If you've owned MANY types of amps, I need your suggestion:

That's why I mentioned Bad Cat. That is where Mark went to design some amps plus the Hot Cat IMHO is really versatile. I have the Hot Cat 15 NR in a 1x12 combo and the amp kills on the clean and dirt fronts. Also built as solid as a rock and Bad Cat has great customer service. Not dissing on Matchless just saying. Fargen has some great offerings too and you could get a custom shop with clean/dirt channels.

Just beat me to it, Bogner Shiva, EL34 version
Some say it's the best "pure tone" amp ever

Great amp!!!

I have the 20th (KT88) version, I'd say it's pretty much the amp you described you're looking for.
