I'm consolidating this good advice so that I can retrieve it later this year (when I have more disposable income). Thanks, eh.
Here is my understanding from what guys over on the Lyr thread have said.
-- 6N3P from the 50's (Foton triple mica) are the holy grail. Apparently, the 2x mica will suffice in a pinch, but are a little less good.
-- The 6N2P is a decent tube for the price (needs no adapter too). No one ever really broke down the best of the best 6N2P, but safe to say the older the better. 50s if ya can. I didn't love them in the Lyr, I thought their sound stage came off as really disjointed. Sounded decent in the Music Hall 25.3 DAC I have though, but I felt like something was MISSING all the time. Decent response across the spectrum, but just felt a little lifeless. Really cheap though.
-- 6N1P is regarded as being ehh by most I have talked to. Decent, but I have heard some say it is kind of gritty. I would agree. I had one in my Vali for a while. I thought I liked it, but compared to the 6N2Ps I have (and they are bad ones apparently, 1976 triple mica Voshkod) I would rate it lower. 6N2P lacks a lot still but is definitely smoother.
Honestly, IMHO recently I have started to like the National branded Matsu "mullard" (Japanses) 7DJ8/PCC88. I really hated it at first honestly, but now I like it a lot at least in the Lyr with the HE 400I. Isn't warm like a Mullard, but has a really clean presentation with basically no noise. A little warmth in the midrange feels kind of fluid. A good buy if you can find one, great for a sub $30 tube. Upscale has them for a little more, that's where mine are from. I dropped my 58 bugle boys for them.
Consolidating my consolidation. Good intel. Thanks.
