Testing Ethernet switch

One more time, an extra ordinary claim needs extra ordinary proof. 

It's actually quite easy, something I have used with success in the past. 

Try it in your own system (buy used or borrow from dealer). If you like it, and you can afford it, game over. At the end of the day, it has to impress YOU! No amount of external "proof" is ever going to be a substitute for actually hearing the component in your own system.

Well, since you couldn’t resist, here we go again.

Not knowing exactly what something is does not mean it is irrelevant. You continue to dismiss extraneous signal which is being measured (and heard by some of us). This is not an extraordinary claim.  

I get that you believe your knowledge to be superior in this area. Here’s my observation. 

You know enough to be dangerous. You proselytize as if your knowledge is complete, though clearly, it is not. Nobody’s is. 

In the process, you have indirectly or directly accused every single manufacturer of devices aimed at improving digital playback as being a charlatan - selling snake oil. All of them are dishonest?  There are a lot of them. While I’m sure there are some, I do not accept that all of them are dishonest.  Your overconfidence in this regard is quite stunning. Perhaps you should reach out to one of these dishonest companies to ask them what they’re doing and why?

You have also indirectly or directly accused those of us as having decided to purchase such items as being gullible chumps. 

If you worked for me at my company, I’m guessing I would have let you go, even if you were a particularly gifted engineer. You are not aware of your own limitations and seemingly lack intellectual curiosity. People who believe they know everything tend to make poor employees - because they’re poor learners.  And, they tend to be caustic to high performing teams. 

That’s my read on things. You’ll undoubtably disagree with all of it. It matters not as there’s nothing constructive in continuing this thread.

There is a difference between obscure issues and flat out impossible.  An advantage of understanding how Ethernet works is I have a better grasp of impossible than those who are still allowing subconscious beliefs in magic. 

As I said in POST ONE, if you are a believer, this thread is not for you. It is for those who do not understand the technology to be able to make up their own mind. 

Unfortunately, one side factual evidence is still only countered by " I believe so"

If you "believe" and it makes you happy, fine. You don't have to give yours up. Be happy.  If ANY even obscure possibility existed for what is claimed, yes I would try one.  I await said evidence.

Not even close.  He has reviewed a number of network switches and filters and found significant differences.  It's not something "he thinks he heard".  To quote the latest video on the subject, "there should not be a difference between an audiophile switch or network filter being in place, or not.  But there is.  There CLEARLY is."
