The cutting issue is not the frequency response of the cutter head, it's the amplitude limitations at high frequencies caused by the power input needed to cut those cymbal crashes. Since the RIAA equalization significantly increases the recorded levels.Again, on the bass end, it's not frequency response, (cartridges respond to record warps)it's the amplitude limitations of what can be recorded and tracked. While it was an extreme case, do you recall the recording of the 1812 Overture with the huge canon shots back in the late 70's? The groove spacing was opened up dramatically to fit this groove onto the LP. Very few cartridges could track it, and the few that could were all ultra-high compliance MM models. To a lesser extent, bass is generally cut back on loud passages to allow tracking with average quality equipment. This also gets into the issue of the compliance of the very expensive MC cartridges. My information is admittedly out of date, but last time I looked, most MC carts had only moderate compliance.
Follow Ups:
You are talking about the Telarc 1812. I have the record and my Sure M97xe/Grace 707/LP12 tracks it with no problem.
So did my Shure M95HE in a modified Dual 1229. An ADC XLM and a Pickering XV-4500 did also, but none of my AT's would, and none of my Ortofons.
I'm not suprised about any of the cartridges listed that did track it. I'm suprised that the AT's would not. I sold the Precept line and the MM cartridges tracked fine (at the maximum recommended tracking force of 1.5 grams).
