Sorry I was posting from my cellphone when I replied earlier, its an audigy2 zs platinum ex... its featured in this review:

I can attest its a pretty good sound source, this comparing to some previous audio interfaces I've owned in the past. It colors the sound slightly but not in a negative way, not drastically to where the headphones will sound out of character. In fact, my Sony MDR-7506s sound better than ever with this sound card/audio interface.
I believe I may know what is also skewing my perception on the Beyerdynamic DT-770. The fit of the ear cups on the 770s are completely closed ear, where as the Sony's (again I have to make this comparison since I've used them the most for the past 10 yrs and its what I'm used to) , although are supposed to be a closed ear design, actually fit as a sort of a hybrid over ear/ semi closed ear due to the size of ear cup and distance of the driver to the ear. Although the Beyer's do a better job at sound isolation, it closes off air circulation completely and it feels almost as if I have a suction cup on my ears, giving a weird effect like being on an airplane at times when it starts elevating. Anyway, this sort of creates a nasal effect in a way, combined that with the boomy wide bass and it gives it this nasal sound. Most earphones I have tried in the past that claim to be closed ear never really fit entirely closed over the ears, most cups have laid partially on the ear, which always gives a bit of air and perhaps provide some benefit to the sound. This person describes the symptom that the DT-770 suffers from pretty well in this review of the 770s and comparison with teh Shure 840s: http://randycoppinger.com/2012/03/08/shure-v-sony-hphones/
I think what I am looking for may be something along the likes of the MDR-7506, sound wise (character) but with improved, refined sound and improved sound stage. The downsides to the 7506s is the quality of the treble as it can be harsh and mechanical, sort of grainy at times, this leads to fatigue especially if you try to listen for more than an hour with raised volume. It can have a tinny type sound at times and the base could be improved although not that necessary, especially not at the cost of inserting artificial base. Comfort is not that big of a deal for me, at the end of the day, I want a great pair of sounding headphones... as long as they are not as uncomfortable as the Sennheiser HD-25s
