Pro amps for home use?

You can use pro amps with home speakers, but amps designed for home use are often (much) better sounding, usually have more appropriate connections (5 way posts, etc.), and are quieter. I have thousands of watts of pro stuff around (musician, live sound tech) and prefer a 60 watt per side tube amp for my hifi needs.

Sure you can, with excellent results.
I use a Crown XTi on my woofers since I biamp. I have tried it full range on a 3-way monitor with very good results also.
More power on tap does not = blown speakers, however over-driving any speaker could and would result in burnt coils.
The only drawback might be fan noise.

Bryston amps are used in recording studios all over the world. Can't go wrong with these. Excellent warranty. Regards!

I think there has to be a distinction between "pro" amps designed for live sound reinforcement and those used for monitoring...basically hifi in a studio. I currently use and old "bullet proof" Alesis RA100 for my studio as it doesn't need a fan and is insanely reliable...drives live sound monitors really well also (you can drive 2 8ohm monitors per side) so I've used it for small venue shows. I've found huge differences in live sound pro amps also...cheaper Crowns don't sound as good as more expensive QSC or more expensive Crowns. For live shows I've had great luck with a couple of older Mackie M1400i amps that have the quietest fans I've found, although the Mackies may be on the fragile side.
