The MusicCAST2 supports various file formats including iTunes AAC, MP3, WMA, FLAC and WAV, and can play back tunes from iPods, Bluetooth devices and other Yamaha accessories with its built-in dock port.

If you prefer, you can even plug in USB flash drives and the MusicCAST2 can also pull audio from sources such as Rhapsody, Internet radio, PC and Macs and NAS devices.

Is your room configured to handle 1080p video footage streaming over a network? Then you’ll like the Aztech WL850MS Wireless Multimedia Streamer. It’s got some specs that make it different: 802.11n Wi-Fi technology, Multiple-input and multiple-output (MIMO) antennas for extra coverage, 2.4/5GHz dual-band capability.

It will be less prone to interference from cordless phones, bluetooth and the like with the dual-band capability. It will cost you about $263 for the WL850MS transmitter/receiver kit.
