"Is it better to up-sample in the software, before the Dac, or at the Dac, or not at all, and why?"Depends if it's synchronous or asynchronous........ Asynchronous conversion is not as true to the original digitized signal as synchronous conversion, and I personally don't like how it sounds. Synchronous conversion is often known as 4x or 8x or 16x oversampling...... Used to be common back in the 1990s..........
Most upsampling is done at the DAC..... If done before the DAC, there is more high-sample-rate signal transmission taking place, which introduces more RFI.
I prefer synchronous oversampling at the DAC. I like the 1990s DAC designs because in my opinion, they're truest to the music prior to A/D digitization.
