I had the same delima as you. I looked at so many solutions, and read as much as I could find on the net. Late night sessions with burning eyes! LOL
Decided to just bite the bullet and bought the Wyred 4 Sound DAC2 DSDse and the 1 terebit server. It can stream DSD to the DAC over the galvanically isolated I2S USB interface. Should get it next week, after burn in I'll post some thoughts.
