Is there any mini-jack converter for the Mac Mini

The Blue Circle Thingee will take a USB input and output coax as well. Of course you can always go digital out (mini toslink) to toslink in on your DAC if you have that facility. I've used both and preferred the Toslink, but that's just me :-)

van den hul makes a great glass toslink that can be had with mini to std toslink config. it's 100$. works great.

Also Tascam in the Pro-Audio world has a USB device that has SPDIF out. They can be picked up at most GC type stores. The last time I looked for one they were about $149.00. I believe the model number is US424.

Wow - A lot of good options - thanks for the replies!

I am using a Wadia 170i for my iPOD with outstanding results (I sold my Reimyo CDP777 and now using a Reimyo DA with the Wadia) but the poor user interface on the Wadia forces me to consider a Mac.

Thanks all!
