There are about a million ways to stream music from your PC to other locations in the house, and now Sony has added yet another solution to this lengthy list: the 2.1 channel CPF-IX001 wireless streaming music system. The compact device uses your existing 802.11b/g setup to pull tunes from iTunes, Windows Media Player, Sony Connect, or other applications, and creates a unique IP address so multiple units can operate simultaneously over the same network. To cut down on wire clutter, Sony employed a so-called power line transmission technology that allows the main component to send both juice and audio signals to its subwoofer over a single cable — pretty handy, especially if you’ll be moving the system from room to room.. Expect to see these in stores sometime next month — although we don’t actually know what to look for, because Sony is being a little stingy with the product pics — for about $300.
