With few exceptions in this thread, and we can discount them, has anyone suggested that the signal or data degrades.
This has thrown me
Yes, many of you have. It is the whole point of this thread and my original question

Several people have states that a 'special' switch will prevent it from doing so. Or are you now saying that a special switch is totally unnecessary as the signal or data does not degrade ? Please make up your mind

No, only a one or two people who do not understand digital data transmission have suggested degradation of the digital signal. That vast majority of the posts have spoke to electrical noise being the most likely culprit.

I have also posited, because it is real and it happens, that data frame arrival, because it is periodic (and pseudo random) can also cause pumping of the power supply lines in the end equipment as the power supply load increases and decreases. That will be in the frequency range of audio and whether audible will be implementation dependent.

So if electrical noise does not degrade the digital signal, why do I need this special switch?

I don't understand why people think it's technically impossible for a switch to introduce noise in the component chain.  Switches are powered by electricity and contain fans, chips, printed circuit boards and power supplies.  This isn't an argument about bits are bit and 0's and 1's or buffering or any of the well understood ethernet data transfer protocols - its about noise.  Why is this so difficult?

This isn't about degrading a digital signal, it's about electrical noise riding on the line.  What do you think shields ethernet cable?  It's wrapped in foil or braided wires - yes, conductors of electricity.

 So if electrical noise does not degrade the digital signal, why do I need this special switch?
