Is the question still relevant?

I have just looked at the manual of the CD-6006 and I think I have found what I was looking for. You should find the relevant information on pages 23 and 46. :) http://manuals.marantz.com/CD6006/EU/DE/index.php

The sound is good, you can hear the horn skin sliding over the strings (harp music). The drawer mechanism should sound of higher quality. Compared to the CD-S700, the electronics eat up more audio formats, including the pristine *.wav. Everything from CD or USB can also be played through the headphones. The headphones are commendably adjustable to the impedance (Sennheiser is sometimes high-impedance). Music from iPod works. Not from Android mobile phones, iPhone should not work either. I'm not an Apple fan ;-)

No, unfortunately it does not work with this system.
