Here is the best answer so far for the unreleased C9:Will this work with HD800S?
Any headphones that claimed portable friendly should be within our reach and performed well, examples are Meze Empyrean, Focal Stella, Clear, Clear Professional, Audio Technica ATH-AP2000Ti, Denon 7200/9200, AKG K872, Dan Clark Aeon2, ...
We can keep expanding the potential list but it become less important as we dig deeper. To me, the real test are Abyss Diana V2 and HD800. If C9 perform reasonably well with these two headphones, that would clear the doubt of a lot of potential customers. The Diana is pretty compact by design, so make it portable physically but it is relatively power hungry, I personally are looking forward to a portable solution. On the other hand, the HD800 is one of the benchmarks, if not the benchmark. I hope C9 can pass these two tests.
It may be an evolving situation as Cayin tests various headphones and tunes the C9 - IDK if they are set for production or are still in development. This kind of customer interaction helps them get a feel for the current demand and headphones to test - most are likely obvious like the HD800(s) HD820, but some might be outliers that define a subset not tested.I have tried HD800 briefly, with C9 Engineering Sample in 4.4mm power amp mode and N6ii balanced pre out as source. To be honest I have heard better HD800 in many occasions, even within $2000 DAC+Amp Solution (just a convenient amount, I have no intention to indicate the price of C9), but if I were to describe the problem of C9 Engineering Sample and N6ii combo with HD800, "not enough power" is not the number 1 or 2 concern.
So far no indication of the time to release either... I might get an N3Pro to play with and see how it responds, but the C9 is the one that will have the power to support more headphones and 4.4mm "tubey" sound.
