Trying to get my Dad (just turned 70) to get more out of the iMac I talked him into. I've been burning his disks via iTunes, but he's got a sweet stereo system a couple rooms away. I have ATV and stream to that all the time, however his TV is the old fashioned without HDMI.. I want to give him the ability to wirelessly stream music to that stereo system. I'm seeing some old Airport expresses (around 70-80 bucks) that may do the job, but don't know if I need to pull an ethernet cable to it to stream music. I don't want to pull any cable... Any advice? Thanks in advance.
