pure CD player - and DSL-710A inside

I need also the schematic of this (only for information).

This seems like a pure CD player - but a DSL710/DSL710A (DVD mechanism) from DVS inside. How works this before S/P-DIF ?
From there it depends, whether it is really a pure CD player or not (what kind of chipset for PCM decoding, error coccection and servo processing).
Who knows more about this?

By the Primare schematic there are only the DAC, the power supply and the operating processor (user's specific) board.
To get the schematic of the actually decoding, this actually must be right contact:
¡Å¡ñ¡Å¡ñ¡Å¡ñ WELCOM TO DVS KOREA ¡Å¡ñ¡Å¡ñ¡Å¡ñ

The same basic principle than by old CD player stuff e. g. Krell or Creek etc.
Here I still need in all cases the Philips service manual of the regarded mechanism for service ("CDM1-MK-II" or CDM-4 e. g.).
 
here some pictures of primare's d31
