Textbook for macroeconomics (advanced undergrad) I find that many contemporary macroeconomics textbooks are too applied, filled with examples, case studies and intuitive illustrations, often at the expense of quantitative rigour and therefore the depth of the understanding they convey. 

Is there a canonical, quantitative textbook for central macroeconomic concepts and models? This should be preferably readable at an advanced undergraduate level.
Advanced Macroeconomics by David Romer, now in its fourth edition. Link contains TOC and a sample chapter.

The presentation consists of formal theory models, but with lots of intuition too, followed by light empirical applications.
