My understanding of airplay is limited, but I think it goes like this. airplay audio system plays audio from your computer itunes, ipad or iphone through the wifi to an audio system. What I am wondering, if this is the case, does anyone have a decent home audio system that works with this setup? I would like to install in-the-wall speakers with a head-end somewhere, so that I can be on my ipad or iphone and play music throughout my home. It would be nice to also have zone control so I could play music to just the den, or office, etc while the other speakers in the house are off.
