Very cool. I'm absolutely loving the detail and resolution of my ad900x's through my ele dac (no matter what I'm listening to... trance, dubstep, rock, whatever). When I throw my E11 into the mix though, it still sounds great, but I think that I am losing a bit of that detail/resolution. From everything I've read, the C&C's would probably be a clear upgrade from the E11. I suspect that the E12 would as well. So, I'm definitely looking forward to your impressions of both! Thanks.
