Denon was very cheap, what's the budget for new/better cartridge ?
And what is the effective mass of your tonearm ?
Definitely you have to look for cartridges with advanced stylus profile (shibata, line contact, micro ridge, stereohedron ... ), because your denon is conical.
If the budget is under $800 then definitely look for MM or MI
If the budget is over $1k you could find LOMC (but you'be been using MC, maybe it's time for something else ?)
