Come on Sony, Make DSD big
Sony killed off DSD / SACD a few years ago. The 5400ES was probably the last dedicated SACD player they will ever make. A few boutique labels do release DSD / SACDs on a limited basis, but there's only so much re-issued Brahms or Mahler one can handle.
Mic'ing, mixing, mastering, i.e. audio production/engineering techniques, will determine SQ much more than any final delivery format will. SACD tends to sound better because the masters are usually better than the original CDs or recently remastered CDs; the latter tends to sound horrible with massive compression and extra brightness added.
For most people, DSD shouldn't be a factor. Unless you are one of those few who have substantial SACDs ripped via a hacked Sony Playstation 3.
