I have a dock station for my IPOD that lets me hook it into my Av Receiver via several ways- standard RCA cables, S-Video, USB, and FireWire.

Which one gives me the best quality of sound when I hook up to my system.

I have a Denon 4806ci receiver and B&W 804s frotns with an HTM3S center. Pretty good system and want it to soudn awesome when playing my favorite songs through my ipod.

thanks for the help.

The Firewire will give you the best audio quality. But unless your music stored on your iPod is is in a high quality format, ie. WAV, Apple Lossless or perhaps 320K AAC, you probably won't hear much difference between the analog connectoions and Firewire. I'm curious as to what dock you are using since the Denon dock soesn't have Firewire or USB.
