Atrio M5 MG7 vs. TFTA

Has anyone had the privilege of comparing these two yet? I am looking for an upgrade from my SE215 and essentially I want better clarity and moar bass  I'm looking for something that isn't warm or dark. My nicest phones are the Phiaton MS400, and while I love and enjoy them, they just seem dull in comparison to the SE215, despite having better overall SQ; the darkness and warmth just makes everything feel sluggish, I am definitely looking for a more aggressive sound with deep, hard bass impact. I listen to a lot of hard-hitting electronic music, so I want something with as deep and rumbly bass as possible (you know, the kind you can feel) without drifting into the mids or drowning out the highs; when I EQ, I generally sock the 250 hz spectrum to about -8 because I hate the sound of a mid-bass bloat. I refuse to sacrifice clarity for big-sounding bass.

Also if anyone has heard the SE215s and can compare to either the MG7 or TFTA I would love to hear whatever they have to say 

Other suggestions are welcome as well, whether they be IEMs or no.

That's good to hear, they were at the top of my list until I started reading about the TFTAs. I think I will probably wind up going with the Atrios, as they have the blessing of good testing and are generally well-regarded, but the TFTAs just sound so intriguing what with claims of bass bigger than IE8 and Atrio. My only concern is wondering if they make unacceptable sacrifices in mids and highs; as much as I want to believe they don't, for over $150 on headphones I'm not taking that risk, especially with claims of them needing so much time to burn in, always makes me suspicious...
