I'd be interested to see some references to some research/measurement
reports that support the above as a generalised assertion about "elliptical
tipped" cartridges.

This is info that goes back to the LP era. Do some googling. You'll
find it. You might try looking for references to stylus shapes intended
for transcription as opposed to everyday use.

Think about the shape of an elliptical stylus... imagine it contacting
the groove a little bit off angle. One side will contact harder than
the other. A conical stylus is symmetrical. It can be a little twisted
one way or the other and it still contacts the groove the same.

Alignment does NOT stay the same. If you use your turntable regularly,
things move around as you handle the tonearm. Elliptical stylii need to
be aligned every three to six months with everyday use.
