Soundsmith Zephyr MIMC upgrade to Paua opinions?

I have a Soundsmith Zephyr MIMC mounted in a Basis Vector 4 arm on a refurbed Technics SP-10 MK II...With the blow out pricing on the older SS cartridges going on now, I am considering getting a Paua MK I. Has anyone heard these two or made this upgrade to say what are the performance differences between these cartridges? You can getthe Paua for $1999 at online retailers..that is what has me thinking...I have been ripping vinyl to DSD128 with the Korg DS-DAC10R (on 50-ish albums so far)

BTW - the rest of my system ...Tom Tutay tube phono, Tube Research Dude pre,  Tube Research Samson monos,Greem Mountain C3-HX, two Seaton Submersive HP Subs, Lumin A1.
