I have had the great pleasure of hearing amps from both manufacturer's and you can't go wrong with either.

I always associate Bryston with SS and the McIntosh with tubes though.

The McIntosh is built to withstand a direct nuclear hit and probably retains a higher resale value.

Older McIntosh amps (1970's especially) are highly desirable to audiophiles. Check out their eBay listings.
