I have Edirol MA-10D monitors and SoundBlaster Audigy 1 with a fire wire connector on the far side. It HAS a digital out and its orange color coded and 3.5mm. I found 6' of coaxial digital audio cable (Koss) at the local radio shack. They had one adapter from coax to 3.5mm but it has only 1 line across. Do I need a 2 line (as in stereo) or is that one all thats required? Can anyone suggest a manufacturer of coax to 3.5mm cable or is that strictly an adapter situation?
