Cartridge advice in the $2000 range

Call me ignorant but...
What has you firmly convinced that you need a new cartridge??

You have an EXTRAORDINARY tonearm!! Count yourself extremely fortunate.
I'm not a Nottingham fan. Your existing cartridge is probably fine. Sell the Nottingham and use the money towards a Raven or if need be a Baby Raven. OR perhaps a better TT stand. OR perhaps better matching for your existing cart - if it is also an MC type.

What speakers are you using?
What Preamp?
What amp(s)?

If you REALLY need a new cartridge... IMHO, at much less loot, a LYRA Argo i, Dorian or a Soundsmith re-do is probably more cartridge than most systems can resolve.
My prediction is that what you are seeking lies in upgrading other parts of your system.

ortofon jubilee floats my boat...read the reviews I would have to agree with them, does everything very well.

The rest of my system is Kubala Expression wiring and Merlin Vsm Mx speakers. The stylus on my cartridge was ripped off (i.e. cleaned) by my cleaning lady.
BTW, I am thinking about a Raven One.

Another without reservation endorsement of the ZYX Airy 3. Superb.
