Jon, thank you for your efforts leading to this speaker, they paid off, Danny has a winner..... I was listening to Steve Miller Fly Like an Eagle, total immersion into the music, it was as if the music was coming from nothing, difficult to explain. My wife walked by, I called her in to sit in my chair, she resisted, she has no interest in this stuff. She relented, I played the same track, she started grinning, by the end she had a big smile on her face, I asked her where the music was coming from, she said, everywhere. When I finally got my chair back

I moved from Steve Miller to Steely Dan Deacon Blues, same thing, amazing soundstage, enveloped by the music.
I have never heard anything quite like this. It is still very early in the breakin of these speakers but they are really impressing me so far.
With regard to volume, I am driving them with 3.5 watts of Bottlehead 2A3 goodness high passed at about 150 Hz. In my small room they effortlessly go louder than I would listen typically and as loud I would go when really jamming. I am looking forward to more listening.
I hope this doesn't come off as over the top, it is what I am hearing.
