I'm a new convert to SACD. I tried the Sony DVD 999ES and I own the 775 carousel. I can't recommed either one. In both cases, the CD layer sounds better going through my DAC2 than the SACD layer through the unit's internal DAC. However the Denon 5900 changes all that. SACD sounds wonderful, amazing, better than my Bel Canto DAC2. And picture is superb. What a unit!!!!
