OK, so I diffed the 24 and 16 bit versions of Come Together. First observation: these come from the same digital master. There is zero sample rate difference between them (ie the samples all line up perfectly - not possible if they were from different masters).
Second observation: the overall null is -82dB (so in 16-bit terms the difference is in the bottom 3 bits). The difference file sounds silent until you give it 50dB of boost - then you can hear broadband noise (hiss) plus the basics of the music itself - you can follow the words!. Interestingly the hi-hats are very clear... Looking at the diff file frequency plot, the differences are all below 500Hz or above 15kHz. In between there is little difference. Conclusion: the files are very similar but still different. The differences should be audible on good equipment. The differences should manifest themselves at the top end (hi-hats) and possibly in the bass guitar/drums. The 24-bit masters are worth having - certainly Abbey Road is. -- Phil Leigh You want to see the signal path BEFORE it gets onto a CD/vinyl...it ain't what you'd call minimal...
