I’ll probably try exploring the world of SUTs, but just out of curiosity, what SS phono stage in my price range do you really love?
Now definitely current injection type of the phono stages like 47 Labs Phonocube for MC only, your LOMC must be low impedance like 2-5 Ohm. I bought it not so long ago (used, not new) at your price range, prior to that i've been using (and still have it) the JLTi mk4, the mk5 now available here.
Regarding the SUT i like vintage Luxman toroidal silver SUT combo.
