Network Switches

Is not the sole purpose of the equipment in question, in both the professional and amateur setups, to get the radio/TV show from a to b ?
What @david 22 in UK?? Are you asking whether the sole purpose of an audio system is get sound coming out of it? An Alexa speaker does that job very well.... so...
@thyname...

This is the level of blatant ignorance and misinformation that I have come to expect from some of the people on this thread...

"It is all about some form of noise (usually either voltage noise or phase noise) hitching a ride along with the digital data (the bits) and getting into the DAC. This causes distortions in the analog signal which somehow affects the human perceptual system. THAT is what an "audiophile switch" attempting to accomplish: getting rid of those noise components before they reach your DAC."

...and this is the level of arrogance that is driving me away...

"I am pretty sure you are one of those people from audio "science" forums claiming that all DACs sound the same, and a $50 DAC from China would provide the same SQ as any SOTA DAC. Heck... someone told me there that a DAC is not even part of the audio signal / chain !!"


My point is that regardless if whether the digital signal is perfect, it is susceptible to RF/EM noise riding along or being created by power supplies and any gear (including switches) that pass electric current.
Sorry but I still don't follow how the digital signal can be susceptible to your "RF/EM noise" , and were it to be possible why is that not considered to be a problem by the professionals. You do realise that in the UK we have DAB radio ?. It is digital all the way from the microphone to the receiver.

No, I am saying that in this case the sole purpose is to safely deliver the audio data. The only difference between an Alexa speaker and the most expensive hi-fi system is the quality of the DAC, the amplifier and the speaker(s). The data it receives is identical. You are thinking of analogue audio.

Back to my original question.

Is there anybody who can explain why the professionals need only normal cables and switches?.

What are they doing differently and why can't I do that on my system?

Ok David you have to stop this.  Again I am NOT saying that the digital signal is susceptible to noise.  I have gone to great lengths to say quite the contrary.  This is NOT about the signal so please stop.  What I am saying is that noise can get introduced to your system equipment (not the friggin signal!) via electrical gear including routers and switches etc just like power supplies in any other piece of gear can create RF/EM noise that get transmitted through the air or hitches along the foil/shielding on an ethernet cable (or any other cable) causing an affect on other equipment - and consequently sound quality.  Please, this must make some sense to you.

OK three_easy_payments   now you have to stop this

You said in your previous stab at an answer;

Oh dear, you seem very confused on the subject.
And once more, please, please read my posts more carefully.I did not question the correctness of what you said. I am simply asking why this is not deemed to be a problem by professionals.

Please, this must make some sense to you.
So I will try again.

And I would appreciate replies from people who are not confused and who do not keep contradicting themselves.
Hey, you know what? I am going to telephone the BBC's technical support department for a definitive answer. It is what I should have done in the first place, I will let you know their answer
