I may be mistaken, but I don't believe that the new standards for studio audio use TCP. Audio is transferred in hard real-time with absolutely minimal buffering as would be required for sound on sound studio use. (I haven't studied the protocols as the standards are beyhind a paywall.)
One thing is pretty clear, and that is that the Squeezebox protocol is source independent. Once you buffer ahead sufficiently, you can pull the plug and power down the source, playing out of memory on the Squeezebox. At this point there will be little scope for the source to affect the sound quality. (Or maybe not, but if you go there then it is only a small step to worrying about the Ethernet cable at the HDtracks sever to the HDtracks router. Personally, I worry more about the record label shysters marshaling the files that get uploaded to the server.)

the same applies to all the streamers I have in my systems. I can shut down my server software and my computer with my library attached and I can get sometimes two more songs to play.
Yes, isolation of source and DAC. You are starting to get it.
Best way to isolate the source and the "DAC" is to stream the entire playlist at gigabit speeds to the "DAC", power down the source and the network connection and listen to the music out of memory in the "DAC". This was done a decade ago for CDs with the "Memory Player".
This won't work for some applications, such as streaming from the Internet or studio processes such as sound on sound or editing, but this will eliminate the "source" from the equation. If you are impatient then you had best not do any DSP in the computer or if you do so you had best have a very fast multi-core processor, or you can do your preprocessing off-line and store the results on disk if you have stock in Seagate, Western Digital or Hitachi.
