Best sounding IEM for a bass-head: Atrio M5 or Super.Fi 5 EB or?

[DARKHAVEN]

I'm looking for some IEMs for someone who loves listening to rap and techno and loves a hard-hitting, deep, copious bass-line. From the reading I've done, it seems like the Atrio M5 and Super.Fi 5 EB are the big daddies of bass, especially in that price-range. I've read some bad things about the Super.Fi's overall sound quality though, muddy bass, etc. I've heard pretty good things about the Atrios, so I'm looking for opinions. Any other set I should consider?

If M5's are anything like M8 get them ohhh yes they are lovely for bass i love it.. But if you set bass to high your ears will go "Zunnnnn Buzz for sometime like mine now"

Atrio's for sure. Its bass is pretty tight, and incredibly deep (probably the deepest I've ever heard on an IEM).

That's what I'm leaning toward. Can anyone tell me about the fit, isolation, and midrange/treble on these phones?
