got a pair of these a few days ago, on casual listening, they are definitely tuned different from the W3000ANV (my fav) and far better than the esw9. But I found them to be excellent and love them, and like anything limited that I like, I promptly purchased another pair.
I got them for about 500 US at a store in Hong Kong call "Let's go" at the Wanchai Computer shopping arcade 2nd floor, where there's an excellent selection of headphone stores that sells a very good selection of products. I found an A-T Hard case for my ath-esw11ltd at another store there. If you happen to be in Hong Kong, should drop by for a look.
I find them to be excellent too. Though many here say that the ES10 and ESW11LTD sound similar or the same in some areas, IMO that is not the case. They sound quite different.
