I have the 7700 and have listened to the 9000. Neither is a "good" CD player, although the 9000 is far and away better than the 7700. Where the 9000 shines is playing SACDs.
If you goal is good CD playback but you also want DVD, I would get a cheap DVD player, such as the Sony 360, and look at some of the standalone CD players in the $1500 to $2000 range.
