Best sounding Hard Rock

Though it is not the main genre I listen to these days, I cut my teeth on the hard rock of the 70's and 80's.

I still like a good sesh of RTFOing, so it is with great delight that today I purchased Queens Of The Stoneage's Lullabies To Paralyze on vinyl.  The sound is beyond the pale.  It's a Music On Vinyl reissue, and is unbelievably quiet and smooth in tracking.  I am a fan of QOTSA but have never heard this album quite like this until now.

What are your picks for great sounding hard rock or metal?  My first preference is vinyl but this is by no means a requirement in your recommendations.
