I am new to tubes, but my experience so far with my Prima Luna amps (a Dialogue 4 and a Dialogue 7) is similar to Dover's. In triode, in my system, the PL's seem to lose resolution and dynamics. And the bass becomes less defined, even with my speakers crossed over at 80Hz into a sub.
It must be system dependent, because I've heard the PL's several times at shows, and I always preferred triode. But here at home, ultralinear is the clear winner.
