Why not forget about loading and go
with a Sutherland Phono Loco current/transimpedence phono stage?
At $8200 it’s right at your budget
i personally went through several voltage type phono stages
until I personally went with the Little Loco
This change was the single largest improvement I have ver experienced in gear changes /upgrades To my vinyl front end playback.No longer do I need to worry a loading and this unit gives me the most accurate reproduction of the grooves that I have ever experienced. Also forget about hum because this design is dead quiet.
Good luck Willy-T
