Ortofon SPU Meister Silver MKII like cartridge to fit a Kuzma tonearm

THE SPU NE is closer than the Royal N.
both want a tonearm with an effective mass of over 18g.
The NE has an output of 0.2mV and an internal resistance of 2Ω
The silver has an output of 0.3mV and an internal resistance of 3Ω
The Royal N has an output of 0.2mV and an internal resistance of 7Ω
This latter figure precludes the use of a 1:30 SUT into a 47kΩ MM phonostage for the Royal but this is a decent match for the other two. Put the Royal into a 1:20 SUT or an active phonostage and it can show its worth.
I’ve been using a Royal on a Schröder Reference into a Naim Superline loaded with 220Ω for the last year and love it. It is rather too sensitive to VTA/VTF and can sound rather lack lustre if they’re not just so.

I loved my Royal G mkII with Replicant-100 stylus profile. 
I also enjoyed SPU Spirit (limited edition model) with Elliptical profile, my sample was number 500 (and only 500 were made).  

Miyajima is much more interesting low compliance cartridge than SPU, mainly because of the unique cross coil method (Miyajima patent). The Miyajima is the most organic MC cartridge I have ever heard! Highly recommended.  

My recommendation is ZYX Ultimate 100 H. In my setup is was
very close to the SPU sound.

very strange, modern ZYX Airy III and Premium 4D were both completely different from any Ortofon SPU (I owned 3 different models) in my system. ZYX was a high resolution cartridge with MicroRidge profile while the SPU is not a high resolution cartridge with its Conical or Elliptical tip (exceept for the Royal GM with Replicant 100 stylus which is a high resolution).
