Update on good Ethernet switch

@tonywinga  you have a few details correct, but you are missing a lot, like 90%.

 You are correct in that Ethernet sends a sine wave, however, depending on the speed, it could be as high as 4 simultaneously waves. Ethernet uses something called a frame to transmit over the wire. Built into the the frame is a crc check, so if there is anything that goes wrong, the frame is discarded. 
also important is that Ethernet standards, regardless of speed over what’s called an Ethernet cable (twisted pair) has building common more noise rejection, that handles most noise, certainly all noise in a residential setting, at speeds less than 2.5Gbit/s. 
 

what you are also missing is that it is a stack of protocols, called TCP/IP, which ensures bit perfect transmission, 100% of the time under normal operating conditions. And you are missing that most music services that provides per song streaming actually downloads a large part, if not the entire song (Qobuz does the entire song) as fast as possible, it doesn’t take very long to download a 24/96 FLAC, seconds, and this download is done over HTTPS, which is encrypted, so you can miss any packets at all or the decryption will fail.

so, now that you have more information, it is easy to see a switch cannot do anything to improve. A poorly design switch can detract and introduce packet loss, but no switch can improve. It is not how the protocol stack functions, in fact it is the opposite of how it works.

Just go away Fred. You are not my saviour.

Bleating on the same drivel. Reminds me of George.

Huh? Word salad.

Word salad. What are you trying to say?

As you know, I've previously shown an experiment that disproves that claim, so please stop repeating it.

Sir Isaac Newton made some observations about falling objects and developed a few basic equations to describe the motion of bodies.  It took some time for people to accept his equations.  Then Einstein came along and showed that Newton’s equations were not entirely accurate.  Still, the observations never changed.

Many of us have experienced and observed that audiophile grade ethernet switches improve the sound of streaming music.  I have even observed it dramatically improve the picture quality on my TV while streaming.  Therefore, it is an exercise in futility to insist that an ethernet switch can do nothing.  Try to be more like Einstein. 

@fredrik222 Your explanation is spot on.

On the internet data reaches the end user via hundreds of such ethernet switches.

TCP/IP protocol ensures bit perfect transmission at every stage.

If it was not true than I will see random missing letters in the data I read on my screen!!
