If you need a cartridge with fixed stylus/cantilever that you can’t replaceable yourself then buy a Low Output MC cartridge. Any MC cartridge can be refurbished or replaced by the manufacturer or some re-tipper. This is time consuming, often very expensive and inconvenient.
The benefit of MM and MI is user friendly stylus replacement that can be purchased anytime without sending your cartridge anywhere. Normally we have spare styli for our MM or MI carts and trust me (I have many LOMC too) that life is much easier with MM/MI and sound quality of the best MM/MI is outstanding. I could easily live with MM (without any MC), but I want to have all types of cartridges (including Moving Flux).
