I have two Ultra Fi iRoc USB DACs for two separate systems fed by MacMinis wirelessly connected to the web and iTunes music sharing between them.
With a well-made USB cable, such as the Synergistic Research or the Ridge Street Audio, and you'll be very happy. I know I am.
Whether listening to a web-radio station, Pandora, Rhapsody, or lossless ripped CDs from my iTunes library, it's all really great. In fact, I often cannot believe what I am hearing.
Larry Moore (of Ultra Fi) is in the final stages of developing a high-end USB DAC... can't wait to hear it, because the iRoc is quite amazing at its pricepoint.
All the best & happy listening,
Ed
