which are both designs based on low energy storage using intelligent speed controls to overcome speed ripple effects.
My point is that bigger is not necessarily better. It's about implementation and the overall design. Think of it like food - just saying adding sugar improves the flavour - no good if you are eating lamb chops or steak.
