"The reality is that DVD has MUCH less information that a CD. "
That depends. There are DVDs with lots more info/data than a CD.Kal
Follow Ups:
I should have been more specific.DVDs have much less AUDIO information, because of the rest of the space taken up with video. That is why DTS (on movies) is perferred because it has more audio data, but still a lot less than a CD.
DVDs can accomodate more audio although they rarely do. The Classic Records HDADs and the older Chesky DADs were video DVDs with high-resolution audio. Similarly, you can get DualDiscs with more audio(resolution and/or channels) than possible on CD. Finally, take a look at what AIX does on the audio side of their discs.Just because the bulk of DVDs has less audio is not an indication of the lack of its capabilities but of the lack of interest on the part of the manufacturer.

Is a DVD able to handle more data than a CD, yes clearly it does & we both agree on that.HOWEVER, on a movie DVD the standard set by both Dolby Digital & DTS are for less information (data) than is on a CD.
Can a company put a cd or higher level of data on a DVD, yes they can.
Do they? Generally the answer is NO.
I agree that some music dvds are recoreded with high levels of information. You give good examples. Once again if you look you can find DVD music that is recorded at 24/96 which any DVD player can play. But finding these discs can be a challenge.
The point I was trying to make with the original post is that the audio quality of MOVIE dvds is nothing special. Sometimes, movies have a seperate 2 channel tracks, which is (sometimes) recorded at CD level of data. Which may be the reason the stereo feed sounds better or it may be that the player has better dacs than the receiver.
neither you nor the OP mentioned MOVIES until now. (Yes, it appeared in a parenthetical reference in your second post.)I have heard excellent movie sound that exceeded what you get on CD but, as you say, "finding these discs can be a challenge."
Since my interests are primarily in music, in any delivery format, I don't usually face that problem.

Yes, you are right, I did not mention movies in the original reply. I was THINKING movies, though ;-( Sorry.I would be interested in your experiences with any differences between dvd-A & SACD.
Understood. I was thinking music.Differences? I could have been happy with either.
In terms of effective sound quality, there's little to choose between them. In terms of convenience, I find SACD easier because it uses regular CD-like controls without OSD.
The big difference, imho, is in repertoire because, as a classical fan, SACD has it all over DVD-A. There are exceptions but SACD outnumbers DVD-A by about 20:1.
