Ripping SACDs the right way

FYI
As you may know recently I've proved that PS3 SACD ripping method is bit perfect. When we were having a PS3 ripping issue with the Guano Apes SACD on another forum a DSD capture was done through playing / capturing the DSD audio stream of this SACD on a modded Pioneer DV-989 DVD player. That time the PS3 ripping issue of this SACD was solved and the two rips could be compared. Having checked the respective DSD data in a HexEditor a forum member found the rips identical. Based on this finding I'm guessing that the Sonoma ripping method is also bit perfect. I'd be pleased if I could help in proving that (if necessary at all).

Not necessary... I'm happy with my results, as are my clients.

Besides, you never had the original files to test. Plus, you compared a stamped disc with a burned disc. Too many variables. Great first post!! :rolleyes:

Yes, the original audio files might be different. However, I don't think that the cutting master differs from the rip, provided proper works are done through the production and ripping line.

The Sonoma creates non-interleaved files. Never heard from anyone what they wanted!

What format are these files?

I think all that mansr wants is a snippet of a dsf track coming from the Sonoma rip to compare with the PS3 ripped and dsf'd file. Just 30 secs would do, mansr can align whatever portion it is and do a bit-for-bit comparison after alignment.

Exactly. Either DSF or DFF will do. I'm mostly curious about that apparent fade-in at the start of the Sonoma capture.

Surely, that reinforces his conclusions. Even with the many variables, the two resulting files were identical.

Exactly. The fact that the original DSD file might be different from the mastered data on the disc is irrelevant in this comparison. The entirety of the question is very simple: Is the Sonoma rip bit-identical when music is playing to the PS3 rip - that's it - simple question with a simple non-disputable scientific answer.

If Bruce can provide the snippet to mansr we can check if this is true or not.

Having said this, all the evidence here (from the bit comparisons done by grill) plus others I've seen in other forums indicate the PS3 rips are indeed bit-perfect. To me the question is settled.

Bruce: I have no doubt your clients are satisfied with your work. What doesn't seem to hold is the claim that the Sonoma produces accurate rips while the PS3 does not.
