We just launched a redesigned header. While the overall look is the same, we changed the drop-down menus to point to our top-level topic categories (Audio, Home Theater, Car Audio, etc) and corresponding sub-categories.
When you're within each category there are new tabs for (Reviews, News, Articles, New Products, Review Links) to filter content within the current page.
The changes were made to correct alignment issues noticeable on smaller screens (e.g. iPhone, iPad), but more importantly we hope you'll think it's easier to navigate the site.
