These are pretty expensive cables, but that's not really why I'm posting. They seem to hold paramount the specification of signal-to-noise ratio, but I have to wonder, since most places only sell 1, 2, and 3 -meter cables, can the signal loss over distance be that great? I wish to soon connect my computer to a Dolby 5.1 receiver via a TOSLINK cable, and I'll need about 10 meters to connect the two devices (I have a Hercules Game Theater XP 7.1, if any of you know about that). That means I'll have to buy two 5-meter cables and a coupler. Does anyone know if this will degrade my signal at all? I really don't know much about the S/PDIF audio specification so if someone could shed some light about signal loss I'd be very appreciative.
