Here's a link to a site comparing DVD-Audio to SACD using a square wave.
Look at how the CD foramt using PCM, jsut falls apart trying to
reproduce the wave, but DVD audio, also using PCM reproduces the square
wave quite admirably;

What does this prove, other than that CD has a restricted bandwidth of
22kHz, which we already knew?

Think about it a minute, Stewart. It shows that DSD/SACD have performance
essentially equal to 192/24 pcm. Yet the only place you can find 192/24 pcm
is on the stereo mix of a few DVD-A's. All DVD-A surround and most front
channels are recorded in 96/24 or even 48/24, which the square waves show
as inferior (essentially a matter of bandwidth). So SACD gives you five
channels of near-perfect sound reproduction; DVD-A gives you five channels
of sound reproduction ranging from cd quality to somewhat better than cd
quality (but not as good as SACD or 192/24, the "unobtainium" DVD-A signal.

Which is the superior commercial product?
