@soix transmission of files over networks is absolutely identical to music streams. There is no concept of jitter in network protocols. Or any loss. Are you mixing up primitive coax AES transmission with internet? Poorly designed non-correcting Red Book or Toslink, sure.
Can you explain exactly how bits are affected between streaming server and your router? What exactly is going on and how information comes down to your rack. What is exactly different in a network packet with FLAC as a file and FLAC as a stream. I am all ears.
