Hmmm . . . surprised that two of my classic choices haven't been mentioned!
Pink Floyd's Dark Side Of The Moon (I prefer the Sony Mastersound only slightly over the 24 bit new stereo mix) and Welcome to the Machine (I prefer the new stereo remaster slightly over other versions). Magnificently recorded at the time, I have always used DSOTM as my classic rock test album for equipment.
Traffic's Low Sparks of High Heeled Boys remaster is also very nicely done and a great albums well!
