You should probably look at the Gallo Reference 3.0/3.1/3.5 speakers - VERY fast, incredible imaging, excellent integration of drivers, and a reasonably small footprint.
The Gallos love high-current amps, the Berning would seem to be a very good choice. Dave Pogue, a well-respected Audiogon member, is running his Ref. 3s with a very nice 845 SET with modest wattage but huge current thanks to massive transformers. His setup is as sweet as I've ever heard and he is driving his Ref. 3s in a fairly large room, approx. 18x40...
You might want to ping him on his setup and the speakers' capabilities. He is a very nice man and quite knowledgable.
