TuneView provides a great way to control iTunes running on a PC or Mac.   To enjoy iTunes content throughout your house, you'll want to connect your PC or Mac to a stereo system (or whole house audio system).

There are wired and wireless ways to make the connection.   Wired connections can be less expensive and provide higher fidelity -- but can be inconvenient to install (since cables need to be run from the computer to the stereo).   Wireless solutions can cost more and are more prone to interference, but are easy to install since they eliminate the need to run cabling.

Our recommended solutions include:

Wireless Connections:
These solutions receive streaming iTunes content from the PC/Mac via Wi-Fi and  feed the audio to your stereo using standard audio cables.

Apple AirPort Express $99 PC or Mac Link

Linksys Wireless -G Music Bridge $99 PC Link

Wired Connections
These solutions connect to the USB port on your PC and to audio-in jacks on your stereo receiver.  They each feature a digital-to-audio converter ("DAC") that provides enhanced audio fidelity.
