It's a coke bottle Mullard EF37A - in my estimation, the very best of the 6J7 equivalents!

Yes this is true! Although to be honest I am now running it with 1940s metal RCA 6J7 tubes and prefer their sound slightly.
I am glad I dusted this thing off and gave it some attention, I had no idea that such good sound was right under my nose all along. Now I finally see how you "crazy" SET guys can be perfectly satisfied with such low power! I don't understand the why it works though, objectively this shouldn't be happening.

Well, let's see.
Because you are most likely within the reverberant field and that field starts no more than 3 feet from the speaker, with 2 watts into a 90db speaker that speaker will give 93db spl at the listening position (or anywhere in the room beyond where the reverberant field starts).
There are 2 speakers in the room each receiving 2 watts and each producing 93db spl, that gives you 96db.
96db is really loud.
I would say, objectively, it should be happening.

I didn't define "it" :)
What I am referring to is the quantity of information my system is now delivering to my ears, it's like I went from 480p to full HD, using an amplifier which has higher distortion, almost no headroom to speak of, and a rolled off top end.
I'm sorry. I thought the "it" was the SPL's you are able to get.
Never mind.
