A Windows PC with a sound card capable of 176.4 khz coax output and an ASIO driver - in my case an EMU 1212 or an M-Audio 192 (I own both). Benchmark specifically states that on their DAC2, "DoP 1.0 is automatically detected on all digital inputs, and the system seamlessly switches to native DSD conversion." I believe I've read that people have done this with the Mytek as well. I would much rather stream DoP over coax than USB.
