rdwarn,
I would never recommend you crank up a 100w receiver thinking that your "250W" rated speakers will be fine.
They will not.

Forget the speaker ratings. They are virtually useless.
Buy as much power as you can safely afford.

See one of my recent posts (at the very bottom of the review) about the 'test' we did with Axioms and Tannoys on clipping and distortion with a Denon 3802 receiver.
