What Mijostyn said.
Also, there is no reason to think you must have an MC cartridge in order to realize your goals. There are any number of MM and especially MI cartridges (e.g., Grado, Nagaoka, SoundSmith) in the same price range as the MCs you are considering (or cheaper) that would be an improvement over what you are now listening to.
Elliot, I hope and trust you have come through your medical ordeal and are now in good shape. Glad to know it.
