The hifimans are very tempting. For the longest time I've longed to know what the ultra linear bass extension and super speedy mids of a planar magnetic sounded like. Supposedly the HE-400 takes the sound of an HE-500 and gives it the bass of an LCD-2, which sounds amazing.

My local hifi shop has an HD650 for audition, but I'm not sure I'll be able to plug it in to my iPod. Maybe if I use their iDecco, but the problem is that its integrated headphone amp isn't powerful enough for my DT990 600Ω. At best I'd have to theorycraft, ask around or go off aural memory of what my DT990 sounds like on specific songs.
My DT990, for the most part, seems to be all mid-bass. It just doesn't have the sub-bass extension that my Denon does.

There's also the large treble spike, which could have a lot to do with making its sub-bass feel week. If I had a lesser treble spike, I could subconsciously turn the volume up on the HD650 and get a more authoritative sub-bass as a result.
