I haven't played around with DSD Direct SACD since I sold all of my collection.
But IIRC, you can't do bass management (5.1) if you use
DSD Direct mode, right?
I remember because I noticed when the
DSD Direct showed on my Denon LCD, the Subwoofer logo on the Denon LCD is turned off. I didn't like that at all. So I don't see the value of using DSD.
