What cartridge on your VPI prime?


I own a VPI prime, I installed a denon 103 R and I had never change the cart due to lack of funds. Now I want to upgrade my analog ring to the same level of my digital.
I have been considering based on reviews.

1- ortofon quintet
2- charisma MC2
3-ortofon black
4-kiseki blue.
5- rega alpheta 2.

I would appreciate any inputs from your end about cartridge selection and phono associated currently I am using graham slee reflex M.
Kind regards and thank you.

Thanks for chiming in HW!
Perhaps you could provide some more detail about the Prime line.
A friend told me that during a recent visit to your VPI site there was work being done on a Prime Signature turntable.
Any truth to this rumor? Any hints about the upgrades? Will the standard Prime be able to be upgraded to Signature status?

Cheers,
John
Just recently added an Ortofon Cadenza Bronze to my Prime. First cart was a Soundsmith VPI Zephyr that I moved over from my Scout. Zephyr was great, Cadenza Bronze is greater.
Mountainsong.....I just bought my Winfield for 3000 dollars....you can too if you check around. I needed to replace my Benz LPS...it was getting long in the tooth.....the Windfield is a viable replacement.  It needs careful setup..can sound very good to great depending how you install it.  It takes a L-O-N-G time to break in but is very interesting to hear it improve.  Recommended.
How is the VAS Nova sound related to the ortofon Quintet and Charisma MC2?
Guys I really appreciate the time you are putting into this discussion.
