This excellent presentation on dynamic range, limiting, mastering by Alan Silverman was discussed here before and largely dismissed.
I started to laugh when that video got to
26:45. This is exactly
what I was talking about, above.
I have to say that I'm a bit embarrassed for the guy doing most of the talking. I couldn't really imagine the cognitive dissonance of "first, do no harm" contrasted with "this is what makes a good mastering guy". That's a pretty deafening situation (pun intended). I know those guys (mastering guys) couldn't do anything about it during the height of the Loudness War practices about 15-20 years ago. The problems all reside at the record companies (and the folks that have fastened onto the "loudness war aesthetic"), none of which I can associate with the idea of "hi-fi".
I waited, and I'm still waiting for that to happen, but unfortunately, 10 years later, I have not seen any such effect. Not even a trend pointing in that direction when looking at the DR database or when analyzing tracks on my own.
This is that "organizational culture" that I was referring to. (If you want to read about organizational culture, I really recommend
this source. This is something that basically everyone needs to know and understand.)
The circumstances being that the market rewards loudness by level maxing at the expense of dynamics.
It used to, I think. No longer is this such a straightforward association (looking at the YT video posted above that is discussing this). I think this kind of thinking is actually "walking around dead", in terms of what's obviously occurring with streaming music. The video was a good example of this.

As far as SACD and the DSD format in general...I'm a format investor (about 200 discs thus far, i.e., insuring that multichannel DSD is going to the DACs , and not first being converted to PCM via PC-based electronics). My view of what I'm hearing that's different will probably upset a few readers here...
My view is that, since the mastering guys can't use their typical EQ and other analog filtering techniques (DSD doesn't allow this), what you are actually hearing that's different is that the phase fidelity of the produced music tracks is much more intact than with any music that uses typical PCM-based mastering processes that the mastering guys use.
If you've got a setup at home that preserves phase fidelity to the listener's ears (i.e., including control of nearfield early reflections via loudspeaker design/placement and in-room acoustic treatments),
you can easily hear this difference, while those who have large phase growth in their loudspeakers' crossover networks or in the physical driver offsets within the loudspeaker can't really hear that difference.
YMMV.
