I have read that it is also more linear and has a wider frequency
response, though those might be a consequence of some of the things you
mentioned.
What I'm hoping for is that someone has done a cascode phasesplitter for
a schoeps circuit that I can copy to get started.
I'm not sure if the benefits will be audible, so I'm looking for real
world experience.
I don't think I know enough to design one from scratch with any
confidence so I'm looking for an example circuit to try first.

A cascode retains the gain of a single FET common-source with the
reduced Miller capacitance of a common-source (voltage-follower).
It opens the range of possible compromises. E.g. it allows using
2SK170 by mitigating its high input capacitance and benefit from its
very low input noise voltage. Or minimizing capacitive loading of a
SDC, thus improving the noise performance.
Ther are some very clever cascode circuits that both bootstrap the
gate-source capacitance and minimize the Miller effect.
