I drive Focal Maestro Utopia towers off a set of X260.8 Pass Labs monos. There is plenty of power and the sound is holographic, prestine and has plenty of authority.
I would think the Int250 would have all the power you need. Worst case, Pass amps hold there value very well, especially if you buy used.
