This is my first post here so hope this is all correct and is worthy....
Logitech's Squeezebox is a fantastic network music player that transmits all the digital music stored on your PC to your stereo - through Wi-Fi or cables! Easy to set up and use, this powerful, well-thought device produces high-quality audio, without any skipping or delay. Its large, elegant display shows track titles, artists and menus: you can browse by genre, artist or playlist, or randomly mix your music. The Squeezebox also gives you access to a practically limitless number of Internet radios, even when your PC is switched off. "
This is an amazing bit of kit, the sound is fantastic as it has burr brown DAC's.
They are around £199 online and seem to go for a fair bit on ebay.
I picked one up last night from PC World for £59, the product code on my receipt is 0000424887 if there is none in stock in your local store they might be able to locate one for you.
