Would I be right in thinking it is the central Identification Index that tells a player that the disc is SACD? I have found that my Sony SACD player reads SACDs in one of three ways

a) SACD or CD according to the player setting
b) always SACD regardless of the player setting
c) always CD regardless of setting

all discs purport to be hybrid. The player is set up to default to SACD, but discs in category c refuse to play as SACD, saying the disc is not hybrid. One might think the player is faulty but it is so consistent in not reading some discs as SACD that I wonder. Has anyone else had similar problems?

Hi,
My SCD-1 work as option A. On winter it need 3 or 4 warmup hours to properly read discs.

Depends on the player. On most you can pre-program your preference on how it should wake-up

Hi, I was not clear in this sentence, I mean say properly sound good, not properly read the TOC.

After the select CD/SACD knob is on CD position the player read the CD layer when the disc is insert.

Sorry, perhaps by saying 'reads' I confused people. I am not talking about the way the disc is read during playing of the music but how the disc is determined to be either an SACD or a CD at startup. All of the discs I am referring to are supposed to be hybrid SACDs on a variety of labels.

My player is normally set up so that if an SACD is played, it should play it as one. But what I find is that a few discs default to CD despite being SACDs.

Whilst that may suggest the player is faulty, it is consistent, in that the player always plays them as CDs, an attempt explicitly to play them as SACDs produces the message 'not hybrid'. The ones that it plays as SACDs it plays them as SACDs consistently, unless I alter the settings to read the CD layer, which it usually allows me to do.

You can tell what it will play them as since when reading the TOC of one it treats as an SACD you can hear it speed up before the indicator light comes on.

Is your system 2 channel or multichannel? If you set a preference for one or the other, it may affect how the choice is made for discs that lack a DSD stereo track or lack a DSD MCH track (rare).

It's set up as M/C as are apparently all of the discs, but I will experiment to see if that makes any difference. The ones it plays as SACD are certainly played in M/C. I do actually have 3 or 4 recordings where I have two copies, and it is always consistent between those.

I am intrigued by the earlier comment about warming up. The player is left on permanently but the ambient temperature is fairly cool.

What do you mean with "sound good"?
My SCD-1 seems to work perfectly anytime.

No, I have tried playing the misbehaving SACDs as 2CH SACD and it makes no difference.
