The Shunyata Research OMEGA-X-Ethernet Cable

If you're asking whether a multi-thousand-dollar Ethernet cable like the Omega-X will audibly outperform a properly made CAT8 cable such as LinkUp in a digital audio network, the evidence is very weak.

Here's the engineering perspective:

• Ethernet is packet-based data transmission. The bits either arrive correctly or they don't. TCP/IP networking includes error detection and retransmission mechanisms.
• A CAT6A, CAT7, or CAT8 cable that meets spec is already operating with enormous bandwidth margins for audio streaming. Even high-resolution audio uses only a tiny fraction of Ethernet's capacity.
• Claims about Ethernet cables improving "soundstage," "microdynamics," "time smear," or making digital sound "analog" are difficult to reconcile with how Ethernet actually works. Shunyata's marketing heavily emphasizes subjective listening impressions and proprietary technologies, but provides little publicly available evidence showing audible improvements under controlled blind testing.

We used ethernet cables to transmit special files between robots in a warehouse setting, to coordinate their movements. 

We used ethernet cables to set up server rooms.

We used ethernet cables to connect sensitive test equipment to medical devices in clean room, industrial settings.

Get with the program. We used ordinary cables. And never, never, had a problem. Never had a customer complaint. Our IT team ran the cables through ceiling, and that production facility is still operational today.

The Shunyata is an example of virtue signaling and outright deception.

How many of us who had a dedicated line installed into their system. Only to have their electrician look at them, like why. And this comes from guys who’s been electricians for 30 years. 

now you have a company whose power conditioners are considered world class in some circles. Putting their name on a product that doesn’t equal the quality and value of their other products is not a good idea. So I am going to go out here on a limb and make the statement that flat earthers are not the answer. 

i’m sure that the Mars Rover is using Amazon basic ethernet cables.
