Well, after my initial enthusiasm I must admit to some new skepticism about the ETHER-C's audio performance. I've been going back-and-forth with the LCD-XC at the office and while my opinion of the ETHER-C's superior clarity and transparency remains, there are two problems I'm seeing: a noticeable hollowness/congestion/lack of impact in the midrange (lack of an "eardrum tickle"), and a narrow soundstage. The latter is also the case with the open ETHER (and something I can live and even adjust with the Isone plugin), but definitely not the former -- the open ETHER tickles your eardrums with the best of them. I'm hoping this is just growing pains during break-in, but given that most of what I listen to is rock and related genres, midrange must be a strength. Hopefully it improves...?
