Foobar2000 does have a plugin, but it only lets you play an ISO image, which has to be made using an older playstation (newer firmware killed the capability) and with some software plugin/mod.
It works well. But for hard copy, you may have a much tougher time. I've tried playing my SACDs on my VAIO Laptop PC, which is equipped with the original OptiArc Blu Ray disc drive, and no luck. I've done a fair amount of reading, and so far, it's pretty much unanimous: Unless you own an older VAIO desktop version PC, it just won't happen. Something about the laser's lens focal length makes most drive incapable of reading the SACD layer, though some might "Detect" a DVD, starting software to read it will yield failure.
