Yes and No

The Sony uses a sigma delta stream that uses a DSD-type signal during the conversion process anyway.

The only option it does is to convert the signal to DSD and feeding it to the sigma delta DAC or let it remain in PCM before sending to said DAC.

The only DAC that I know of that has two DAC chips inside is the AMR DP777 which has a traditional R2R chip for 16/44 PCM and a sigma delta chip for hires (tho the DAC does not support DSD signals today, the sigma delta chip it uses can in theory support that).

I recently built a quiet PC and for kicks decided to run JRiver on it.

I enabled DSD2x up sampling of all media (a mix of CD lossless quality, HD material as well as DSD 1x) and was pretty amazed at how much better they sound than sending it natively to my own DAC (which also purports to convert all incoming signals to DSD2x)
