I'm looking to buy either the denon 2113 or x2000. I'm not sure how the airplay works though. Does the receiver have to be plugged into my network or is it all wifi. Also are either of these dual zone? I'm not sure if I'm misreading the stats but I thought the 2113 was but not the 2000. I'd like to be able to watch tv in one room and listen to music in the backyard. Or at least have a Way to play music in the backyard from the receiver. Any help would be appreciated . Thanks.
