I usually like reading Mike's reviews and find his listening agrees with mine so often. This one wasn't badly written, but it was too short. He might do a longer review later.
It's good that these haven't got the stepped attenuators and that could be a reason why they released them. The Soloist SL, which I like, doesn't have them potentially annoying clicks when you change volumes. And if you use a wide variety of headphones for a variety of sound streams (not just from foobar 2000 - youtube, movies, online TV as well) you'll find yourself changing volume often. My ears are sensitive to the clicking of the original conductor anyhow (long demo).
For me the price is an issue. I don't want to pay £1k for it. £500 - £700 would be much better.
