Acora acoustics granite speakers

Has anyone heard them? I got a strong recommendation from a friend who works in an audioshop. He is extremely knowledgable and has heard all the best / top gear (and sells it). He regards acora as pretty much the best hes ever heard. I am really interested. 

Heard them last year at the THE show in Long Beach. Overall,very impressive. Really smooth and extended with a natural and organic sound. Keep in mind they are very heavy (obviously!) and pricey, but the sound was top notch in my opinion.
