Well mastered Compact Disks

I think most of the MFSL SACDs I have bought are really pretty good.

A few monthes ago I bought (I think it is Analogue Productions) Cowboy Junkies/Trinity Sessions SACD and it just about blows me away.

I have a Japanese digital pressing of Holly Cole/It Happened One Night that has a sense of presence and immediacy that does it pretty good.

I also have 4 digital pressings (two of them are SACDs) of Patricia Barber/Cafe Blue, and the three I have listened to (including the red book) sound fantastic.

MFSL’s old red-books of Elton John/Goodbye Yellow Brick Road and Moody Blues/On The Thresh Hold Of A Dream sound pretty good to me on my stuff.

And I am not picking these because they are Musty Old Oldies But Goodies/Blasts From My Misguided Past that used to live on my turntable; I have plenty of digital reissues of other albums that meet that criteria that hurt my ears. Nails on chalkboards.

On those MFSL SACDs I alluded to: I note that your OP was referring to red-book, but that’s what my CD player was when I first tried them. The red-book layer sounded so good I bought a SA10 to see what I might be missing that was on SACD.

I think the MFSL red-book of Eric Clapton/Slowhand and sounds quite good.  Another one I did NOT choose simply because it is a reissue of a  Moldy But Goody Blast From The Past--I chose it because the guitar work seems to float in the air and Clapton's vocals show the strain of the excesses he was indulging in during that period.  

Recently I played the live red-book Patty Larking/Agogo which was the first time I've listened to it since I upgraded my CD player and preamp.  I am not a musician, so I don't know the vocabulary to describe the sound of a guitarist hitting the strings, but it sounded right-up-front/in-my-face and I felt like I could almost feel air exuding out.  Which I realize is unrealistic, but it's the way I felt when I listened.
