There is no one "best" ss or tube or whathaveyou amplifier. You have to consider which "horse" you're riding on which "course". IME DAG is certainly a worthy option among many.
I've been listening to a D'agostino S250 in my system for the last month, after using a Luxman M900u for a year. The DAG does have some outstanding qualities that could match the certain speakers/systems/rooms/tastes just right. It portrays a beautiful midrange that is simply mesmerizing - - fully fleshed out, 3D palpability. It definitely comes from a "bass-weighted" voice, which works quite well with my TAD CR-1's, but may not with speakers that are already voiced a bit "richer". Even with it's richer voice, the DAG digs deeply into the mix, delivering an enveloping musical experience. On the right course, it's a great horse.
