Best IEMs bass-wise for S9?

[LSD25]

What are the best IEMs for S9, basswise?
price range doesn't really matter.

I bought Q-Jays today and tried them on S9, and I was pretty dissapointed, I'll probably return them tomorrow.
No doubt the sound quality is really good, but it lacked that bass to it, I like 'resonating' bass that stays for a while. Q-Jays' bass is sort of "short", and gets distorted at high volume.
how do SE530s sound on S9?
