I could easily recommend the HD600 with either an Asgard 2 (more like a better O2), or maybe Valhalla 2 if you want more of an ethereal sound and more speaker like. DACs can vary, but i would stay away from Sabre DACs and Burr Brown. AKM DACs are probably your best bet. A lot of good professional audio interfaces use AKM chips such as Steinberg, Lynx, RME, etc.
I also like the Schiit Mulitbit DACs. Bimby is a good buy if you can stretch it as it's upgradeable, and there is supposed to be something coming out this year I believe.
