Cartridge upgrade????

Ok so finally I am at a good place with my Kuzma Stab S-12 using a wonderful Hana SL cartridge fed into Bent Audi Sut to Sutherland PHd3...into my amplifier. I think it really sounds good but got an itch to maybe upgrade to a higher end MC cartridge.

I was considering the Air-Tight PC 7 but not really sure if it is worth it to spend all the $$, or maybe an Ortofon Cadenza  or????

Anyone have experience moving up from the Hana SL, and if so may I ask to what? No need to do it in a hurry but thinking that maybe this would be a good path, and mostly I am listening to jazz...lots of horns and small trios.

thank you all in advance....
