The difference between CD and SACD/DVD-A/DAD is huge in favor of the latter. Problem is that you need SOTA player to hear it. In your given price range, I'd probably go for a well done CD playback, although the CD/SACD Esoteric SA-10 would be something worth it to look at and save for, especially if you like and own SACDs.
