yoyoyaya, about that rounded bottom design, I wondered if they come with a plumb-bob to verify they are set up vertically. ;^)
Seriously, it looks very awkward to me. I agree that round surfaces belong at the top if utilized.
And no, I've not heard them. Nor would I put much credibility on hearing them at a show -- only generalized impressions. I've attended audio shows over more than 20 years and seldom heard a demo that I felt comfortably represented the in-home sonics of a system.
But I'm not in the market for $28K speakers, so none of my opinion matters.
