@three_easy_paymentsorks fine with cartridges in the .5 mv range and the right SUT
I guess it just wouldn't work with my Zesto SUT which i thought was pretty versatile. Mine only adds a max of 22dB gain. I know you can get SUTs with much higher gain options. My Luxman phono stage goes up to 40dB on MM so I can get up to 62dB gain with the SUT. Around 59dB is what seems to work best with my 0.5mv cart.
Now I see how people become SUT collectors. ;-)
