Pink Floyd's Division Bell in 5.1 is very good. One of my recent favourite 5.1 releases is the Bob Marley Legend (30th Ann. Edition - not the HFPA stereo only one released here in AU as it sufferes from audio compression/loudness).
Thanks for the credit Snoopy8 - actually I wrote the code to generate the poll results page on the QQ link you posted above
If you cant see the effects of dynamically floating whites, dynamically floating blacks and dynamically changing gamma of low native contrast LCD with FALD enhancement dont go looking for it.
High end Plasma doesn't need any of that BS due to its VASTLY higher native contrast and produces a much more consistent and accurate picture. That doesn't mean people cant be very satisfied with LCD, most are not tuned into the finer points of image quality.
