Yes to all of the above. I do not know why the manufacturer designed the speakers as he did. He uses them primarily with conventional tube amps (Dodd's)with transformers. But also, they would work just fine with solid-state amps as well.
You're right about x-over changes. We did measure the strings individually and together. Despite the x-over being 3rd order, all it took was the change of one capacitor and we achieved a very good acoustic response. Better to be lucky than smart, says Confucious.
We are going to experiment with a whole new x-over with first-order slopes. According to BG, this will not hurt the tweets any, even at 300 Hz, versus the 850Hz we have now. Anyway, we can put it back if we don't like it.
Cheers,
Chuck
BTW, Lew, I believe I passed on the news that Lou Johnson had passed away. Imagine my shock when I bumped right into him coming off the elevator at the Venetian at CES last week. Rumors to the contrary, etc.

Very interesting , I have Di Capo i's . Do you like the way they sound with the big OTL's ? Do you find that the Auto-formers effect the sound or have a flavor ? Have you ever tried the Di Capo's with an SET ?
I know some have used SET"s and say it works . But as Ralph iterated , how much of the true SET sound is heard if one must crank them up passed the 20% point .
I didn't care for the sound of the De Capos with the Autoformers. The sound was "bloated" and overly full. I love the way they sound fed directly out of the MA-1s.
I've not tried an SET, as I don't have easy access to a quality amp.
