You know what's really awesome about their Live Demo system? It's NOT being done electronically with EQ... that special IEM actually has ALL of the drivers necessary to mimic every CIEM they make (UEPRM excepted). The iPad engages and disengages drivers as needed in order to simulate each model. I've already asked UE if I could get that super CIEM, offering my left nut or firstborn as suitable payment, but its not going to happen. Oh well, I can but dream.
I wish someone at the UE booth had explained that to me when I used the system. I would have been a lot more likely to trust what I heard. I just assumed the the phones attached to the iPad were TOTL and they used equalization to approximate the sound sigs.
