I have not heard the ATC dome, but I did own Dynaudio Confidence 5 for years which employed their best 2" midrange dome.
Midrange was incredible, very life like and detail. micro dynamic was superb. what I didn't like was image lack density and focus. could be the speaker box design, could be the flat face of dome midrange. I would image ATC horn like surround would improve both efficiency and image focus, but that's pure speculation.
I have heard lesser midrange domes, they just don't sound as convincing as Dynaudio Esotar midrange dome.
