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

no, USB does not do symmetrical signalling.
so probably
TP < coax < symmetric signalling < the "star quad" which until today didn't know exists
@[email protected] @[email protected] @[email protected] Good microphone cables are “star quad” (https://en.wikipedia.org/wiki/Star_quad_cable). I don't think I've ever seen coax XLR.
@simon_m @wolf480pl @aurora @rojun @MrDOS ooooh!
Also, one star quad would easily suffice for 100 Mbit/s.
twisted pair or "normal" coax, with one in the middle and one around. Maybe shielded, but I don't think so.
