1. They are used when the player does not include decoders for the digital audio tracks that are on the disc, but the user does not want to use LPCM for whatever reason.
2. They are used when the user believes that the DAC circuits in the player are better than the DAC circuits in the processor. This is valid when the processor uses analog circuitry for its multichannel analog inputs. If the processor redigitizes its multichannel analog inputs, then usually there's not much point.
3. They are used to find out if there really are any differences to be heard in the sound produced by the two different DAC circuits.
There are several different methods used to clock, upsample and derive quality sound from PCM audio, especially from CDs. The processor and the player might not use the same techniques. Some people seem to be able to hear differences between them.
