Audiophile metal albums


What are some well recorded, great sounding metal albums?

I think Tool for sure. But looking for other examples, preferably with non-growling vocals.

Armored Saint - Win Hands Down                        The Sword - Warp Riders
We can argue whether ACDC is hard rock or metal but this one sounded real good on my system: Stiff Upper Lip (CD). Angus Young's Gibson SG playing was particularly striking for its drive and power! Speaking of power the newly-released one is called Power Up - and was produced as a tribute to the late Malcom Young!
@bajaed : Good point there! More songs about chasing blondes wearing short shorts would be welcome!

System of a Down (self titled) and SOAD Toxicity
Both excellent new vinyl releases
