Several Metallica recordings have gotten butchered/botched by the mastering guy on crack. It's unfortunate indeed. I've had to go to great lengths to salvage some Metallica, Maiden, Testament, etc.. their recordings.
If you're looking for a surprisingly high quality metal recording to test a hifi rig (for metal that is, in recent times), get the hirez master for a fairly new, but seemingly popular indian folk metal band called "Bloodywood". The album's name appears to be "Rakshak".
(Crank it up and don't forget to fasten the seatbelt on this one)
Opeth (Swedish prog metal band) is another decent option that didn't get all their recordings butchered by mastering guy on crack.
