Depends on what you want to see upgraded over those two really...
ClieOS: I have the brainwavz B2 and I've read they are very similar in sound to the DBA-02. I find the B2's congested and somewhat flat sounding in terms of their soundstage and how they use it, at least in comparison to the GR07. Is this how you hear it also? or do you think I'm having fit issues with the B2's?
The sound otherwise is good, bass is fine, treble is clear etc It just seems like the notes lack body that extends out across the soundstage.
If it sounds thin that is a fit issue IME. If you aren't willing to have a deep insertion like an Ety using the B2 it will always be thin.
