EMM Labs uses a special optical connection between their DACs, players, and streamer that has comparable bandwidth to USB. It might use I2S or some proprietary format. They sound really good. I wish other manufacturers would go this way, you don’t even need to double up the cables, one fiber optic is enough. Unfortunately, there is still a lot of myth pedaling about the perfect sound of ethernet etc. (DCS), which is clearly inferior to optical. What Ted is doing is smart.
