I don't know diddly about how SACD works, so I can’t offer a technical opinion on that.
I can however tell you that the PS3 does a fantastic job at playing them. My Wee Oppo 970 has effectively been fired from that duty.
If you think your audio system sounds good now, just wait till you get to hear true uncompressed multi channel surround at 48kHz per channel. As much of an improvement that HD is over SD video, the jump in audio improvement is just as big.
I'm in orgasmic bliss watching HD content, with a 2.35 ratio set up and HD uncompressed audio. The only negative is my average of reading a book week is now a book every six months or so. My brain cells are shriveling up at an alarming rate.
