I'm not talking cart and tonearm matching, rather assuming the user knows how to do that and has the options to take advantage of either. Also lets disregard the issue of dampening with a stabilizer brush or fluid-filled tonearm base.

I realize that a great many Moving Coil designs are mid to low compliance, though the exact reasons for this are a mystery to me.

I also realize that lower compliance makes cantilever rigidity more important due to the required downforces, which may necessitate more exotic materials to get effective tip mass down to minimize high frequency mistracking and FIM distortion on loud records.

I also get that measuring loud treble mistracking and FIM distortion is difficult due to various harmonics involved, such that a cart that tests perfectly on one test record can still have issues that are audible in other ways on loud pressings.

Any benefits between high mass/low compliance compared to low mass/high compliance other than this? Any links you know about? You gurus with any inside info, post away. Thanks.
