Can SACD's be played in ony 2 channel format


I have a Denon 2910 that Im using now as a CD player (sort term only). I only have 2 SACD's so this is not that big of deal,but if I understand the technology correctly the SACD's are recorded at a higher resolution than regualr CD's. After reading the instruction manual I'm still not perfectly clear on wether or not if I play a SACD it will output the 2channel info as the same as the equivalent CD source.

Most are two channel. Many are multi-channel.

Most are multi-channel but have stereo tracks. Many are stereo only. ;-)

Kal
Are the stereo 24 bit or 16, or does that vary too?
Stereo tracks are either 16 bit (CD layer) or DSD (SACD layer).

I believe no more than 1 in 5, of the ones I own, are MCH. None of mine are classical.

I think I got it. Is the SACD layer for multi channnel or can you have SACD 2 channel? Sorry for so many questions, but I just want to be clear.
To answer your main question,yes.I'm not familiar with your Denon,but on my Marantz,when playing 5.1 discs, I have to switch from multi channel to 2 channel because my system is stereo only.The player has rca outs for front,center,rear,and sub.I just use the front outs to connect to my system.A click of the button and it's in stereo mode.

That is why I inserted the smiley. More than 9/10 of mine are multichannel and 9/10 are classical.

Almost all multichannel SACDs will have both a stereo and a multichannel track on the SACD/DSD layer. There are 2channel only SACDs, as well, but these lack a multichannel track, of course.

Kal
But is the 2 channel 16 bit or 24 bit playback?

Also, I read this ariticle from 2002. It doens't seem to kind to SACD's, but alot of it was over my head.

I would have thought SACD's would sound better than traditional 16 bit record players/recordngs, but according to the this particualr fellow it doesn't seem so. Except below 10k.

What are your thoughts.
The 2 channel SACD tracks are DSD- Direct Stream Digital. It is a one bit datastream at something like 3 MHz sampling rate. It is completely different from PCM which can be 16 bit or 24 bit, but I believe the theoretical resolution is something like 20 bit (which is all you need anyway since current technology does not have the signal to noise ratio to support a 24 bit signal).

your player should be able to turn multichannel 5.1 into a usable 2 channel output. Nearly all DVd players can output a two channel form of any 5.1 sooundtrack. So the SACd is no different. If the SACD has 2 channel. you get two channel from the stereo outputs. If the SACD has 5.1, you will STILL get a two channel mix from the stereo outputs.
I own a Denon 3910, and a Denon 5910.
Receivers are pretty sophisticated. If it is NOt doing this for you, go in the menu and you can change it to do so.
As far as I know all SACD's have a stereo layer. Pressing the "Super Audio CD Setup" button will cycle between the CD layer, the stereo SACD tracks, and the multichannel SACD tracks. You can also go into setup and select the default layer for SACDs.

The above posters are generally correct. There are exceptions, though.

they just don't understand what's really important when it comes to audio resolution but at least their hearing is 100% OK.

see the below quote from the article:

"The SACD recordings from Jan-Erik Persson at Opus3 are far superior to everything released from DVD-A."
IMHO, such blanket statements of absoluteness are rarely correct.

Opus3 SACDs are fine. Just wish the music was more to my taste.

You need to pay more attention to the last sentence. The frequency range below 10K corresponds to 9 of the 10 octaves of human hearing (and the vast majority of musical energy). So even if you accept what he says as true it is possible to draw very different conclusions.

I have a Denon 2910. Put it in pure direct mode for all your 2 channel listening - it'll play SACDs into 2 channels. You'll see a 2 speaker icon on the unit when you hit display. In the Super Audio CD Setup, select "Stereo" (as opposed to Multi or CD). I too only have a few but the SACD sound is wonderful. (hope I'm understanding your question correctly).
