I just purchased this DAC. So far I'm just using it hooked up to my hefty Cayin Cd player, and man it sounds awesome right out of the box. The bass is pretty amazing. I wanted to eventually use it hooked up to my macbook, but have absolutely no experience with the computer as an audio medium, except for itunes and ipods. I understand the mac has a toslink but I don't even know where it is on my computer or what it looks like. What would be a good mini-toslink converter, and what would be a good toslink cable?
