I'm buying from the US, but since I do most of my buying online, the prices of the AT's and Ultrasone's are pretty much the same, maybe $20-30 difference.
So basing it off of experience with those of you who own the HFI's, do you think the 580's would be a "downgrade" in anyway to the 780? This is of course, not playing with the EQ, and straight out-of-box. I've heard that the 580 has much more bass, but the 780 has cleaner bass? This is probably attributed to the 50mm vs 40mm drivers of the 580 and 780, respectively.
And, in the case that the 580's do produce better bass, how do they compare to the m50's for overall sound?

Thanks for the in depth comparison, but now I'm a bit more confused as to what type of tonality I want from my headphones. Since my music tastes are quite wide, including hiphop/r&b/rock/ballad/pop, I'd like something that sounds pleasing to listen to for long periods of time in all genres.
Something with good staging will also be nice, since I will also use my headphones for gaming, and positional audio is crucial.
