I just received my 990 and I am in the middle of hooking everything up and I have a few questions.
As I understand it using the optical hook-up from my Sony cd changer bypasses the DAC and sends a digital signal to the 990 and the 990's DAC does the processing.
Can/ should I also use the optical out to hook up my Motorola cable box and Oppo DVD player to the 990?
Will they pass the 5.1 surround through the optical?
