They are very different masterings IIRC. The 1st stand-alone HFPA blu-ray is squashed to hell. I'm pretty sure the 30th blu-ray stereo has full dynamics - although I think I only listened to the stereo program once since I bought it for the 5.1. The CD of the 30th set is also squashed but I don't think it is the same mastering as the HFPA because the DR's are too different (the CD's DRs are about 2 higher across the board. I initially received the HFPA in error in instead of the 30th. I opened it up before putting 2+2 together but I noticed right away that the stereo section sounded wrong and was completely baffled when I couldn't find the 5.1 program. Edit: I'm taking this back now that I'm digging back in my memory. I actually think the HFPA and the 30th blu-ray stereo are the same. There are so many versions of Legend that I'm getting them confused. So IIRC, HFPA 2.0 = 30th 24/96 2.0, however the 30th 16/44 2.0 is not the same (but not great either). Only buy the 30th for the 5.1 (which is excellent and sounds great).
