What happens when the stylus tip wears out on a $12,000 cartridge?

Not one idea that will be proposed by the average thinker for a MC Cart' to have a simplistic exchangeable Cantilever/Styli assembly will be one would be Cart' owner friendly as is the MM methodology for C'lever/Styli exchanges.

The designs I see that can be put on the table by 'Mr Average Thinker', are ones   that would have the need of a professional technician to carry the procedure, as being invasive of the very very fragile assembly is unavoidable in a typical MC design needing a new part?

A design that has low man hour needs to complete the exchange and the notion that fragile parts are much more protected from associated risks for being damaged, might? make the idea of having a Cart' with easier to exchange C'lever / Styli as an attractive option for learning and assessment about materials effects on changes to produced sound produced with differing materials used for the assembly at this interface.

Being myself an 'Mr Average Thinker', I can't see much more value to attempting to carry out such a design. 

In the hey day of MM, it was not uncommon and at the present still here but less common, to see off the shelf parts as a C'lever / Styli assembly, that is using different materials from those selected by the OEM for certain MM Cart's.

@pindac I think you are suggesting MC cartridges might be made with interchangeable stylus/cantilever assemblies? And you would make it simple and perhaps not require a technician? How would you suggest getting around the stumbling block of the connections between the coils on the proximal end of the cantilever and the output pins?

As stated " I am Mr Average Thinker ' on such a Subject. 

I have 'thought' about the Cantilever to Armature Interface being a mechanical coupling being one that is not dependent on adhesive and be a coupling that is more in relation as a coupling, that is similar to the micro mechanics found in certain watch designs.

I don't see any further need to flog to death, this very basic idea.

Sounds like I have to stretch out my use of my Koetsu Stone cartridge. Also not sure if they can retip my diamond cantilever in my Corralstone D.
