Article explaining how CD players work


My basic understanding is that there are three elements to how CD players work:

1. The transport "reads" the digital information, extracting it from the CD

2. The DAC translates the digital information into analog form

3. The analog circuitry turns the analog signal into a line-level output

Can someone recommend an article that explains this in more detail? What I am most interested in is understanding the various design issues that account for why one CD player can be so much more expensive than another.
