I recently added a stand alone DAC to my Esoteric DV60 Universal player. Before, I could play back SACD’s...through the DV-60. Now I cannot play these discs as SACD's. BUT, and here’s the thing, the improvement that the DAC made to the whole SQ is far superior than what the sound of SACD’s was through just the player alone. Surprisingly, even true with the CD layer of SACD played through the combo. ( and the DV-60 is no slouch on playback!) OTOH, the combo can play back DVD-A’s as this digital stream is passed through to the DAC. I looked at Paul’s very interesting video, and of course it made perfect sense. BUT, I do wonder if DVD-A’s could be ok from a copyright and artist royalty scenario, why SACD’s could not? Seems odd.
Also, I think that the idea of SACD is good, except I also think it was hyped too much. IME, the quality of the sound one is going to get is far more dependent on the quality of the original master recording, and a lot less on the the fact that is is a CD at 44.1 vs a SACD at DSD.
