No. How could it? But it's likely that the mastering is different on the different disks--and there's no guarantee that the best version (or, rather, the one you would like best) is on one or the other. If both the CD and athe redbook layer of the SACD used the same master, they will likely sound identical.
Redbook layer on SACD - good enough?
New age is coming... just discovered a title that does exist on SACD, but doesn't (on the labels I would like) on CD. I thought to buy SACD with CD layer to play on my Sim Nova CDP, but my concern is whether being on SACD can compromise redbook quality comparing to a "pure" CD.
Your thoughts, please?
