+1 on the bass.
the bass on dba-02 lacks body, and air, but have lots of impact and texture. It also have just enough amount of bass imho. ck10 has lesser overall quantity, but better overall balance in quality. but the quantity always leaves u wanting for more. there will always be "m04r bass pl0x~!" on the ck10, but not much with dba-02.
as for the crash and ride with the decay, i would think the clear space in the soundstage contributes to that a lot more. since it lacks warmth, it has more space trebles.
i also think dba-02 sounds a bit emphasized tho. a lot of details can be heard clearly, but i dont find soft tones coming out as loud to be natural.
U can try blocking the vents in the housing of eterna, that would remove the smears in the trebles, giving better tone, positioning and clarity on the highs, but also cave in the soundstage and removes some mid-bass. when i did it on my ex-v1 (sold it off b4 dba-02 lol), the lack of soundstage and excessive boom of bass really makes me dizzy, too congested. v2 might does better since it's said to be more controlled.
i also noticed that ck10 has a LOT of sibilance compared to dba-02.. but very sweet and smooth sounding, never harsh at all. i like. dba-02 was always hurting whenever it spits 's'.
that's some conclusion that i came going to ck10 from dba-02. so i think that's y i can go ck10 despite being sensitive to harsh trebles.
