Thanks so much for the detailed reply, Fred. Based upon your response, I will continue using the coax output from the Touch, as it does send 24/192 to the W4S DAC with the installed EDO. That is a much appreciated capability. Kudos to Triode. I think the Touch is the best price/performance value in audio today. I've been using it as a stand alone device connected to my stereo. I wanted to avoid another hardware purchase by using my current PC and external hard drive in another room as a music server, ethernet connected to the Touch as an interface with the stereo. I've looked at the W4S dedicated server, which can be operated wirelessly with the Logitech Squeezebox Controller app and provide an I²S connection to the W4S DAC2. I think this and the other features of the W4S server would obviate the need for the Touch, but that's another $tory . . .
