CES 2011

Denon and Marantz are the first non-Apple manufacturers to incorporate AirPlay audio streaming without the use of an AirPort Express device. An AirPlay logo appears on your iPad, iPhone, or iPod touch (running iOS 4.2 and up). Press it and a drop-down list of compatible devices appears. Thus you can take music from an Apple mobile device, or a PC or Mac running iTunes, and stream it hither and yon to your Denon/Marantz toys. The capability is built into four Denon a/v receivers -- the AVR-4311CI, -3311CI, -991, and -A100 100th anniversary model -- plus the N7 tabletop system. Also on board are Marantz products: the SR7005 receiver, AV7005 pre-pro, NA7004 network audio player, and M-CR603 network CD receiver. You can get the software upgrade for $50 two days from the publication of this item. (Photo: Lisa Cazzola.)
