Ethernet Cables, do they make a difference?

Then clearly you aren't comprehending them.

What planet are you from?

I'm from earth. That may be a different planet than yours.

I guess I’m biased ...

Big time!

I'm not like you who cobbles together whatever hocus-pocus I can find with no expectations ...

Pardon me, but your bias a.k.a. prejudice is showing again. You don't know anything about me, so please don't pretend that you do.

According to your logic, we can only know it won’t work if when the thing explodes.

Of course I never said that, or implied that. You seem to have some problems. Good luck resolving them.

No need to switch to the argument on personalities, just simply get someone to help, do the blind test and... please, please, please, post here honest result.
preferably with details of equipment involved in network connection from the internet to the media player.

Until than - it is a placebo effect which has no scientific background.

Nurse! Thorazine! Man down. He’s mumbling something about blind tests! Nurse!

They make no difference. None. Zilch. Nada. Spend your money elsewhere in your system.

You are streaming 1’s and 0’s. If you hear music, they are getting there. Period.

The 1’s and 0’s are turned into ANALOG by your D/A converter, and THAT matters, but the quality of the cable that delivers the 1’s and 0’s only needs to be sufficient to get them there without loss.

Any cat 5e or 6 cable is sufficient for audio use transmitting a digital signal. Cat 6 is what I use and what I wired my entire house with since it supports 1GBPS speed. I have a 1GB capable QNAP NAS which serves up DLNA/Twonkymedia to my whole house feeding Oppo players/computers/receivers/TV’s etc.

You can test any ethernet cable with a simple cable tester. I terminate my own. I use Southwire brand Cat6 riser cable (home depot) in my walls and I use cheap Monoprice or CableMatters (Amazon) for wall jack to component connections.

Anyone who tells you that ethernet cables make an audible difference in the digital domain does not understand digital data transmission and /or they are trying to profit from your ignorance. The same is true of digital Coax and Toslink (optical); the signal either gets there or it doesn’t.

I’ve been building computers and setting up networks since 1996 and I used to own a Company selling audio cables; I know quite a bit in this area.
