This is a "Hi-Fi Topic" video: In this video I show my journey of discovery with USB Cables as used with Audio equipment. The video isn't meant to be a complete guide to USB Audio, but rather just what I have been doing with my set up and what I've discovered. I'm just getting the information out there.
