Network Switches

“There is no way on earth that any of my video or audio can be improved by network equipment or cables........ none”

@mike2019,

Thanks for sharing but with that statement..there isn’t much to discuss further. Case closed 😉

At last

If you challenged me, I would probably go out on a limb and say that no, your technicians probably don’t know the underlying protocols for audio transmission over ethernet very well, but that is a moot point.

As I, Almarg, and others have stated so many times in this thread, which you seem to constantly ignore, is that it is not about digital data transmission, it is about noise injection into end equipment via the data lines and/or power supply lines when USB is being discussed.

However, it is not accurate to say that nothing done in the digital domain for audio can’t effect the analog outcome downstream. Packet rates for audio over ethernet are right in the middle of the audio bandwidth which could lead to power supply pumping in the downstream product due to varying power requirements in step with packet arrival. That pumping of the supply then coupling to the DAC section. At a switch level I could break big packets into small packets to change the packet arrival rate and the signature of that pumping.

Oh my goodness ! get into the 21st century. A network technician should know everything w.r.t. noise free analogue signal reconstruction.

When did I say I was a network technician ? That was many years ago. More recently I have designed and installed networks for the likes of TV and radio studios.
Besides which, if I discovered that one of my tecnicians did not know exactly how sound was encoded into a digital signal, transmitted and then decoded back to an audio signal, he or she will be looking for another job
How can a switch adjust the audio encoded in a digital signal passing through it ???? This is the sort of thing you really must try to learn about. IT CANT

I am not ignoring it, I am just pointing out that it is all about digital data transmission and how ridiculous it is to say that eliminating noise injection can, for example , "enhance the sound stage" and why is this only a problem in an "audiophile's" home network and nowhere else in the world

I am sorry but you just continue to show your complete lack of knowledge regarding digital audio. Mine is very extensive

“I am sorry but you just continue to show your complete lack of knowledge regarding digital audio. Mine is very extensive”.

People with inflated sense of their own importance, a deep need for excessive attention and admiration...isn’t there a word to describe this kind of personality disorder?
