After living with them for a while, I must say they're the best small speakers I've ever heard. Great detail, very flat, and in the room, their useable bass clearly goes down to 30-35 Hz. The Beryllium tweeter is a terrific unit.
They're too damn heavy to lug home for a direct comparison with the Pipedreams (hardly fair), but memory tells me they're not that far apart except in deep bass and imaging.
Now, to experiment with amps, etc...
