Transparent DSD DAC/chip

[DVDdoug]

I'm not an expert but since there is no fixed-calibration between the DSD level and the output voltage it should be possible to for the DAC to adjust the volume as part of the digital-analog-conversion. Or, simply adjusting the level of the analog output should work just as well. (Either of those could be digitally controlled.)

that's why it's sometimes advisable to convert it to Hi-freq PCM if some changes

Done properly, many programs actually maintain the original sample rate, for DSP to be applied.

So 1-bit 11MhHz (DSD256) becomes 64-bit 11MHz, DSP applied, then modulated back down to 1-bit 11MHz for D to A

Roon , JRiver, HQPlayer all treat DSD DSP this way.

Even ESS and AKM when not in DSDD mode, although probably 32-bit and final output is 5-bit 11MHz, not 1-bit

So what is the benefit of doing that in software compared to a conversion to a lower rate PCM? Preserving ultrasound noise from DSD modulator? It wouldn't even do that, since the extra re-modulation will generate all new noise.

I wasn't hinting that this was better than PCM out

Only a comment about how DSD volume is handled for DSD output
