@grislybutter - Net is designed to deliver perfect bits. It transmits ridiculous amount of information every second and a packet becomes garbled it is rejected by the receiver and retransmitted.
Can someone imagine military encrypted data to come in a non-perfect way? Legal documents modified? Guess not. Audio stream is basically a file, operation is no different from opening WAV file from a network share like NAS.
No one really develops their own network stacks except major OS manufacturers. It is a complex software that is extremely expensive to develop. So network code comes embedded in the device OS which is typically some flavor of Linux.
What I can imagine is noise added to USB cable that goes from streamer to the DAC. Like by a bad power supply. Or DAC overly sensitive to the USB issues. А DDC reclock/isolation unit may resolve issues then.
But seriously, USB chips are also standard. No one writes custom USB transmission code. USB driver is part of OS or provided by a major driver developer. Ex Denafrips uses USB code from Thesycon.
