AT A GLANCE
Powerful yet lightweight
Fast, HD onscreen menus
Limited audio streaming formats
Unfriendly DLNA streaming navigation
Surround-mode selection a bit clunky
A highly competitive audio and video performer in the kilobuck range, H/K’s AVR 3700 should do any home theater justice.
Harman/Kardon is among the quartet of major brands of American audio launched following World War II. (McIntosh, Marantz, and Sherwood are the others.) It’s further distinguished as the only one continuously retained by its owners as a U.S. company—though H/K today is just one brand of the sprawling Harman International empire. (History sidebar: During the Carter presidency, H/K was sold to Beatrice Foods while founder Sidney Harman served as Carter’s Under Secretary of Commerce; Harman then reacquired the company.)
