More suggestions: What about the Rocky series? The original mixes of all five are on the Blu-rays, but they are (of course) lossy.
There are PCM versions of the original mixes (mono for I, Dolby for II-IV) on the 1990 MGM/UA releases of I-IV (black covers with the image in the center). And there's only one LD release of V, which has PCM too.
