Pink Floyd The Wall Remasters

With all of the different versions (remasters and imports) of The Wall, which version has the best sound? I believe there is a 1994 remaster and a 2000 remaster. Then there is the Japanese pressing among other import versions. The version I currantly have is a Columbia release and has 1997 on it. I love this recording and want to have it in all of its sonic glory. I would appriciate any thoughts toward this subject. Thanks.
