Since 2007, Audio Advice Live has been an annual, one-night event, drawing enthusiastic audiophiles to the Audio Advice showrooms in Raleigh's Glenwood Avenue, next to Virgin Cigars, or to their location in Charlotte. But this year, Audio Advice Live was different: It was a fully fledged audio show, held like most such events at a conference hotel: the Sheraton Raleigh Hotel, in that North Carolina city, with rooms sponsored and presented by a wide range of hi-fi (and home-theater) companies. The show's website listed 70 brands—58 home audio brands, the others video-related—followed by a graphic saying "+ MANY MORE!"
