I've connected my iPod through it's iLine out connection on the back of the iDock, to the BeoCentre 2 with BeoLab 5.
I have some tracks that iGot offline, and i wanted to listen to them. So i gave it an iGo. I didn't particularly like the sound, so iFiddled by connecting the iPod to the iMac and selecting all of the tracks in my iPod. Then iWent into 'get info' and turned down the volume limit setting so that it was on below a quarter.
iPlugged it back into the B&O (hid the ugly iThing away) and iTurned up the volume of the system, almost as good as CD. It sounded alot better to me and my partner who came home and commented on how surprised he was when i later mentioned that iWas listening to the iPod.
