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?

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.
DSD layer from SACD Hybrid wins over Redbook CDs. And more important is SACD being played on SACDP sounds lot better than DSD layer to be played on Redbook CDP at the same price range, or even more expensive.

This is a fact.
"And more important is SACD being played on SACDP sounds lot better than DSD layer to be played on Redbook CDP at the same price range, or even more expensive."

How do you play a DSD layer on a Redbook CDP?
Lafish: I've got SACDP some time before, and then discovered that mastering quality on available SACDs isn't as good as on good CDs (IMO), so I decided to get a good CDP instead. When SACD will be mastering with XRCD quality -then it won.
Kr4: is it common to manufacturers to make CD layer worse then SACD layer intentionally?
yeah, but the existence of the transparent layer could pose a problem for the cd player's optical pickup, no? The cd pickup (780 nm) would have to read through the transparent layer designed for the 650 nm SACD pickup, no? might that affect the sound quality of the transport? I don't know for certain, I am just asking. Or is it totally transparent?

I would imagine this would have been discussed to death on AA.
