I myself own a Cadenza Black undergone the same fate.
I have discussed this Cartridge with Third Party Rebuild Services, and have selected a plan for it that I will look to put in place in 2021.
If funds allow it might be a Post COVID Venture.
The Good News for yourself, is that you are assured with your own management of the Cartridge and feel confident the loss of the Stylus is not a result of any user error.
This should give confidence that a retip from a Third Party Cartridge Service would be a valid option to consider.
With the Technician giving the Cartridge a personal attention, there is a further reassurance as to the treatment the Cartridge is to receive.
It is worth a discussion with a Build Service.
I have very recently put a Trans' Proteus UK Based Owner in contact with a US Based Third Party Build Service in NY.
The Proteus Owner has expressed their satisfaction with this option, as the Year Old Cartridge seemed to be a lost cause, but now it has the offer made of the possibility it will function again.
What is not clear is the Guestimate Hours of usage on the Cartridge ?
My experience is that a Cartridge with 'little use' will accumulate micro contaminants that are best removed through a Professional Cleaning.
The more the Cartridge is used, the more the contaminations are collected.
If a retip service is chosen to be used, I would specify a thorough cleaning to be included, I would assume though this is mandatory practice, as the need will be identified at the time of the Cartridge receiving an Inspection.
I would assume you can be supplied a Thoroughly Cleaned and New Stylus Attached Cartridge for approx' $450, if a Third Party Service is used.
