I know you didn't hear any Diva speaker that's why you couldn't speak objectively. I heard their 6.1 at New York Audio show last sprint. With room full most expensive speakers, like Wilson, JML Utopia, Lynn, running on exotic amp. Only with a outlaw 1050 receiver, 6.1 sound very good compare to them.
Look www.avsforum.com and you will find hundreds posts from Diva owner.
