What MC cart would you use with this setup?


Greetings!
Looking for an MC cart recommendation - I love my Ortofon 2m Bronze MM, (love the detail and tone) and the stylus will be wearing out in the not too distant future. I may replace the stylus with the same or try the Shibata(black). 

My only foray into MC is a Denon 103R and after messing around with the loading/gain switches on the phono stage, it's not bad, but doesn't sound as nice as the Ortofon. Considering a Dynavector 20x2 L. I understand the really nice MC can be very costly. I'm not afraid to spend some money, but don't want to get too crazy if I don't have to, to get something that may match or rival my Ortofon. 

My setup is a Rega RP1 with upgrades: 
Rega 24v motor upgrade
Rega RB808 tonearm
Groovetracer reference subplatter
Groovetracer acrylic platter
Rega Aria MM/MC phono
Primaluna Dialogue tube preamp
Bel Canto REF500 mono-blocks
Magnepan 1.7i speakers
Klipsch Reference 10" powered sub

Recommendations on an MC cart for this setup would be most helpful, thanks for any advice! I realize how subjective this can be, but all the same, I appreciate your thoughts.

The AT-33PTG/II its out of production but are still available at a reasonable price. It has a Shibata stylus.
since you like the 2m Bronze, why not go for the Cadenza bronze?   Another alternative is to send your 103R to Soundsmith for a ruby cantilever / line contact stylus refit.  I have personally tried both of these.
Thanks everyone for the recommendations, I'm not familiar with a few of the cartridges you mentioned, so will be checking those out!

Noromance - when you say I need a better turntable, is it because of the plinth? (everything else has been upgraded...the RB808 tonearm, etc.)
