HYBRID SACD stereo or multichannel.

"Hybrid" refers to the fact that the disc has two layers, one reflects light at the wavelength of a CD player laser, and the other at the wavelength of a SACD player. Of course, the CD layer, which you can select, is 2-channel. On the SACD layer, there is both a stereo, and a multichannel recording, which the user selects.

DVD-A are multichannel, but can also be played in stereo. In this case the player does the mixdown as the disc is played instead of the recording engineer doing it when the disc is produced. I think this is a better approach because no data space on the disc is wasted by a duplicate recording, and details of the mixdown can be selected by the user so as to give a different sonic perspective: on stage with the performers, or out in the hall.

In this case the player does the mixdown as the disc is played instead of the recording engineer doing it when the disc is produced.

That possibility made up my mind to give DVD-Audio the big miss. Not all DVD-As work like this though - many have a dedicated stereo section. If that had been the standard, as it is with SACDs, I would have been less biased against the DVD-Audio format.

Metralla....I am curious WHY you are put off by the DVD-A method for stereo playback of multichannel discs. It seems to me that the flexible DVD-A protocol is far superior to the locked-in-concrete rules that Sony has laid down for SACD.

Agree Metralla, while I find DVD-Audio's to sound (good enough for me), I'm not going to go the extra mile to enjoy what I can have on sacd with-out extra effort.

Eldartford, I don't have a multichannel system. I have a stereo system and want the hi-rez format I choose to honour my commitment. SACD does this. I want the mastering engineer to mix the stereo track, and I want them to do the best damn job they can, with the same commitment to quality as I have.

The concept of a fold-down offends my purist leanings.
