Can't speak to the Turrentine set, but I recently picked up the Freddie Hubbard set that is part of this reissue series and the sonics are more than acceptable and a great and inexpensive way to pick up those classic recordings. IMO, the quality of the music trumps (sorry) any concerns re the sonics. Fantastic record:
