dsx

Back at CES 2010, we got a look at the Sony DSX-S100, a car stereo that distinguished itself with a feature called the Tune Tray--a sort of tiny, built-in glove compartment for stashing your portable media player of choice. Sony announced Thursday that it's adding two more Tune Tray models to its Xplod line of car stereos: the DSX-S200X and the DSX-S300BT.

The DSX-S200X inherits all the features of the DSX-S100, including a monochromatic OLED display, the all-important Tune Tray with its internal USB connection, and the omission of a CD player. The S200X then adds a second USB … Read more

I've reviewed many Denon receivers, but never one of the really big ones. Richard Ames, that lucky devil, had the pleasure of putting the Denon AVR-4810CI through its paces for "Home Entertainment" magazine.

Each of the receiver's nine channels puts out 140 watts. Just about every surround format is on board, including Dolby ProLogic IIz height channel processing and Audyssey's DSX (which adds the possibility of width channels as well). You also get Audyssey's MultEQ XT 8-point room correction processing.

Video signals, regardless of resolution or input, can be upconverted/transcoded to HDMI and … Read more

Those awful glasses may doom 3D TV.

What with all the advances in technology they still haven't eliminated the glasses people have been using to watch 3D movies since the 1920s. "Avatar" and "Alice in Wonderland" may use vastly more refined 3D techniques, but the glasses remain. Some people get headaches, dizzy, or even nauseated watching 3D. There are exceptions, but most 3D films haven't matured past the gimmick stage.

No matter how you look at it, 3D TV is an expensive proposition. You'll need to buy a new Blu-ray player, new TV, and possibly a new receiver. Oh, and don't forget to factor in the cost for extra 3D glasses for family and friends.

Worse yet, after you've made the substantial investment in new hardware there's not a lot of 3D content to buy or see. Put those bucks in better-sounding speakers, and you'll have a vast assortment of choices to dazzle your ears right away. Surround sound may be imperfect, but you can hear it with just your own two ears; no special "ear goggles" are required.

So instead of investing in 3D TV, take those dollars and buy better speakers or a new receiver. That's an improvement you hear with every movie you watch and music you listen to. It's simply a smarter way to spend your money.

What is 3D sound? True 3D sound would involve height, width, and depth speakers. Stereo sound produces width, and surround speakers produce depth. What about height? My experiences with the only available height systems--Dolby Pro Logic IIz and Audyssey DSX--didn't do much for me, but I'm not giving up on the height dimension entirely. Pro Logic IIz and Audyssey DSX were designed to work with any surround movie. Maybe we'll have to wait for movies mixed to provide genuine height information to get three-dimensional sound.… Read more

I'm a big proponent of stereo home theater, but I'd quickly concede that most home theater buyers are looking for multichannel systems. Of all the available multichannel options--11.1, 9.1, 7.1, 6.1, and 5.1 --that last one is the most popular, but that hasn't stopped most manufacturers from only offering 7.1-channel models. Budget-priced models are the only 5.1 receivers you can buy.

And in 2009, Dolby Pro-Logic IIz, which featured two additional "height" channels, bumped the total for some receivers to 9.1 channels, even though our listening tests here at CNET … Read more
