now, your question:
To get a preamp for both line level inputs (how many inputs do you need?)
and MM/MC phono stage
and multiple loading options for MC
is rare.
I decided to get a SUT step up transformer, with PASS for MM, and a few loading options for MC, and 3 inputs for 3 different arms.
That lets you get a preamp with MM Phono and Line Inputs, you send the SUT's output to the MM Phono input.
lots exist, I chose this one (this one is expensive but shows it well)
