SACD is multichannel 16-bit/44.1kHz... so multichannel CD without additional sample resolution (if I recall). SACD is not "backwards compatible" though, whereas HDCD is. DVD-Audio is really the way to go, though... 24-bit/96kHz multichannel or up to 192kHz two-channel. Lots more bits, lots more samples. It makes a huge difference on "pretty good or better" gear.
