Super-Size It

A home theater is all about the big picture, and this Panasonic is as big as it gets. With a sprawling 103-inch screen, the TH-103PZ600U high-definition plasma is more than seven feet across. Just make sure the delivery crew puts it where you want it--it weighs 450 pounds.

You're Surrounded

Crank up the explosions. The Infinity Cascade's distinctive speaker drivers, composed of ceramic and aluminum, make for an uncompromising dynamic range and minimal distortion at even the highest volume levels. This is a surround system worthy of your action flicks.

Command Center

A receiver is what ties a home theater system together, powering the speakers and allowing you to easily switch between components. The Denon AVR-5805CI receiver is the crème de la crème. It can power two sound systems and toggle between five high-definition video sources.

Looking Sharp

Comparing the Denon DVD-5910CI with a $40 DVD player is like comparing a Ferrari with a Subaru. Sure, the Subaru will get you to the office, but it won't do much for your image. And image is what the DVD-5910CI excels at. It can bump a standard DVD up to full high-def quality, without a single jagged edge.

Don't Hate the Player

To deliver the most realistic game visuals yet, Sony's (NYSE:SNE) PlayStation 3 uses a new 550-megahertz, 300-million-transistor graphics chip. Best of all, you can use it to play the latest high-definition Blu-ray movies.

An HDTV's Best Friend

Though the high-definition DVD format war wages on, those with financial resources needn't be inconvenienced. Use the PS3 for Blu-ray and this Toshiba HD-XA1 for HD DVDs. High-def movies played on the Toshiba offer up to six times the picture detail of standard DVDs.
