I have auditioned the CK10 briefly before in one of my local audio shops, before having the chance to own the DBA-02 as my main IEM for the past 5 months, which I had just recently sold it off to someone else, not because I did not enjoyed or liked the DBA-02, but because I don't actually spend that many hours outside commuting to and forth between destinations, so I didn't see any reason to keep the DBA-02 when I'm already satisfied with my current CK100s. (I'm currently using the CK100 as my main portable pair of IEM, while relying on my ESW9 cans occasionally as an alternative backup in terms for my portable listening gears)
I can probably elaborate abit on both the CK10 and DBA-02. Both of them do share quite similar sound signature traits, but I won't say if they are similar enough to be considered twins separated at birth though. In my own words, CK10 probably has a more subtle/revealing nature and able to reveal more micro-details than DBA-02, having more of that neutral or balanced frequency response across the spectrum range (in respect, I would say the CK10 is much more similar in genes when compare to phones like CK9/ER-4 if you would like a direct comparison from me) while the DBA-02 is a much more balanced phone that allows you to enjoy your music more, with more quantity of the lower-end response in regards to bass (the quantity amount is still no-where near top-tier dynamic-based IEMs like IE8/FX700 though) but definitely sufficient in my books, that makes it a much more pleasant IEM to enjoy if your music do showcase them such as R&B/rap/hip hop genres, compared to the CK10 which has quite lean bass (but still tight and controlled with decent extension) and to some people, a rather lackluster quantity of the bass impact in order to be able to enjoy these genres.
In terms of midrange qualities, both CK10 and DBA-02 have rather neutral and flat mids, terms of frequency response. They have this aggressive, Grado-ish signature with an upfront/mid-forward presentation, so if you hate this kind of forward-sounding signature, with an energetic crisp-sounding highs with treble spike around the upper-mids then both phones are probably not your kind of IEM. In terms of upper-mids and highs, the CK10 was able to demonstrate a much more airy, clean and articulate in terms of the sound texture compared to DBA-02, but that's only according to my own pair of ears, so your mileage may vary. Both phones have quite an impressive degree of transparency, instrumental separation and precision speed, probably only second next to phones like Etymotic Research's ER-4, which still gets mentioned in some of the many well-known reviews written by the regular contributors on this forum these days.
Does that make either one a better choice over the other? Not really in my books, both IEMs are actually very enjoyable choices according to my own ears, but the reason I went for Fischer Audio DBA-02 instead of the CK10, was because I was already using the CK9, and was surprised at how similar the CK9 and CK10 were in terms of sound signature upon listening, except for the difference in that CK10 has a much better ability in showcasing better imaging, instrumental separation and those refined highs in terms of treble, some of these features which the CK9 was quite lacking of when compared to its newer dual-driver BA successor. Also for the fact the DBA-02 was much cheaper to acquire in my country when I was looking at new phones to upgrade over my CK9 back last year, so the modest street price really helps when I was making my choice over the CK10. (even though I'm a self-professed Audio-technica fan myself)
In terms of build quality/comfort fit, the CK10 definitely gets my vote though over the DBA-02, as I'm not really fond of that braided cable on the DBA-02, and if you search around you would realised that in terms of cable build quality, the CK10/CK100 gets mentioned alot on the forums by many reviewers for being the standard benchmark when it comes to excellent cable build, and currently being an owner of the ATH-CK100, I can't agree more with them.
Cheers.
