I’m no cartridge expert.... Is it even possible to build a MC cartridge with a removable stylus like MM’s? I’m guessing not or there would be plenty out there. I recentlu learned that early Ortofon Concordes were MC. Who knew
Anything's possible, but practicality is another matter. There's no natural air gap to serve as an easy separation point like with MM or MI. An MC is literally hardwired from stylus tip to lead outs - where every micrometer is incredibly delicate. You could create separation ability with custom contacts, but where? Anywhere before the coil is too delicate and would add too much moving mass, negating the performance of an MC. After the coil, and what's the point? You're replacing the most expensive parts of the cartridge right there, so economically it's not viable, and probably sacrificing some alignment tolerances too.
