I do love to romanticize about a sweet 300B, 2A3, or 845 amp, and I keep saying I'll end up with one.....but we'll see. I love my Aric Audio "Push Pull" EL34 amp, and will die with it.
For years I've have a Bob Latino Tubes4hifi ST-120 amp that can run in "triode" or "ultralinear" mode. It's a $2,000 amp including tubes, and I just don't give it enough credit; it's a little brilliant amp. It responds really really well to tube rolling too.
