Between the router and the streamer then the streamer and the DAC there should be zero change in the signal from one end of each of those cables to the other. The signal within the streamer will be changed of course. That only assumes a basic good quality ethernet cable and subsequently a basic good quality usb cable. Neither is susceptible to degradation from the cable without trying pretty hard to use a very poor cable.So I'm looking to discuss the technical difference between data transmission between the router and the streamer, and the streamer and the dac and whether the former process is as susceptible to being degraded by low quality cables as the latter
