Could you be any more unhelpful to a new Head-fi member? I doubt.
@schsst Archimago's measurements, if I have understood correctly, highlighted a potential flaw that means the DFC might just be driven to clip (and therefore distort) if you listen to very heavily dynamically compressed music at 100% output. If you are concerned about this then setting output to 98% would appear to be sensible for peace of mind.
For the use case that you clearly stated, DAC / Amp for mobile use combined with DAC / Pre-amp at home, then the Dragonflies would be a good choice for an all-in-one solution, in my opinion, based on the many positive reviews of the whole range especially if, like me, you value a small form factor and no battery for mobile use.
In most real-world listening scenarios, most reviews, whether from professional reviewers, who may or may not be critically biased depending on your worldview, or impressions from experienced hobbyists on here, suggest that the DFC represents a step up in performance over the DFR and the DFB. In most reviews that I have read so far (I haven't heard any of the Dragonflies so can't give an opinion, although I am interested in hearing the DFC), where the reviewer has compared across the range, the DFC tends to be preferred. Whether that apparent improvement is worth the additional cost of the DFC over the others is a matter only for you and your wallet.
I would not, and personally will not, be put off by the measurements but understand that for some people measured performance is everything. Try and listen to one in use as a home hifi DAC / Pre-amp and make up your own mind how it sounds. If you are U.S.-based then Todd the Vinyl Junky (TTVJ) is running a loaner programme, with a thread on here that may be of interest.
