For a closed can, TH-600's, the new Sony Z7's, Mr. Speakers Alpha Dogs, and ZMF Vibro's would all be good options. The TH-600 is slightly V-shaped (a little extra bass and treble for and engaging sound), the Z7 is getting good reviews, the Alpha Dogs are probably closest to the sound signature you want, and Vibro's kinda fit in with the same general sound & value. I've only heard the TH-600's, fyi.
If you can go open, that really opens up options. You could maybe even swing some used LCD-2's, T1's, new AKG K712's, HE-500's or HE-400i's or HE-560's and put the rest in an DAC/amp.
I'd recommend putting as much money into your headphones as possible, and for your DAC/amp, just get a DAC with a clean sound that has all the inputs you need, and an amp with enough power. I'd recommend the O2/ODAC combo as being great for any of the options listed (it's hard to beat until you spend a lot of money), though something with a little more power couldn't hurt. The Schiit Modi/Magni could do that for ya.
