Reviews of Music Distribution Systems

"Whereas most media receivers send tunes over WiFi or Ethernet, the Logitech avoids the traffic jam and configuration headaches using a widely-known wireless PAN technology - Bluetooth. And over this 2.4Ghz frequency, Advanced Audio Distribution Profile (aka. A2DP) is the only option to transfer stereo audio from the USB transmitter to the receiver."

"There are plenty of streaming media devices on the market, but not too many that cater to an HD set. In fact, Roku Labs may have the only unit that currently supports high-definition output all the way up to 1080i resolution."
