Yeah, huge amount of high end audio sounds great in theory only to completely fall apart in practice. Like cartridges, the suspension should just get all hard and brittle and go to hell just sitting there used or not. But this never seems to happen. The Stanton 681EEE on my Technics from 1976 still works great, and that is a lot older and a lot cheaper than your Clearaudio.
A good cartridge is like a good watch. Sure they will tell you it needs regular service. But in reality, If it ain't broke....
