Beware of SACD Transports -- they probably will not work with your favorite DAC


Hello, I just learned a painful lesson. I'm guessing that not many people will know this so I'm going to put it in here.

The audio on a SACD is encrypted.
If I were to purchase a SACD / CD player I have nothing to worry about. The Audio is un-encrypted inside the player.
However if I were to purchase a SACD / CD Transport made my brand Z, I would have to purchase a brand Z DAC???
Apparently Sony who owns the SACD format mandated that the audio on the SACD itself is encrypted and
the digital output from a SACD transport is ALSO encrypted. It looks like the actual un-encryption is done in the DAC.
There is no standard for doing the un-encryption so every manufacturer has their own proprietary way of doing this.
So I cant use a Esoteric SACD transport and an Auralic DAC which is what I tried to do?

OP is correct. The only way to "free" an SACD for playback on any third-party DSD-capable DAC to is to rip it to a DSF file on an early Playstation or Oppo. Search the web for Ted’s SACD Ripping Guide.
Equipped with the software extensions outlined in Ted's guide, an early Playstation will convert an SACD into an ISO file on a USB stick.  Transferred a PC, this file may then be converted by Sonore's ISO2DSF freeware to the native rate of SACD as a DSF file.  The Sonore software captures all metadata and track sequencing.
