Suggestions for next cartridge...

I’m currently running a Kiseki Purpleheart. I’ve also tried the Audio Technica ART 9, Dynavector (forgot which 20X model moving coil), Ortofon 2m Black--all of those extensively and in the recent past.

When it’s time to add a new cart, what do you recommend I try? Phono preampfification is solid (Manley or Doge) and my table is a Technics 1200 GAE. I have efficient speakers (Cornwall IV) and all tube system.

I could be happy with a rebuild on the Kiseki, going back to the ART 9, but who doesn’t want to try something new? 

I enjoy the analog tape like quality of the Purpleheart.  It's lush and has some sweetness.  The ART9 was incredibly neutral top to bottom.  Arguably, it was a touch dry sounding yet accurate and dynamic.  The Dynavector sound escapes me a bit as I haven't had it here in 3 years.  The 2m black was big and bold, but could have used a bit more air and detail.  All have been great.

Budget $1k - $5k (as we move higher the purchase needs to be planned out more).

On my current shortlist are: 

Audio Technica ART 1000
Hana Umami
Lyra

Thanks for you thoughts!

What should I try and why do you like it/recommend it?
