Technical Network Streamer Question

Do the internal electronics that receive and process the network signal from your computer and/or phone have any effect on the audio quality? 


Or in other words;  If I am using a separate stand alone DAC, does my choice in network streamer not matter?


Obviously each streamer supports different apps such as Sonos, Tidal and Apple Airplay, BUT for arguments sake if they all supported my app of choosing and I was using a separate DAC would they all produce the same end result audio quality, or do the electronics that process the incoming signal from the CAT5 LAN connection and/or wifi antenna play a part in the audio quality as well?
