Looking to compare SACD sound with redbook

Tvad,funny you should mention DSOTM.That SACD caused some grumbling.
the multichannel SACD remix has been done with care and taste, and the two-channel SACD version is a straight digital transfer from the analog master tape. But the CD layer...?

JI describes it as sounding "less detailed and more congested...more forward than the SACD layer, and much louder than my original Harvest/EMI (Japan) CD

The Multi/SACD layer is considered revelatory as you say,and glorious.Many things on the masters formerly left off concurrent releases where included in this Multichannel SACD mix
However they chose to aim the redbook layer mix towards listening for mobile or noisy enviroments.Then only did a straight transfer from DSD archive mastering for 2channel SACD,no touch ups or even cleaning the hiss!
It is cooked.
Compressed and limited to the point that many prefer even the more congested of other versions.
