I purchased my HD 700's today and even though I am currently only hooking them up to my Realtek 1150 audio they sound very good. I love the bass response on these headphones, not nearly as impact as my m-100's (obviously) but they are very very good in there own right. I am noticing the treble spike that everyone speaks about but it is not really bothering me and I've already EQ'd it out with recommendations from these forums.
 
I know that I am probably only getting 50% of what this headphone is capable of as it is not hooked into a very good source and I am already happy with my purchase (New Under $400 USD). Now I need some help on what dac/amp to get without breaking the bank under $300 USD. I want the combo to not any more to that treble spike and possibly warm the headphone up slightly without sacrificing sound stage and obviously no matter what it will be clearer then my on-board. Using this for Gaming, Hip-Hop, EDM, Rock, Pop.

Ended up purchasing a Sound Blaster x7 when it was on a 5 hour sale today for $279. I will report back with my review after I have a week with it. I will have it on Saturday.
