Hi, I have recently purchased an MSB Premier, a really great DAC..Prior to this I have never used an optical cable in my system and noticed what I believe to be polarity labels, with 'A and B' on each side of cable. I also checked the inputs on the optical side on the Pro usb module, as well as the optical input in the module inside the DAC and there are two different colours, Yellow and Black.
What is the correct way to connect the cable? Thanks!
