Why Hippo VB? Why did you consider RE0 initially?
Do you like analytical signature? If so, RE0 is the best choice without blowing your wallet away. But, it has a slight mid-bass hump and lesser bass quantity. It needs an amp to truly shine.
Can you live with the sibilance of Hippo VB? May be you can do a foam mod. It's sub-bass is something special

.
You can also consider M2, which seems to be a very good VFM IEM.
Since you seem to be looking for buying the IEM locally, I cannot suggest any of the two VFM IEMs I have in mind. Anyways, I am not good at keeping my mouth shut

.
So, research on Hippo Pearl (may be available through Moshel) - a balanced IEM with bass, neither analytical like RE0 nor "fun" like VB/DDM.
The other one is Xears TD-100, an IEM which has amazing SQ for the price (which is of course the only thing that manages to fluctuate more than my mood

), but pathetic build quality and tips.
