Sony’s Super Audio CD (SACD) is an audiophile format featuring high resolution and multi-channel sound. The discs are are copy protected, and until now it has not been possible to create an exact copy. Of course you can capture the analogue output and re-digitise it, and certain players from manufacturers such as Oppo enable you to capture digital output converted from Sony’s DSD (Direct Stream Digital) format to high-resolution PCM (Pulse-Code Modulation); but still, it is not an exact copy.
Ripping an SACD is still not that easy. The crack depends on getting hold of an early model of the PlayStation 3 that has not been updated to the latest firmware. Recent PS3s do not play SACD at all, plus you need firmware of 3.55 or lower, before Sony removed the capability of running an alternative operating system. There is no downgrade path, so it is a matter of scouring eBay for one that has not been updated.
Once you have the right hardware you can follow the instructions here to rip the SACD:
SACD-Ripper supports the following output formats:
– 2ch DSDIFF (DSD)
– 2ch DSDIFF (DST) (if already DST encoded)
– 2ch DSF (DSD)
– mch DSDIFF (DSD)
– mch DSDIFF (DST)
– mch DSF (DSD)
– ISO (due to the 4GB FAT32 size limit on the PS3, files will be splitted when larger)
There is some discussion of the procedure here from where I have grabbed this image:
Is it worth it? Good question. There are SACD enthusiasts who swear that DSD reproduces sound with a natural fidelity that PCM cannot match. On the other hand, researchers conducted a test showing that listeners could not tell the difference if the output from SACD was converted to CD standard PCM. I have also seen papers suggesting that DSD is inferior to PCM and may colour the sound. Expect heated opinions if you enter this debate.
Nevertheless, there are many great sounding SACDs out there and the format is not completely dead. Universal Japan, for example, issues SACDs made of SHM (Super High Material) at premium prices, and whether it is thanks to the super super technology, or simply clean mastering from good tape sources, these are proving popular within the niche audiophile market.
The fact that these discs cannot be perfectly ripped is part of the appeal from the industry’s perspective. Now that is no longer the case, and the torrent sites will be able to offer DSD files with full SACD quality.
