Dear @pops : I posted about MM cartridges because you ask for but in reality you own two LOMC cartridges that can't be outperformed by MM ones.
I owned the Jubilee and owned the the Transfiguration Temper and Phoenix S and listened the Proteus that is excellent performer.
To fix both great cartridges is the best alternative if you want that high quality level performance.
Other than SS exist other rettipers as Van den Hul or Northwest Analogue ( https://www.northwestanalogue.com/cartridge-repairs.html )
or Expert Stylus and some others out there. So you have option about.
Regards and enjoy the MUSIC NOT DISTORTIONS,
R.
