Harman Kardon You'll feel surrounded by surround sound choices with Harman Kardon's AVR 520. The receiver decodes Dolby Digital and DTS 5.1- and 6.1-channel soundtracks, including DTS-ES Discrete. You'll need an outboard amp if you have one or two back surround speakers, though, as there are only five powered channels, rated to deliver 75 watts each into 8 ohms.

Panasonic With portable music players, the question is, how small can you get? About 1 5/8 x 1 3/4 x 5/8 inch, according to Panasonic, whose SV-SD80 digital audio player, shown larger-than-life below, weighs less than an ounce. It uses postage-stamp-size Secure Digital (SD) memory cards and can play music encoded in the MP3, WMA, and AAC formats.

Sony

Rated to deliver 110 watts of power to each of six channels, Sony's STR-DA5ES digital surround receiver is ready for 6.1-channel DVD soundtracks. If you're torn between DVD-Audio and Super Audio CD, the receiver's two sets of multichannel analog audio inputs let you hook up both at once, and one set can even handle 6.1-channel sources.

SONY

Pushing the upper size limits of a cathode-ray tube (CRT), Sony's 40-inch KV-40XBR700 Wega is the largest direct-view CRT set on the market. It's also an HDTV monitor and has two wideband component-video inputs, 2:3 (also called 3:2) pulldown capability to improve the look of film-based material, and aspect ratio control.

JVC

Prep for the future with JVC's RX-9010VBK digital surround receiver. Rated to deliver 120 watts to each of five channels, it has such forward-looking features as a front-panel USB port and an extended frequency response, rated from 7 Hz to 50 kHz ±3 dB, to handle the wider bandwidth of DVD-Audio.
