Also, the explanation I stated has nothing to do with "mangled bits." For example, differences in risetimes and falltimes do not constitute "mangling," or lack thereof. They are just differences, that may or may not have different effects on downstream circuitry.
As I said in the first paragraph of my post:
... it is very conceivable to me that a network switch can make a difference sonically. Not because it affects the accuracy with which 1s and 0s are received; not because it affects the timing with which those bits are received; and probably not because of most of the reasons that are likely to be offered in the marketing literature of makers of audiophile-oriented switches.
