I haven’t got through all the information in replies yet, but I will add this. My C 22 is an original C 22. I used to have a Audio AN S2 L step up transformer but I got so tired with grounding issues with the vintage gear that I just sold it And decided to go MC phono stage. I have a digital meridian set up coming soon that I will need a phono-stage for anyways. The Audio Note / Koetsu will end up with the Meridian and my TD 124 with a Grace MM F9 will end up with the C 22 and Mac gear.
I am using a cheap little project phono box with MC to make it work at the moment
