Haha, yeah, pretty much!
I've read a lot of different reviews, tests and technical background now and like Luckbad said, it seems that an all-BA-IEM won't really cut it for me, no matter how much money I throw at it. So, I'll probably have to go down the Dynamic route...
Today I got the opportunity to give the IE80 another shot and surprisingly, I managed to achieve a tight (although not really comfortable) seal. Seems like they sound really good with the bass-knob pushed upwards, as far as I can tell after about an hour of listening. The bass hits hard and the soundstage is impressive. Could be a decent choice, after all, even if I probably won't be able to wear them for an extensive period or while sleeping since they stick out of my ears quite a bit.
But the other options you brought up here seem quite attractive too - especially the ASG 2.5, since the combination of that massive Dyn and the two tweeters sound like they could deliver some serious action and hit the sweet spot for me. The XBA-H3 would be available, too, but honestly I can't see myself wearing that... massive thing.
So it'll probably come down to IE80 (sweet sound, not that much comfort) vs. ASG 2.5 (twice as expensive, rather unknown). If they're worth double the money of the IE, the ASG could be the way to go for me, but it's hard to tell since there are really few infos about them around.
