Seconded. If you can spring the extra $80 or so, the HRT Microstreamer will drive them better and give you a DAC worthy of pairing with a nicer amp when you can afford to upgrade; that's what I did, and with my current Microstreamer -> Schiit Asgard setup, I don't feel the need to upgrade any time soon.
Wait, what? HRT Microstreamer can drive an HD-650 better than an E09k? That's a joke right?
