I have a MC headamp project that I wanted to share. It was inspired by the Counterpoint SA-2, which is a very good piece, from what Ive read. It has outstanding specs for an all tube setup, the measured noise figure is around 93dB which is somewhat hard to believe, but there it is!
I think I can get very close if not better, at least from the PS. The signal stage is a grounded grid, mu-follower topology, which should give me a good PSRR figure. I was able to get good results too in breadboarding and testing.
