Where Have All the 2A3 Amps Gone


2A3 amps seem to have fallen out of favor with designers. Does anyone know why?

I have a 45 SET connected to 101 db / 1W /m speakers and those 2Ws can get loud. But loud is only a small part of what I'm after. I have heard 2A3s on my brand of speaker and loved their magic. They seem to have a huge soundstage and that is what I seek. Plus 2A3s historically have output twice the power of 45s yet 45s seem to be more popular design. I just don't get it.
I was being facetious. I have 45's on 106 speakers and they also can go louder than I need, even on very quiet music. I have not heard 2A3's though I imagine I could like them as well. My other amplifiers are 300B's.
Deja Vu Audio in Virginia sells a 2A3 amp. But I don't know if it's an SET or push-pull. I'll call tomorrow and let ya know what I learn. Keep in mind, I am not associated nor do I profit from plugging Deja Vu Audio.
Isochronism, no problem. I thought you were serious because it seems 45s are more available. But I did find a 2A3 in Virginia. I'll respond back with my findings.
