SACD = Super Audio Compact Disc
Instead of using PCM (Pulse Code Modulation) as CDs (and DVDs) use, where the audio signal is sampled 44,100 times per second and each sample given a value in a 16 bit word length, the SACD uses DSD which samples the signal 2 million,822,400 times a second (2.82 MHz, 64x CD) in 1-bit. This is supposed to give a sound that's closer to analog smoothness than anything else can achieve (DSD was designed as an archiving format to preserve recordings for the future) and according to many audiophiles, they agree. (Just ask GoldenRedux
). Even better than 192 kHz/24 bit PCM.[quote] Did somebody call me?

A SACD can have up to 6 discrete channels (not 5.1, six full frequency) (Some Telarc SACDs have used the 6th channel as a height channel for example, other SACDs use it as the regular ES/EX back surround, and of course many as the normal .1), depending on how the title was recorded, you may get original Mono, original Stereo, 3-channel Stereo, (many early Stereo recordings were made as 3 front channels and mixed down to 2 for LPs), Quadraphonic, 4.0, 5.0, 5.1, or 6. If the title has a Multichannel mix, it also has the original Stereo mix in the disc.
A SACD recording has to be played on a SACD player.
Many SACDs also have a compatible CD layer so you can play them on regular CD and DVD players (The CD layer is Stereo (or Mono) only of course). It's all on a single side. No Combo flipping . These SACDs with CD layer are called Hybrids.
More than 4000 titles have been released, some gone out of print.

Deci has summed it all up quite nicely.
