I believe that the dealer installed interface (and the 6FL iPod/USB) uses the line out analog audio available at the dock connector. This is perfectly good quality.
People have found that using the headphone out to the AUX gives poor quality (since it's designed for driving headphones). When they use a special cable that taps the line out in the dock connector to the AUX then it sounds fine.
That said, if you use a USB hard drive with the iPod/USB interface then I believe that the BMW radio reads the hard drive just like it would read an MP3 CD and there would be no analog transfer through the interface. (Note that this option is not available with the dealer installed interface.)
