Question for Van Alstine hybrid amp owners

His recent FET-valve hybrid amps employ 12AT7 tubes for the voltage gain stage. My experience with 12AT7 tubes (even NOS) in Llano Trinity amps has been that they are a bit rough in the upper mids, and not as "musical" as 12AX7 or 6922 types. But of course that could just be the Llano context. Do any VA amp owners have comments on this concern about his use of 12AT7?

In my experience, VA amp FET 350EX isn´t the most extended on highs, but its upper mids aren´t rough at all.
They are not very sensitive to tube rolling, you might use standard tubes and the sound is very very close to NOS.
If you like the amps, I wouldn´t worry about being rough. These amps are very musical, maybe not the last word in hiend virtues, they just make music for an affordable price.
IMHO
