one product headed for CES that makes any corded 5.1-channel surround system a wireless one, but now you've got one more option. Radiient Technologies is debuting the Roomcaster at CES 2009, a similar setup but based on the ultra-wideband (UWB) protocol. The Roomcaster Early Adapter Kit, which is the rig that will be shown in Vegas, will consist of a single transmitter and six speaker adapters, and we're assured that it can deliver "uncompressed, 24-bit, up-to-eight-channel digital audio at an up-to-96 kHz sampling rate." Radiient has employed a mesh network to ensure dropout-free performance, but you can bet it won't come cheap. In fact, it's downright ludicrous. Wouldn't you call $1,999 ludicrous?
