The 30th anniversary and SACD were done by James Guthrie (Das Boot Studio) on ATC's (same as what Pink Floyd use). The orginal (back in '73?) was done by Alan Parsons (on B&W's?). Rather than spend $500 on a pressing it might be worthwile looking at your gear/room setup. (as Mike points out "as my system matured and improved the relative attraction of different pressings changed. ")
