Just a general tutorial for anyone confused:

there are currently two "paradigms" of digital music reproduction:

1. PCM (pulse code modulated)
2. DSD (direct stream digital).

Most consumer and professional media works in PCM. Sony's SACD is one of the few consumer technologies that uses DSD.

The digital audio on CD, DVD, DVD-A, even your iPod and MP3 player is all build on the backbone of PCM.

Any technologies that use compression (lossy or lossless) because of space limitations start with a PCM signal before compression... and end up with a PCM signal *after* decompression. Only a PCM signal can be run through a d/a converter (leaving out Sony's SACD/DSD for the moment).

The difference between lossy and lossless compression is that with lossless you get back the *same* PCM signal after decompression that you started with. In theory, no loss of quality because of this. Lossy compression can't recapture the full quality of the original PCM, and so it's compromised by design.
