x3000 and airplay?
I have a new x3000 and trying to use/understand airplay (I know nothing about airplay except from Google the last couple of days). First question, can we use airplay if our music is not from iTunes? My wife's phone is an s5, but her music is not from iTunes, but mostly from Amazon. She has most of her music on her kindle fire, but some on her iPhone. Can we use airplay to play that music? Realize I know very little about airplay, but am trying to learn. If I understand correctly, airplay does not have to be hard wired? One other question, does it play out of only one speaker? The manual says, "select the speaker you want to use".
