Anything by Deep Purple Mk II. All I've found was trashed or overpriced.
Scott Joplin: Piano Rags by Joshua Rifkin.
Anything by Ennio Morricone. His music deserves a Mobile Fidelity treatment.
And a bunch of movies soundtracks. Bullit, The Magnificent Seven, Star Wars, The Sting, A Clockwork Orange, and stuff like that from the 60's and the 70's.
