I share the OP's excitement about the technology. It seems to have so much potential for excellence by virtue of eliminating so much of the traditional signal chain.
Putting my money where my mouth is, I bought a C390DD to play with. I'm not ready to offer any final judgement, but I will say that it's very good sounding and it's probably not as good sounding as my traditional separates, which are much costlier. But its flexibility is mighty appealing. I still need to play with the analog input module, (RIAA applied digitally), and the subwoofer functions, as well as the room EQ, which I believe is still a pending feature. USB input is sub-par but is modular and likely to be upgraded in the future.
