Actually, you did.
You need to be more precise with your language. You have posted multiple times now implying or flat out asserting that PlayStation 3 SACD rips go through some sort of convoluted DSD → PCM → DSD conversion. Using the well established method, the rips themselves are just raw data from SACDs. Any post processing applied to the rips, however, may entail PCM conversions.
The gist is that any SACD rip in ISO form is DSD directly off of the disc. Further evidence of this, the ISO may be even DST compressed DSD, and that lossless compression would be ridiculous to reapply after any PCM conversion.
But any random DSF file could be produced from any source or format. SACD, CD, MP3. All bets are off.
