Ecclectique,
How long did you leave the EH6SN7s in? I thought they were berry, berry good right out of the box, but they really bloomed after a month.
I have numerous NOS 6SN7s: Tung-Sol Round Plates, 52 Syls, etc. among others and I prefer the EHs to all of them. They really came into their own after a hundred hours or so (I'm just guessing here, but they did take quite some time to really become outstanding.)
I know you are far more experienced than I am when it comes to tubes, but I thought I would just offer you my experience.
