Any equipment connected to the last inches of Ethernet cable going to the dCS device can introduce noise into the system. This could be a switch or just an optical - copper converter. That is why I posted a feature request for an SFP input on future units. That way the electronics (power supply for the SFP converter etc.) can be designed as part of the DAC / upsampler and noise can be tightly controlled.
The way things are today with only Ethernet inputs on dCS gear, there is unfortunately no way to avoid noise on the network connection and one is forced to jump through hoops using linear power supplies and the likes to get close to a good solution.
