heard them last year at RMAF. they were the only (and i mean the ONLY) one of the "super-speakers" that actually floored me. most of the uber-expensive speakers didn't really sound all that much better than my salks (and some didn't sound as good as them). i was not alone, BTW - the group of people that were in the room with me were similarly impressed. however, i must add, that what was REALLY impressive about the demo was how little drop of SQ there was when they changed from the big utopia grandes to the new smallest of floorstanding utopias, the viva utopias (which are still mega friggin expensive).
edit: as for the OP's original question (do they justify the price) - of course not, how could they. i am answering that question as a middle class average joe, however. if you play in the stratosphere and are going to spend insane amounts of money for things like stereo speakers, than yes i would say they are the class leaders (IMO again).
