Mesa Boogie Strategy 400

I have come across a tube amp that was designed to play a guitar through. A Mesa Boogie Strategy 400 ( used by many big rock bands). I am considering running two pair of Magnepan Tympanis with it. Its 200 watts into 8 ohms. Has anyone used such an amp amd will it sound as good as i expect it should. Some have already said it has a limit to it's frequency range and won't sound as good as i hope. Any ideas or thoughts from anyone on this ? thanks...
