My officemate has a newly arrived AS06, so I gave them a bit of a demo doing a short comparison with the CCA C10.
Please note one that the AS06 is almost ootb (at most less than 12 hours), while the C10 has atleast 100 hours.
Build and fit:
AS06 is bigger than the C10 so it is more noticeable in the ear. Not sure why but the C10 felt cooler in the ear. Build quality seems similar for both.
Sound differences:
AS06 is definitely darker than the C10, it has stronger midbass presence, which might bleed on some songs. It is also a bit sibilant... Quite noticeable when comparing to the almost sibilant free C10. Soundstage, I have to give it to the C10, again it's noticeably more open imo. The AS06 does sound more fun for certain songs while the C10 is just super clean all throughout so does well in any song I through at it. Mids for both seem quite similar, but the differences between lows and highs are too much that I wasn't able to notice how much of a difference they had.
Conclusions:
I might be biased, but I like the C10 more than the AS06. I've been comparing it with my Kanas Pro and BGVP DMG recently so it's not being shown lots of love, but this comparison made me realize how good it is so I will try using it more often. The AS06 is quite good, even better than the ZSN from before, and it aounds quite polished, and has good bass presence, but the C10 just sounds much cleaner and nicer in my opinion.
Added are some comparison pictures:
