Ethernet cables

"Digital is just 1's and 0's" is a good way to think about data trasfer (banks, nuclear weapons, photo downloads) but not streaming.  Streaming can's use FTP with error checking that will take whatever time it takes to get files bit perfect.  Streaming will just move on, play the song, with whatever bits it has been able to gather.  So good cables make a difference.

That said, with the stupid expensive cables you are paying for a lot of marketing, salesmanship, cosmetiic upgrades and perhaps not much engineering improvement. the sweet spot is probably in the middle somewhere.

Ethernet cables like all other interconnects in high end audio can make a significant difference, depending on your system and components they can make an almost imperceptible difference or a very substantial one. Matching the cost with the improvement by experimentation is a prudent method to choose cables. I use DHLabs and Cardas Ethernet cables although I have tried a few others,

Applying logic as to why they should or should not make a difference is best done after you have tried a variety of them, 

As others have chimed in, 

Yes.

As to why, I have no idea, but they do.

Both made in the u.k and much better then main strsam digital cables 

Even a Bluejeans Cat6a will be a vast improvement over any stock Amazon whatever. Of course, the Bluejeans is as far as I’ve gotten! ;)

But yeah, also a decent network switch and linear power supplies wherever you can manage is a big part of it. Finally, some filtering too (not to get too off topic but that also helps):

These are affordable and also made a difference
