So if there is no consensus in this forum that the data will be sent correctly over the network to the network end device and that this is the basis for discussion here in this forum, then you are right.
I'm not talking about the fact that a switch cannot increase the sound quality, but that it does not change the data less than 20 $ switches.

Since you are not electrically minded, think of the noise that is on top of the USB signal as a virus. Currently the tools we have to measure that virus is a 18th century telescope. We know it’s there, can hear the effects, make a good guess of what it is, but cannot measure.

Thats why there is very little data since it is difficult to measure in the first place. When I mean difficult the instruments are well beyond most professionals starting at EUR150k +++ and that won’t get anywhere close.

What’s so difficult about measuring noise in an analog signal? It’s really not rocket science. I’ve not heard of such expensive equipment being required for the task. What exactly does this super-instrument measure?

Ok, any high impedance probe on a scope has far too low an impedance to measure this conducted noise. It is necessary to have several gigs of impedance, so the scope will have no influence. 18th century telescope is what we have now.

It easier to measure noise at frequencies above 30 MHz, since the receiver is decoupled from the source. Soon as there are conducted emissions through a wire, the story radically changes.

Then it should be trivial to show  an example that demonstrates the need for such high impedance probes. Something that demonstrates that with standard probes or the cheaper analyzer probes there’s some significant noise that’s being missed. Can you please share this? 

Oh! You’ve never held a scope to a signal and the problem went away or was worse? This is lead loading, never experienced this ever.... ? then I take it your expertise is software and theorist electrical,  that’s ok.
 if you have a closet full of USB cables and can’t hear a difference with any of them, then your perception is different to the most of us here.

So nothing objective to share to substantiate your claim then, other than to call into question my hearing abilities and to attack my expertise (of which you know nothing)? You misunderstand the nature of objective evidence. It's not, and cannot be, based on any individual abilities or uncontrolled perceptions.

 

Conversation is now a parallel. No further dialog necessary, bye.
