Apple Macbook running iTunes in another room streaming WAV files to Apple Airport Express. iTunes is controlled via iPod Touch at the listening position. I live in Carbondale, IL which also has a great community radio station, WDBX 91.1, which comes in great on the Fisher receiver.
Beautifully simple system. I'm also using a Mac Mini music server and will never go back to CD's. Did you have to purchase a special application to control the Mac Mini using the iPod touch? Thanks!
