Got the SACD today. It sounds great. DR is stellar as expected. And if it was anything but stellar this type of music would be ruined in my opinion. At moderately loud volume this SACD sounds fantastic. To me, low and marginal DR music sounds worse the higher the volume.
As mentioned I'm no jazz expert and I do not have golden ears but I'm pleased. The separation of the instruments is excellent. Coltrane's sax during several solos is pretty far to the right but I suspect that's what it would sound like if he was in the room. Davis' horn is dead center. Bass is pretty well centered and fills the room. Drums just right of center. Piano to the left. Adderley's sax is center-left.
In All Blues during Davis' quiet solo you can barely hear Cobb swishing the brushes on the snare and later just barely tapping the ride. Very cool.
Can't really compare this to anything else other than Qobuz, which I don't intend to do. No need for my purposes. I'm happy.
