Sony's 5.1ch wireless home theatre audio

Sony has come out with three new "optical wireless" home theatre audio kits, the breath-exhausting "5.1ch DVD/Super Audio CD Digital Wireless Theatre System" range. The system used allows the transfer of uncompressed audio via infra-red, meaning that though you need power cables for the speakers you can eliminate audio cables running all over the place. Brace yourself for the prices, though; the top-range DAV-LF1, pictured, is set to go for an estimated Y300,000 ($2,700), though if you can forego the need for the "lipsync system" to match up the gap between video and audio the cheaper DAV-SR1W is a snap at less than a third of that price.
