I'm pretty sure I'm going to get a replacement IC - mostly because I want to be able to play with the DAP while the C9 is far away.
Do you think there's a limit as to length, after which there's a notable decrease in performance?
I'm thinking 18 inches...
Also, the C9 does run pretty hot? More than I remember of the demo, but I wasn't really trying to carry the demo around. Pressing a finger to it becomes very uncomfortable after 3-4 seconds - is this your experience too?
