Be careful when choosing a pro amp like a Crown. I had a Crown for a home demo. It sounded ok, but had very loud internal fans. The amp was intended for use in a nightclub or someplace where it would be located in an equipment rack, where the fan wouldn't be heard. If you put it in a listening room, the fans will be too loud. I don't know iof all Crown amps have this problem, but make sure you ask first. But I think Keithr is on an interesting track. I suspect there are some real high performance bargains to be had in the pro audio world.
Which Krell for driving subs?
