If you want to achieve a better sound for your music and movies you will need to consider using an AV receiver. The benefits of using a AV Receiver is that is Connects and switches your audio sources: Every audio source in your home theater should connect to your A/V receiver. The preamplifier section of the receiver allows you to easily switch to (or select) the audio source that you want to listen to.

Connects and switches your video sources: Your video source devices are also connected directly to the A/V receiver, which is connected in turn to your display device. This setup greatly simplifies the selection of video sources when you want to play a DVD, a show recorded on a PVR or anything else. In most cases, you select what you want to watch on the receiver’s remote and don’t have to adjust anything on the display.
