The Moth 2A3 is probably similar to the EC 2A3 in some ways, however it's going to be in another league in others. Moth Audio was more about making no-holds-barred one-offs and so they went all out in parts. The newer EC stuff is good no doubt, but Craig wants to keep costs down, so the parts are going to not be nearly as fancy. That's not to knock the newer stuff, just to say the priorities are different.
You could always ask to up the output transformers and volume pot :) If only Craig would also offer upgrade option on the other parts too that would be perfect :)
