Although our tunings may differ, I more or less share the same experience with my MX400, where it's only shortcoming is a lack of quantity of mid and subbass. Otherwise, the detail and imaging are top tier, better than anything I've ever heard. I just shipped my MX400's back to Wong for repairs, so I'm hoping that goes well!
It took me by surprise initially, but I quite quickly adjusted. Detail and imaging are really very good, the driver clearly has its strengths. How do you find vocals on it? On mine they're impressively human in texture and nuance.
