I would keep that TT, and add additional uni-pivot arm wands, with alternate cartridges ready to go. Jazz: there are lots of excellent sounding Mono LPs when so many of the greats made their reputations, so an arm wand with mono cartridge ready to go. Existing cartridge if it has some life in it.
MC cartridge (do you have MC phono stage set up? If not, a SUT with PASS for MM and a few inputs and x factor adjustments will set you up for future choices.
I chose a vintage Fidelity Research FRT-4 for that reason, there are Entre 100’s I think, others that members here know about.
