I would be interested to know if anybody tries them to know what they think. At 1,500 USD, I doubt if I will be trying them soon. In my experience I have not found any significant improvement in sound in headphones after I reach the 100 - 120 USD pirce range. I once tried a $400 set of AKG earphones and could not hear any significant improvement over my $100 BOSE earphones. But maybe my ears are getting too old to hear the difference.
