<audio geek> When a cd is produced, the analog dynamic range of the original audio source is reduced to the dynamic range that can be represented by the CD format. This process is called 'compression,' and can involve throwing away a phenomenal amount of audio signal. Furthermore, digital masters are made at 48khz per channel, which is down-sampled to produce cds, at 44.1khz which shouldn't ever throw away any human detectable signal (since our ears run out well below 25khz, even for the most well-endowed listeners), but still makes me nervous about digital artifacting (for essentially no good reason, but still).
The CD format, while it is a reference standard of our day, actually leaves much to be desired.
