Phono stage upgrade


It is the tine to upgrade my phono stage. For the first year of comeback in vinyl I used a heavy modded NAD 1130. For its price ($200) it is superb. Now, I would like to try something else.

My budget is $600 (including the power supply).

My cartridge is an Ortofon Super OM40 (MM).

What is in your opinion the best (used) phonostage under $600 for Moving magnet?

Thank you for your help.

Wright WPP 100 or 200 if you can find a used one. Hard to find used because most people keep them. I think they are $825, new
Graham Slee Era Gold Mark V: especially good synergy with Hadcock arm and Music Maker cartridge.
Second the vote for the Dynavector p75....I feel I would have to spend almost three times as much to get something materially better
Thank you all. I got a John Linsley Hood phono stage, built by Williams Hart. Linsley Hood dedicated his life to circuitry design (1969-2004), and his books are highly regarded by all important designers. A phono stage build by a guru in a vinyl lovers country? - WOW!!!
