Network Switches

This is why I asked my original question, because I could not see how a switch working at level 2 or 3 can affect the encoded audio (or video, they also claim !) in level 7.

Are you saying that they can or they can’t. It can NOT be both, and bear in mind that you keep repeating that the digital signal is not degraded by a switch

As I just said in my previous post I have never used the word "degraded" in this thread, except to say that I have not used it and that its use can be misleading.

And for the umpteenth time the encoded audio is not affected in the sense of being received inaccurately. The subsequent D/A conversion circuitry and/or analog circuitry is what may be affected by differences in the characteristics of the Ethernet signal.

Every single manufacturer and supplier of these special ‘audiophile’ switches and every single ‘reviewer’ claims that these switches will "improve" the digital audio being passed through them.

In my previous post I suggested that you re-read my (and Atdavid’s) posts in this thread, beginning with the first of my posts dated 10-29-2019. In the very first paragraph of that post I said as follows:

As someone having extensive experience in digital (and analog) design, although not for audio, it is very conceivable to me that a network switch can make a difference sonically. Not because it affects the accuracy with which 1s and 0s are received; not because it affects the timing with which those bits are received; ***and probably not because of most of the reasons that are likely to be offered in the marketing literature of makers of audiophile-oriented switches.*** [Emphasis added].

how a switch working at level 2 or 3 can affect the encoded audio

Just because the sound is better after inserting a new switch does not mean the switch affected the encoded audio.  Couldn't improvements be due solely to a reduction of RF/EM noise in the chain?

All I want is a yes or no.  

and ' for the umpteenth time' almarg
Can a digital switch, as the manufacturers and 'reviewers' say it can, improve audio and video streams passing through it. ?
If you don't know just say so

Just because the sound is better after inserting a new switch does not mean the switch affected the encoded audio. Couldn't improvements be due solely to a reduction of RF/EM noise in the chain? 

So you are saying 'yes, a switch can improve the audio and video being passed through it?  or no it can't.  It really can not be both
Still a simple question.   Again, if you don't know. just say so

@jason_k2017

and ’ for the umpteenth time’....why don’t you pick up a switch and try it on your system? My gosh, even if we say adding a switch made an audible difference, does that guarantees you will hear the same improvements @grannyring and others have heard in their system.

Why this is so difficult for you to understand everyone’s system and hearing capabilities are not the same. You may hear improvements or you may not. At least by trying you will put this to rest.
