I think you mean RBCD and DSD??
If so, you have Dacs like Lampi that have separate engines for DSD and PCM. In fact my Dac has 2 dsd engines and one PCM engine.
The Lampizator Atlantic has DSD256 and R2R ladder PCM for about $4,500 retail (single ended version). Not a single Dac chip Inside it.
SaCD needs to be ripped to the DSD64 file using an older PS3 ripper or any of 4 relatively cheap Blu-Ray players with the mediatech chip. Details over at Computeraudiophile forum.
