I'd say any album that you are familiar with, regardless of the year it came out. What you have to learn is how your speakers sound. You could use Pink Floyd's original Dark Side of the Moon, Nelly's Country Grammar, or a Britney Spears album, but you have to know what it sounds like.
But to answer your question - Kanye West & Jay-Z: Watch The Throne (sonically one of the best albums ever)
