I got my DT990 (600ohm) in the mail today! I'm using the headphone amp on my HT Omega card set to 600ohm to drive them (replacing this card with Xonar ST very soon) and I can't tell if it's driving them well enough.
If an album isn't really loud, @ 100% volume in windows it isn't loud enough for me. It seems like in itunes I can turn up the EQ a bit to amp it further...this oddly doesn't seem to introduce distortion if I don't go too far and makes it much more acceptable (I'd love to know if anyone else has tried this)
As for the headphone itself, it will take me time to settle in with it. It's really interesting and I like what it does with bass and treble, but it seems like it's being held back by volume some how. I owned Denon D2000's for two years (a year back) and obviously these aren't going to be like them, but i'm totally not used to open headphones, i'm hoping someone can help me out here as i'm not sure if I can tweak these cans to sound like I want them to, or if it's just the nature of open headphones.
