no, USB does not do symmetrical signalling.

so probably

TP < coax < symmetric signalling < the "star quad" which until today didn't know exists

The German Wikipedia goes a little bit more in-depth with the graphics:

Yes, I meant balanced line. I couldn't remember the (English) term for this, so I just called it shielding :D

That should *significantly* reduce the noise level, the question that remains is the resistance.

@wolf480pl @aurora

There is a reason the top of the line USB/Thunderbolt cables use miniature coax.

Okay, now I got an even more cursed idea: Ethernet over USB-C, but as in using only passive adapters.

@wolf480pl @aurora

I wouldn't be surprised if this goes far beyond the typical standards because XLR is shielded Coax which, I think, is superior to S/FTP.

The problem is probably the connector, not the cable length itself.
