Schiit Hel 2e (which has optical input and newer ESS DAC) amplifier, DAC, and stereo microphone combination. 1.2 watts at 16 ohm will power almost any headphones on the market. Includes USB 3.0 cable for power, and the 2.0 cable is for audio (less susceptible to interference than 3.0, always use 2.0 for audio inputs).
