In Reply to: Then why does HiRez PCM and DSD sound better than 16/44.1? posted by oldmkvi on February 9, 2015 at 08:09:52:
Filters are used in playback of digital files. If you upsample the important filters are in the computer, not in the DAC. Different filters sound different, so this is a sufficient explanation. (There are other considerations, but they will depend on specifics of the DAC.)
I use a Mytek Stereo192-DSD DAC. Upsampling 44 kHz to 176.4 is a big improvement, at least with some of the filters offered by HQPlayer. This is because the Mytek uses the stock filters in the SABRE chip and these are not so good. With this setup the results are further improved by upsampling to DSD128. Here there is the further issue that HQPlayer uses a different sigma-delta modulator than the Mytek, again an explanation for different sound. There are more complexities peculiar to an individual system. If the DAC (or software upsampler) doesn't filter out high frequency images and other trash this may or may not matter, depending on the analog components downstream of the DAC.
