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.  ;-)
