Can ACS10 rip DSD files from SACDs?

No. It is not possible to extract DSD files from SACDs with a normal optical CD drive. This can only be done with special equipment which defeats SACD encryption technology. When ripping SACDs, ACS will rip the stereo "red book" layer of your hybrid SACDs. It cannot rip single-layer SACDs which can only be played in an SACD player.
