100+ Head-Fier
I have to admit that the DFR has some glare in the treble regions which does detract from treble detail, but then again the dynamic presentation of the DFR more than makes up for it (I use mine mostly with the DT1770 Pro)
Personally I think that a lot of people miss the point of the Dragonflys. Its a USB stick that's powered purely by it's host, and in the red form can drive some reasonably demanding headphones. It really is what I would consider to be the ultimate portable DAC/amp at the moment, due it's form factor. However to deliver a product in that form factor is going to require some compromises along the way.
This isn't a be all and end all DAC/amp, and it's certainly no Mojo, but what it is, is a highly portable and effective device for listening to music on the go. It's not something you would buy as an only DAC/amp solution, but more something you would buy as an "on the go" alternative compliment your main system, or if you choose to run high impedence headphones as a portable solution.
I'm actually thinking about picking up 2 or 3 more of these so that I can have one in my bag at all times and the other two connected permanently to headphones that I use for portable duties - that way the DFR and the CCK cable simply become part of the headphone cable. I'm that impressed with it, despite the slight failings in the treble that I've found.
Actually, I think it would be good enough to be an all-around dac for many folks that aren't constantly comparing gear. I have an Opus #11 that some claim sounds indistinguishable to the Mojo for IEMs (driving power isn't the same) up for sale because my preference still leans toward the Red for my iPhone (also, because I don't want to charge 2 devices or have it ever run out of juice).
