Ethernet Cables, do they make a difference?


I stream music via TIDAL and the only cable in my system that is not an "Audiophile" cable is the one going from my Gateway to my PC, it is a CAT6 cable. Question is, do "Audiophile" Ethernet cables make any difference/ improvement in sound quality?

Any and all feedback is most appreciated, especially if you noted improvements in your streaming audio SQ with a High-End Ethernet cable.

Thanks!

Great, this is coming from a guy who conduct listening tests on a headphone.

WGUtz didn't have any headphones when I was out there. 

Lying can't help you now. 


My proposal is that gear that is susceptible to a change in a short length of Ethernet cable is faulty.
My proposal is that gear that is NOT susceptible to a change in a short length of Ethernet cable, need to replace POS gear!

That's your understanding of scientific method, huh? Invent a theory. Invent a test that validates the theory. Theory proven. Uh.... No, that is not how this works. Clearly he developed something quite flawed. 
That is the scientific method. How many DACs have you designed, manufactured and sold? Bel Canto Design is a top brand, and the Black System is one of the best ever. Check Stereophile.  
The Oxford Dictionaries Online defines the scientific method as "a method or procedure that has characterized natural sciencesince the 17th century, consisting in systematic observation, measurement, and experiment, and the formulation, testing, and modification of hypotheses".[1]
