It isn't just a matter of sensitivity, but impedance swings; which are less than ideal for tube amps - take something like Wilson or Thiel which might be quite sensitive, but their low impedances in the bass region make for a disappointing match with most tube amps.
If I wanted a tube like SS amp I would go with the Pass XA.5 series, or Ayre.
