Yes, I use them both together often. Excellent combination, the full sound and pristine detail of the DAC2 coupled with the warmth of the HD600 provides superb sound. The DAC2 has more than enough power to drive the HD600 effortlessly.
BTW, for the HD600 if you want the best sound try replacing the stock cable with an upgraded one.
