What separate tube phono stage do you use ?

+1 on the recommendation for Croft.  I'm using a Pear Audio Classic Phono, designed and built by Glenn Croft.  It's easily the best sounding MM phono preamp I have ever owned and it plays nicely with all of my SUTs for MC needs.

I would be using MMs for the foreseeable future, good ones. Croft/ Pear Audio, that's interesting, they make excellent turntables - reincarnation of Nottingham. I have Nottingham, by the way.

Do a search of NVO (New Valve Order) a small company from Cyprus competes with the big boys.

Greek part of Cyprus or Turkish ?

Eastern Electric Minimax Phono Stage is worth checking out.
