the MMC6000 have some kind of special Shibata stylus right, so probably more sensitive to misalignment then a more basic elliptical, but enable better tracing of high frequencies (if that’s still valid to expect from a used 40+ year old cartridge).
I don’t care about quadraphonic audio but would try to find a Beomaster 6000 4Ch just because it would look cool together with the 4002, same aesthetics. The two best looking B&O units in my opinion.
