Quick Take: The Harman Kardon CP 25 is the middle of three component-based home-theater-in-a-box systems (HTIBs) in Harman Kardon's 2006 line and the most affordable of the company's packages to offer 7.1-channel surround sound. Like the other two CP models in Harman's product line, the CP 25 simply comprises an A/V receiver, a DVD player, and a surround speaker package that you could otherwise buy separately. However, these matching products are packaged together for convenience and include a single remote control. The advantage of component-based home-theater systems is that they tend to offer better sound quality, more features, and more flexibility (such as plenty of inputs and outputs to connect other A/V devices) than smaller "lifestyle friendly" systems. But unlike the lifestyle systems (such as Harman's own HS 100), the component-based systems are big and bulky, and they're intended for users with a bit more home-theater experience. Note that Harman's component-based HTIBs comprise products--such as the receivers--that are not necessarily the latest model the company offers.
Harman Kardon's most affordable HTIB is also its most attractive: this slick-looking system is anchored by an all-in-one receiver/amplifier/disc player that's not much bigger than your average DVD player.
