Why, if the digital signal is not being degraded and is therefore reaching its destination intact (which is all that matters), do I need a 'special' switch?
@jason
I don't think a special switch is needed unless the hardware is adding noise to the chain via RF/EM interference. One way to address this noise, if being introduced via the switch hardware, "could" be using a different switch that doesn't introduce this noise on the line. I personally do not subscribe to any theory about digital signal getting degraded but I know as a fact that electrical gear can be sources of noise in an audio system. Do you deny this????
I strongly disagree with your assertion that a digital signal reaching its destination intact is all that matters. Introducing new electrical noise along the path also matters! Why are you choosing to ignore this? It's because you're cherry picking your argument. Very few disagree with your assertion on the bits arriving intact! Yes - we get that.
