Only at the S'phile Show in NYC, so I can't tell you much that is reliable.
They do work despite appearances (!), they eat power, they're hugely expensive and according to the review of one model at stereophile.com the fancy metal mesh hat messes things up.
Now, they're not junk. You would have to like the omni idea as a concept, which to me means having a relatively large and well treated room. They also are not shy below about 120 hz, so you'd have to like that.
I would never buy them if I were looking for just one pair of speakers in that price range unless on the basis of looks. But they can be fairly magical at times in spite of everything I've said.
I'll be curious to hear others' impressions.
