Rabco - it is a mini-Toslink (1/8" jack, same diameter as a mini audio output/input). I prefer, and use myself, something like the Van Den Hul Optocoupler optical cable which can be ordered with one end pre-terminated with a high quality mini-Toslink connector; rather than using an adaptor.
Toslink vs SPDIF converter..optical wins
I was a little skeptical regarding the use of an optical TOSlink 'tween my cpu (Mac Mini) and my DAC (MSB Full Nelson). My experience with TOSlinks prior to my forays into computer audio were negative. I never cared for their sound.
I was using a SPDIF converter and a coaxial connection to my DAC, when I first upgraded to the Mini. Once I obtained the cable with the adaptor necessary for the Mini, I took the plunge, scrapped the SPDIF converter, and went direct to the DAC with the TOSlink from the Mini.
Big difference. WAY cleaner. Opened up the soundstage. To my ears (I have a tube preamp, and tube amp), now the best system I've owned in terms of sound.
Tip of the hat to others on the forum that pointed me in the right direction.
I love it when the plan comes together.
