hey I was just wondering if the length of the USB cable matters for audio interfaces, or at what point (length) performance becomes effected?

I'm just messing around with a Scarlett solo during his interim, and have a chance to mess with various orientations and configurations for a few (prof of concept) swipe I've started to get going.

What is the difference between these 2 cables, and can I use a standard XLR interconnect -- out from an inrerface AES EBU -- to digital AES EBU in on a DAT recorder?

thanks.
