Hi Mike, the Marantz is a very good player, I had a CD6005 which sounded good anyway but when I teamed it with a decent DAC it really came alive. I believe the CD6006 uses the same transport mechanism so I would be tempted to try one out. I'm afraid I've no experience of the Cyrus so I can't say if it is any better than the Marantz.
