PCM to DSD (DSC1) vs native PCM

Or put other way, DSD goes through much simpler DSP chain in the chip than PCM does

I would have thought this DS DAC would perform / output better sound when fed by DSD vs PCM, your comment of much simpler DSP chain means "better" or "worse" with DSD? I understand it as better but @numlog

there is probably not much better than the 9038Q2M for PCM

So this last comment got me confused

 

@Miska by the way on your Project S2 which filter do you use? fast roll off ?

Yes, better... But not sure about the context here...

 

 

If you send there 705.6/768k PCM, the filter selection has no effect since the built-in filters get bypassed.

 

Summarizing, if using HQPe send DSD to the DAC, not PCM.

 

Are the DAC's FIR filters always bypassed when sending DSD?

I'm sorry it wasn't clear before, just talking about the Project S2 DAC which you mentioned above

Maybe the confusion is about digital oversampling FIR vs analog D/A conversion FIR?

Thank you for clarifying, I was just referring to digital oversampling filters, I do have questions about the D/A stage conversion FIR but that's for another thread / time, don't want to be OT here
