Ethernet streaming and occasional white noise on Windows

[Mohmm]

Yes Mac plus iTunes plus AIR wifi or AIR ethernet reliably gives continuous white noise after as little as 15 minutes and as much as 4 hours.

Sorry, but that may be true in your setup, but it's not true as a general problem.

but: lack of symptoms is not evidence that there isn't a problem.

Sure, as a scientific principle one can never prove the absence of a phenomenon. But still I prefer to have no symptoms and to enjoy the music.

As an aside, many threads here and most audiophile discussions throughout the internet testify to people's searching symptoms of inexistent problems. The principle is: "If there is no problem tweak your set-up so long as to produce symptoms."

[Epistemologically this would be the reverse of Ockham's Razor principle, if you know what I mean ;-)) ]
