Modjeski says Yes! to 6DJ8 for audio

I'm finding this to be very interesting reading.

Modjeski has been looking at tubes for a long time, admits he made some mistakes, but likes the 6DJ8 (actually, russian 6922 because they are the real thing) for line level audio, argues they are more linear in actual use due to high Gm, work nicely in cascades with much higher bandwidth than 12AX7, stay away from high specified dissipation specified and they last well.

And he tells an interesting story, making a lot of points I had never thought of, best explanation of Gm and mu and why Gm is more important, can't trust published curves, etc.
