One of the big advantages of using it for an audiomaster is the ability to control bass, treble, loudness, and balance from your listening chair using the remote control. A big advantage over the "purist" approach of no tone controls at all.
I almost never use the CD player in mine, but I have a set of the B&O demo CDs with the pretty art on each one that they used as demo discs in B&O stores. A weird and wide variety of music, and they look gorgeous in the player. Even if you never use the CD player you should get some really attractive discs to load into it. Might as well make it a real artwork.
