Couldn't you also just improve jitter immunity?

I think we have already established that the data is getting read from the disc well enough, so it seems like maintaining much better isolation between the clock and the "dirty" digital section that is presently corrupting it with jitter components would be a more cost effective approach. Of course, that would mean using D/A convertors without built-in digital filters since you want the DAC chips in the clean section, and would necessitate re-syncing the data to the new word and bit clocks generated on the clean side.
Just a thought. I've done it in DACs using BB ISO150 type high speed digital couplers to good effect, only bringing the data across the barrier to the clean side. Much easier in a CDP since you have a fixed crystal and don't have to worry about synchronization.
