Imagine someone throwing a floating candy in a stream of water, and then 1 mile downstream you pick the candy out of the stream and eat it. A low grade computer is a contaminated sewer infested stream, with industrial waste, dark brown in color. A high end music server dedicated to audio the stream is pristine, perfectly clean, pure water. You get the candy with either stream, it is the same piece of candy either way, but which one would you eat.
I think you just nullified your own argument? I'm not saying that to get into a fight - but you say it is the same piece of candy either way. Yes it is the same, identical, exactly the same, not different, not dirtier, piece of candy.
In an IP network, the candy is broken down and re-integrated at the receiving end, exactly as it was before. Other than the lag it would cause, it could go around the world, into space through a satellite, and back down and be the same.
What you are saying is that a dirtier computer sends different bits. It does not, or it would not be bit perfect.
It just doesn't and can't work the way you describe. Sewer infested stream, brown water, those are analog concepts if they can be applied at all. What comes out of the network card, over the cable, and to the switch is identical regardless of your pollution analogy. The network doesn't care about the brown water in the server. It just doesn't.
I am not saying that you should not purchase fancy servers. But don't purchase them for sound quality unless you insist on plugging the DAC directly into it without using a streamer, which isn't a best practice according to Roon.
