Make sure you decide on the IEM that you will like, as you found re252 to be bass lacking, DBA are less likely to suit you (but as santosh said they are technically superior, thus have better reviews ), you are bound to find better reviews of DBA-02, stating its the best, if not better on par with CK10.
But with DDM you will be happy as it has a lot of bass quality bass thats never overpowering, but in reviews you will read that the FX700, SM3 and IE8 does this and that better.
If you had asked for a toptier IEM without your history with RE252 , allmost all would have suggested re252. cause as faheem said re252suits your description perfectly.
if you can try both and decide, nothing better , but if you ask me for which IEM suits you better , it would be DDM , rather than the DBA-02. As i have alwys said go for SM3 if you want best of both worlds but thats very expensive.
