I don’t personal fancy DSD, and high-res or not depends on the recording. Many people like to upsample with something like HQPlayer and I’m quite sure I have read that you have recommended upsampling in a computer not long ago, lol. I don’t like to upsample in a computer, but nor will I criticize if others do. Failure of the design, I don’t know. If a recording is made in high-res with more real samples and more bits (IE more data) is it then not reasonable that this sound a bit better? What about MP3? A high res recording down mixed to 44.1 is not lossless just like a MP3 to 44.1.
