James, you need friends (audiophiles) in real life or dealers who can loan you gear to try. Remember that your line level preamp also have gain (if it’s not passive). When you add SUT you connect it to MM input. Headamp can ne better than SUT, for example ZYX CPP-1 headamp is agood alternative to any SUT.
I prefer solid state phono stages, tubes are noisy, microphonic and they do not last forever. I can’t recommend tube phono stages.
