The Pink Floyd album "Dark Side of the Moon" on SACD has already been mentioned on this thread. Well, today I got my copy of the DSOTM "Immersion Box", which comes with a Blu-ray disc[*]. One of the things on this Blu-ray disc is the album (audio only) in 5.1 channel surround sound in 24 bits 96 kHz uncompressed PCM format.
It is quite stunning. Better, I would say, than the SACD.
[*It also comes with a scarf and some marbles.]
