Delta Sigma DACs


Can a Delta-Sigma DAC translate both DSD and PCM streams to analog?  If so, how does it handle the inherent differences in their coding formats? If not, are there any brands of DAC that accept both formats?

@angelwars  I send the CXU Digital Coaxial Output to the Benchmark Coaxial Input, then use the RCA outputs from the Benchmark to my preamp. 
That's true -- I don't know why, but the CXU only allows me to send DSD via HDMI, and not by Digital Coax.  If I could take the DSD stream from the HDMI output of the CXU, and convert it to coax, I suppose I could feed that into the Benchmark and see how it sounds (not sure if that's possible; does anyone know?).  It's not a big deal, though, because the CXU's DAC does a nice job on my SACD's, so I can just send the analog output from the CXU to my preamp.  
I think Sony are still twitchy about DSD digital output from SACD and where it goes, I don't think there are many AVR's with HDMI that can handle DSD without converting (my Cambridge CXR doesn't) I think we're both fine letting the CXU do the job. If you get the chance try the CXU with multichannel, honestly it's a game changer! :)
