Query: Recording/Engineering Quality Renders this Album Nearly Unlistenable

I'm not sure if it is because of the cd being an Anniversary reissue or what but it sounds like the orchestra was being recorded in a vacuum. The sound of the recording is muddy and suppressed and thus renders the music inaccessible. One of the other two reviewers remarked on this aspect earlier but seemed to downplay the significance. This is not to remark negatively on the mastery of the conductor Ander Previn or on the Royal Philharmonic. It just so happens with some classical recordings that no matter how brilliant the intrepretation (which strikes me as average for the symphony 4), a flawed production can be the ruination of any album.
