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!

Thanks david_ten...but perhaps maybe you could explain your point then. I don’t see how shadorne’s statement showed a lack of empathy or sympathy. 
I am hearing that they do not want to try it because, they are so well qualified, they know it will not make a difference. 
@markalarsen and Clearthink:

Damn straight you have to prove it. I'm not delusional about the nature of my hearing and I know it's not a measurement apparatus. I acknowledge the factors that might effect my hearing, including hearing the exact same thing 3 or 4 times, whether I've eaten recently, if I've been around ambient noise all day, if I've exercised, or just being in a mood. Those factors played into my listening just yesterday. I started my day off listening for about an hour. Then I went out to ride some trails and ate sushi after. Sat down to listen later that evening and it just wasn't hitting the spot. I leave the system on all weekend and it was as stable as it was going to get. Analytically, it didn't sound any different, but somehow it wasn't doing something for me. Personal experience tells me these anecdotal stories of difference are ridiculous. It's not like the claims you believers are making can't be verified with some very pedestrian measurements. I'm sure none of you will though.
