Blanket statement: you'll need ~50W class A or ~150W hi-bias class AB to get the Mezzo singing with appropriate dynamics. (They may be nice speakers but they consume lots of energy.)
So, given current pricing on quality hi-power tubes, I would recommend a SS.
Pass makes nice amps, but to use passive volume control you'll have to match their input impedance which is quite low if I remember correctly (check it out). OTOH, a low input impedance picks up less noise (mine is 10-12k Ohm across the board).
