I have also!! They've replaced some aging MIT. Opened up the soundstage,improved timbres and clarity. At first they sounded a bit bright, however they have mellowed with use. The midbass in my rig is tuneful again!
The IC's are terrific. They have made my inexpensive Cambridge CDP sing!
Both are jacketed in a Pearly White Mesh which makes them kinda sexy looking. My wife has never really liked the MIT's with their drab grey!!
Highly recommended!!
