Isn't upsampling (DAC) not so different from...

...converting MP3 to FLAC? How can one pull more samples from a given amount of samples and presumably 'increase the sound quality'? Links from old threads that I searched are mostly dead.

Not at all, the aim of upsampling is not to add more information, but to make the implementation of filters easier.

"The effects of upsampling are greatly debated. While it is true that upsampling does help us in attenuating the amount of jitter caused by sampling errors and an inaccurate clock, whether this jitter is audible or not is a point of contention. There is no doubt that wide bit words and super-high sampling rates that are touted by the latest products are largely marketing. Oversampling has been around for a very long time and has been used extensively in audio products to not only improve sound quality through 'better' filtering but to make these same products much cheaper. Upsampling, on the other hand, is relatively newer and debated greatly. The effects of upsampling are no doubt overstated."
