Perhaps when you get the time - would be interested on how it compares to the the AP100 on its own.

Fantastic Review as usually! If they release a version which is more suitable for iems, and fix up the design inconsistencies, they will be pretty killer!

@Light - Man and @RedJohn456: Thanks for the comments. Will do an A/B of C5DAC and AP100 when I get through some of my review backlog. One thought around the AP100 is that is has variable line-out functionality, meaning it could be a good pairing with the C5DAC if you want to use sensitive IEMs and get more low power volume control.
