Is anyone able to tell em whether you can connect an airport express via an optical cable to a BC2 socket box. I have an ordinary analogue Aux. A. connection between the two and that works fine. I am wondering whether I can change this to optical digital to improve the sound. Am I also able to use the S-video on the BC2 Socket box to do the same thing - play music fro my computer to the B&O system. Do I just purchase an optical digital cable from an electronics shop?

Many thanks 

the optical is an outbound connection if i am not mistaken. for airport express you need inbound.
