Some people seem to think that Malcolm Addey is an EMI/Blue Note employee; he's not, and as far as I know he did not remaster any Blue Note recordings in the 1500, 1600, 4000 and 4100 series. He did however remaster recordings that are now owned by EMI/Blue Note, like, for instance, the Randy Weston Mosaic. Addey has his own studio in New York City.
(Edited to specify which Blue Note recordings I was referring to)
