So enough has been said about this album in many other Amazon reviews. This is my favorite Pink Floyd album, although it didn't always hold this status. On first hearing, it can seem very dense and inaccessible, given the length of the three main tracks. But the old addage of "rewards repeated listens" certainly applies here. The only real knock is that Rick Wright seems missing-in-action on this record, a fact generally attributed to his heavy cocaine use during the recording of this record (and which would eventually lead to his outster after "The Wall" was recorded). So while I would rate "Wish You Were Here" a VERY close second, this remains the best PF album, IMO.
So....the big question is the sound quality. I owned the original CD pressing of this album, the 1992 box set version, the 1996 remaster, and now this version. My overall opinion is that there have been discernible improvements with every release, and this time is definitely no exception. The closest parallel I can think of is the Beatles' 2009 remaster campaign. This album, like those, seems to have a deeper sound, with more resolution around the bass end. The drums have a nice, throaty sound (most evident in the verse of "Pigs"), and I can definitely hear the bass line better now (and this is even more noticable on "Dark Side of the Moon," as an aside). During the acoustic portion of "Dogs," I swear I can hear the clicking of Gilmour's pick on the guitar strings. And the last verse of "Dogs" packs a bigger punch than on any version I can remember.
But with Pink Floyd, the silent parts are almost important as the notes they play, and it's here where I can really hear something different going on. Its the space BETWEEN the notes that sound really quiet and clean here, giving everything that much more punch with each drumbeat.
If you are an audiophile with even a modest setup, and if having the best version of the album is important to you, grab this release, and for $11.99 (at Best Buy), you will definitely not be disappointed. If you do most of your listening on an MP3 player at low encoding rates, the improvements here may be lost on you.
