I guess the CK100 could be a contender if you like vocal-centric. Other options - UM3X, SM2/SM3, Shure SE530/535. These tend to have more bass than the CK100 and less bright treble.
I would definitely go for the DBA-02 mkII if that's what you're after.
Let me recommend headphones between these 5 (no matter the price)
1. - Sony EX1000
2. - Audio-Technica ATH-CKM99
2. - Vsonic GR07
4. - Hifiman RE272
5. - JVC FX700
I got to have MTPC and IE8. Overall I really like the IE8, but I want to try others with a similar scenario to IE8, many
Thank you very much for these amazing reviews
Those don't sound much alike so it would really depend on what you'd like to see improved over the IE8 and what you're willing to give up. FX700 would probably be the safest choice that doesn't give up the IE8's bass quantity.
