@lewm I am off the opinion it is not too many years before I hang up the gloves for the use of MC's. The design in my view will not be offering much more over an MM or others to be put to use, as my level of hearing will be deteriorating.
At present I have a range of MM's to bring back into regular use and the Ceramic Cart' has got about £50 tied up in it inclusive of the spare stylus, which will supply a very good investigation and experience for the outlays I have made. I have spent on quite a few occasions, more than £50 on unknown devices, just to see how they perform as a interface, and have kept them available for demo' and loan purposes even if not proving to be to my preference. Tube Rolling is just one experience, Platter Mats another, along with numerous Cables.
The intention to do more to the Cart' and include a Boron Armature and Replacement Tip, will be the where the bulk of costs are to be associated. That is the cost to experience this Cart' as a bespoke design and to be produced as a build type that I would like experience.
