We haven’t auditioned many cheap speaker systems lately. Why? Well, let’s just say we don’t enjoy subjecting our ears to the sonic equivalent of waterboarding. But Logitech has a knack for packing big sound into inexpensive boxes, so we agreed to review its new two-channel Z520 system.

You’ll have to decide for yourself if the Z520 system’s $130 price tag really puts it in the “cheap” category, and we imagine the folks at Logitech will cringe to hear us describe them as such; but you can cut only so many corners before we begin to ask, “Why bother?” Judging by these speakers’ performance, Logitech’s engineers know just how low they can go.
 
When we see small speakers, we usually pigeon-hole them as near-field monitors: short-throw speakers that produce a small stereo soundstage that collapses as soon as you move more than three feet away from the cabinets. There’s nothing inherently wrong with near-fields, especially in a PC environment, but they have their limitations. So we were surprised to hear Logitech boast that the Z520 could provide a “great listening experience throughout the room.” We decided to put that claim to the test as soon as we took the speakers out of the box.

There’s no good reason for the existence of Asus’s Xonar HDAV 1.3 Slim soundcard, and yet it’s a godsend for those of us who want to hear the high-definition soundtracks on so many of the Hollywood movies released on Blu-ray disc. Blame Microsoft for the contradiction: No one would need a product like this if Vista provided a protected audio path.

After all, this card doesn’t decode Dolby TrueHD or DTS-HD Master Audio soundtracks, nor does it enhance the audio or the video; it just passes the signals through to your A/V receiver. Using the included HDMI cable, the card takes the output from your videocard, re-encrypts the soundtrack so that no one can intercept the bit stream to make a bit-perfect copy, and outputs the encrypted audio and video to a second HDMI port. For those without HDMI, Asus also includes a DVI-to-HDMI cable.

The protected audio path requires a software component, too, so Asus bundles a copy of ArcSoft’s TotalMedia Theatre with the Xonar. Not your favorite media player? Too bad, it’s the only one that’s compatible. For what it’s worth, we don’t have any complaints about the program. There’s nothing objectionable about its user interface; it can handle all the major codecs; and it supports BD-Live, so you can access whatever online content is linked to the movie you’re watching.

By launching a full line of music-streaming products, including the Director DMC250 reviewed here, Cisco clearly has the Sonos Digital Music System in its sights; unfortunately, it’s fallen well short of the target.

Our biggest complaint has to do with the convoluted setup process, which includes installing Cisco’s LELA (Linksys EasyLink Advisor) on at least one PC. LELA isn’t a bad utility—if you’re completely terrified by the prospect of setting up a home network. If you’re an old hand, it’s a waste of computer resources.

The default installation also forces you to set up a user account on Cisco’s website. A spokesperson tells us this is because Cisco needs to act as an intermediary between you and Rhapsody. Really? What if you already have an account with Rhapsody? What if you decide you don’t want anything to do with it? There’s apparently some way of installing the Cisco media server software without LELA or divulging your email address to Cisco, but the documentation doesn’t mention it.

D-Link’s DIR-685 Wi-Fi router generated a lot of buzz at CES this past January. And when we took a gander at its spec sheet, we thought it a contender for Best of the Best in the router category; something that would finally displace the Linksys WRT600N, which is becoming hard to find. Alas, ’twas not to be.

The problem certainly isn’t with the DIR-685’s feature set: This router is absolutely loaded with goodies. The 3.2-inch color LCD can inform you of the router’s status and configuration; present digital photos from Flickr, Picasa, and Facebook; display RSS feeds, such as sports scores, weather reports, and stock quotes; and a lot more (this is one router your significant other won’t insist be hidden in a closet).

Next up, there’s a 2.5-inch internal SATA hard drive bay, which can turn the router into a NAS box (complemented by a built-in FTP server and BitTorrent software). There are two USB ports featuring D-Link’s SharePort technology, which allows you to plug in both an external hard drive and a printer and share these devices with any computer on the network. The router’s four-port gigabit switch automatically powers down any ports not in use to save a modest amount of energy.

DirectX 10 marked a radical departure from DirectX 9: In order to be compatible, a graphics processor must feature a unified architecture in which each shader unit is capable of executing pixel-, vertex-, and geometry-shader instructions. The changes in DirectX 11 aren’t quite as fundamental, but they could have just as big an impact—and not only with games.
 
DirectX 11 is a superset of DirectX 10, so everything in DirectX 10 is included in the new collection of APIs. In addition, DX11 offers several new features and three additional stages to the Direct3D rendering pipeline: the Hull Shader, the Tessellator, and the Domain Shader. And in an effort to deliver cross-hardware support for general-purpose computing on graphics processors, Microsoft has come up with a new Compute Shader.

DirectX 11 will be compatible with both Vista and Windows 7, but many of its graphics features will be available on GPUs designed for previous iterations of Direct3D. Tapping into the Tessellator’s power, however, will require a GPU with transistors dedicated to the task (in this sense, DX11 marks a slight departure from DX10’s vision of a unified architecture). Let’s explore the concept of tessellation now.

With 802.11n Draft 2.0 routers becoming as common as Storm Troopers at Comic-Con, manufacturers need a feature that sets their product apart from the crowd. Like many of its competitors, Belkin added a second radio to its N+ Wireless Router—but this one is used for a very different purpose.

Rather than operating on a separate frequency (to separate audio and video streams from more mundane data), the second 2.4GHz radio on Belkin’s router establishes a guest network that limits clients to Internet access. Belkin’s web interface provides extremely limited access to this second radio’s settings: You can turn this radio on or off, change its SSID and passphrase, and choose between WPA/WPA2 pre-shared key or “Hotel Style” security.
