Listened to these cans at T.H.E. Show at Newport Beach last weekend. They had two models (didn't know the model numbers) on demo with one retails for about $2100 and the other for "a few hundred bucks less," according to the representative. I like the $2100 model a lot; they sound well balanced with good midrange and decent bass (sorta like LCD3s). The demo was off from a mini iPad and rechargeable/portable amp, so couldn't judge whether these would scale-up or not.
Talked to the booth representative and he said that the crossover point can be configured by changing a cap inside (I suggest perhaps a mini-pot to set one's own).
The construction is industrial but looked better in real life than through the pictures. The idea of dual-driver is interesting...But $2100 puts it in a very competitive range that hard to convince a buyer for a try.
