Ok, I have no problem admitting that some of the dac signal processing you lay out here is over my head!
But to answer your question, on the BDA-3 DAC, the difference in sound when the upsampling is engaged is pretty stark. It is almost like the signal is being passed through a lush tube buffer. Better? Definitely different.
I also wonder how hardware upsampling like the Bryston scheme differs from upsampling at the server stage, like with Roon, or even HQplayer. Upsampling to DSD was in HQPlayer was a big fad recently.
Now with Roon providing that capability along with the previously discussed powerful DSP tools they provided with the last update, to me it looks like MQA is more obsolete with every week that goes by.
EDIT: I am also reminded of the SONY HAP players, which have a user engagable "Remastering" process. Digital filtering of course.
