Exactly. There are certain Sony Blu Ray Players and the PS 3 if it is under the 3.55 firmware I believe… I may be wrong but I believe the recordings are DSD recorded to SACD. With the rip of the SACD it becomes the .dff, dsf, or iso. All of which can be played via DSD playable Dacs that can then decode then decode the ripped formats. Sacd, .dff ,dsf. For me the choice is the .dfs since it captures the metadata. I’m still trying tolearn and understand this more.
An excellent source which I accidently stumbled into was at the Hi Fi Haven Forum
@Mikey Fresh, one of the moderators has an excellent step by step directions. It wasn’t easy for me to learn. Of course when I learned enough to at least start ripping Stereo and now Multi Channels it was easier for me.
Hence the expression is easy once you learn it. If you get a chance visit this link. http://www.hifihaven.org/index.php?threads/rip-sacd-with-a-blu-ray-player.3652/
It is a wonderful source to get up and running so one can archive there Sacds.
Lastly I can’t say enough how @MikeyFresh took time and walked me through the times I got stuck . It was a wonderful experience when I burned my first one. The link I mentioned will show you which Sony Blu Ray Players you can find on Ebay, in many cases for $25-$30 delivered.
