Home Theater Receiver Information

About.com's Robert Silva has created a great guide to home theater audio, explaining the different options and technologies, along with some historical information that puts everything into context. (Note: ConsumerSearch is owned by About.com, but the two don't share an editorial affiliation).

Understanding Surround Formats at Practical-Home-Theater-Guide.com includes a thorough explanation of the alphabet soup of surround-sound formats used today. Both Dolby and DTS formats are discussed, including high-definition audio formats.
