If you can stretch your budget to 7K, the Ayon CD-3 may be a good choice. I listened to the Ayon CD-1 which is a model below and impressed.
I have also listened to the Marantz SA7S1. While I don't have a chance to direct A/B comparison, my impression is that the redbook CD performance of the Ayon CD-1 is at least at par with the Marantz, if not better. The 6 moons review is spot on with this player.
