No one said home theater has to be complicated. Certainly not NAD, whose L 53 integrated DVD player/receiver combines two key components into a single, simple package. Made for places where surround speakers aren't an option, the L 53 has a stereo amplifier rated to deliver 50 watts to each channel and uses SRS virtual surround sound processing to add dimension to movie soundtracks. There's an optical digital audio output in case you want to connect an external Dolby Digital or DTS decoder. The player/receiver has a progressive-scan video output and comes with a backlit learning remote. Price: $599. nadelectronics.com, 781-784-8586
Plug-and-play satellite radio tuners can shuttle between your car and your home system, but if you still want to listen when you're not close to either, a transportable boombox like Cambridge SoundWorks' PlayDockXM will ensure you're never parted from your heavenly streams. The player acts as a docking station exclusively for XM radio's Roady and Roady2 tuners. Outdoors, the high-gain antenna attached to the 13-pound boombox should do just fine, but 20 feet of antenna cable is supplied in case you can't get a clear line of sight to the satellite. You can set the speaker drivers to Wide mode for a more spacious stereo image, and a 4-inch woofer helps take things down low. The built-in rechargeable battery is said to last 10 hours.
