You are correct regarding the need to use advanced stylii, however your statement regarding compliance is an over-simplification.
But most MM are mid or high compliance by default. And most of the vintage MM are high compliance. However, modern MM are mid compliance or even low-ish like Nagaoka. A high compliance cartridge can stay in the groove even on seriously warped records.
I find your frequent reminders about the high level of technology and materials in best-of-class late 70s early 80s mm and mi carts useful btw.
thanks, I am more than happy with those carts.
