Nice list, and prolly fairly exhaustive to boot, but if one were to lay in such a DAC/amp mostly just to support the CMA800R dual mono configuration, which one(s) would you perceive as the biggest bang for the buck, or at least without introducing significant deterioration of SQ, such as signal distortion or diminished staging, which would kind of defeat the purpose of the dual monoblocks? Your Yulong DA8, such as yzap referred to? And you'd probably need to multi-task such a component in your audio set-up, anyway, just to justify the additional purchase.
It would almost seem preferable to try to balance the channels just using the two CMA800R onboard volume knobs, so that you don't introduce additional sound influence or weak link with another amp upstream, especially since the preponderance of them use voltage controlled signal gain.
EDIT: To answer my own question, the Yulong DA8 and Nuforce DAC-80 seem to be the only ones on your list that are cost effective as a front-end DAC/volume control component addition for the dual CMA800R monoblock configuration. I would just hope that they would at least hold service for allowing the dual CMA800R sonic attributes to be well displayed.
Altho as an end game set-up, cost is no object, eh? ;)
