Outstanding, Congrats!!
Is Craig Uther making more of those 2A3's? Many have posted that that was the best 2A3 amp they had ever heard. I think you are in for a real treat, from the sound of it. Please post a pic of the new amp.
Meantime, the reports on the new speaker are uniformly highly, highly positive. Great review on American Wired. Congrats to Louis, there, for hitting yet another bullseye.
