Given that my own preferences are for vinyl and that I

am, nevertheless, interested to know why exactly is it
that SACDs (stereo) sound so much better than the
equivalent CDs?

Same reason that DVD-Audio discs sound better. They
aren't compressed (dynamic range compression I mean) to
within an inch of their life, unlike most modern CD
releases.

Actually, a number of DVD-A and SACD releases are compressed, as compared to
the legacy CD release.

Also, a number of DVD-A and/or SACD releases don't have a lot of content
above 22-24 KHz:

Here's an interesting technical comparison:

The data is incomplete but still interesting. I have a number of questions
about the conclusions.

My analysis is that bottom line, none of the recordings plumbed the
limitations of any of the formats. Most if not all of the evidence can be
explained by the fact that they were mastered a bit differently.

Looking at the summary table shows far less differences between the formats
than one might expect.

Here's another article in a similar vein:
