Mac mini to eq using toslink?

if the dac accepts toslink, then it will work fine. if the dac uses coax, i would recommend going out of the mini to a jitter device, then use coax into the dac. going straight into a dac from a mac or any other music server without a dac sounds terrible..

go out and purchase a jitter device (monarch, audio alchemy, genesis, etc..) and go from your mac into this jitter device using a toslink cable. then go from the jitter device into an external dac using a digital coax cable. this will give you optimal sound. don't try to make cables or convert 1 type of cable to another. also, skip the usb connection until somebody comes out with a dac that actually will work with a usb cable. the new audio research dac just might be the ticket for the folks loooking for a usb dac.

you need to get an adapter at your closest fry's for $2 and place it onto your toslink cable and plug it into your mac. the adapter is a little longer and allows the mac to send digital signals. all of my mac and airport express devices uses this setup. i have never heard of your dac. what you can do is try the connection from your mac to the dac using a toslink cable and see for yourself if there is a difference. only you can tell. if you don;t hear a difference then you are in good shape.
