Not to draw this out but that was my point. It only supports those higher rate over I2S input. Doesn't that require that you have yet another device between the computer and the dac to generate that I2S signal? I am not aware that most computers have an I2S port? Sorry if I am a bit confused about this. My current Sabre dac takes a direct input from usb and plays native dsd 256 and 512. No I2S conversion necessary. Or am I missing something here?
