@sns is correct with the issues he has raised. There is great white paper by the guy who built the EtherRegen and the OpticalRendu that gives a road map to great streaming sound using his products. This approach does not care about what is used to serve the music. A massively powerful computer or a dedicated audiophile server. Though nothing is connected directly to the DAC via USB or Ethernet. There is an intermediary that serves as a moat between source of the music and the DAC.
If interested I can find a link to the paper or forum post.
