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!
