Squeezebox is a great little product that can be used wireless or with Ethernet cable and is only $300. Resolution is pretty good, but not quite CD quality. The new Duet, also by Logitech, is similar, but with the display on the remote, $100 more. The Slim Devices Transporter is reputed to be much better, though I haven't heard it, at $1995, I believe. You might try the Squeezebox through a DAC, assuming you have one.
