Ethernet cables

What I find amazing is that what Bob Stuart and Gordon Rankin say on the topic counts for nought in @bluemoodriver’s world. Stubbornly doctrinaire against better science, init?
Unfortunately a common trait among ‘scientists’ it seems...
Here s another one for you @bluemoodriver: why do you think the filter I was referencing was originally designed? To improve the accuracy of scientific medical instruments! Go figure! But that was obviously done in error because the lab had a fundamental flaw.....

These guys who say Ethernet cables do not make a difference:

1) Typically say nothing makes a difference. Of course other than room treatments and to a certain extent speakers, which of course everyone agrees

2) They have sorry a** systems, if any at all

Here you go, I said it. Harsh but true.

Having said this, using a good Ethernet cable will NOT make your $50 China DAC sound like a $10,000 DAC. Let’s be realistic about the impact of Ethernet cables

For those still on fence for Ethernet cables, give this a shot:

I almost never recommend anything China, but I do recommend Ghent. Great build quality at very affordable prices. Fast shipping from China too

There aren’t many places left where “led by science, engineering and objective evidence” is a term of derision!

Now you have said that “guitars sound faster” I’m convinced. You are right. That’s all that’s needed - now the cable you selected and installed with an expectation that the sound will improve has reported by you to improve the sound by making the guitars sound faster, it proves that science, engineering and objective evidence is stupid. 
Silly me. 
With some notable exceptions like Doug S and Audio2design, too much of this forum is a dead end of the worst sort of audiophilia. The sort that causes our hobby to be derided and the people in it mocked. 
So carry on with suggesting science, engineering and objective evidence is a reason to be dismissive and rude.  Ignore your confirmation biases, your aged ears, the placebo, blind testing, and measurement. 
And then complain that young people don’t join you in your hobby.  You wonder why?
