There are 2 ways to get output from a cartridge over and above the wanted output of the groove. One is spurious vibration via the stylus, the other is vibration of the cartridge body (the bit that should be static) via the headshell.
Cartridge body design and material also influences how much, and the character of, the spurious vibration ending up at the "fixed" part of the transducer too, because it resonates over a range of higher frequencies.
The "standard" cartridge layout is far more influenced by having to be tolerant of poor records than by the requirements of an accurate vibration transducer
It used to be irritating to see so much misunderstanding of dynamics amongst hifi hobbyists and not a few manufacturers back when LP was the prime medium. It doesn't bother me much any more that I hardly use it.
BTW if I gave the impression I thought SME arms were poor it is only in one way. They are just about perfect in every static way. The bearings are in the right place (surprisingly rare) and the balance spot on (also rare). Apart from the high rigidity and low damping keeping the cartridge body less vibration free, which mods could probably fix, they would probably have been my choice of pivoted arm and I would probably have had fun fixing the dynamic shortcomings.
Turntables, arms and cartridges are all ridiculously and unjustifyably expensive to play with nowadays though IMO when modest digital is better in every way.
