Logitech Squeezebox Duet

Once you have the Duet configured to work with your network, you have lots of musical playback choices. The Duet handles most audio formats that you can think of, including standard fare such as MP3, AAC, and Ogg Vorbis; lossless formats such as FLAC and Apple Lossless; and uncompressed formats such as .wav and AIFF. The Duet's one gaping hole: It won't play files with any sort of digital rights management protection.

In addition to streaming music from your PC, the Duet will also connect with numerous online music sources, including services such as Rhapsody, Pandora, and Slacker, plus Internet radio stations. If you don't already have accounts, you can sign up for premium services through squeezenetwork.com, a site associated with your Duet.

The Web service still has some kinks to work out. The squeezenetwork.com site had some bugs when I used it, for example. I attempted to sign up for Pandora, filling out all the required boxes, and when I clicked submit I received an error message that said, literally, "BLAH BLAH." Not exceptionally helpful. I successfully signed up for Last.fm, but once I did so, I couldn't find any way to play the service through the Duet.

Using the Duet's controller to navigate the playback options is mostly a pleasure. The navigation makes sense, and the 2.4-inch color screen gives you lots of room to see your choices. Once you decide on an album to play, you can view the album's cover art. The display features crystal-clear text, though you do get what you pay for (the screen is neither as large nor as bright and luxurious as the screen on the Sonos controller).

I have a few gripes about the Duet, which came up in the course of my testing. While playback was often faultless, at times the Duet would fail to play a song or cut out in the middle of a song. The system would report that it was still connected to my wireless network, but it would be unable to play a song on my PC, even though it may have played the same song a few minutes before.

In addition, the scroll wheel on the controller is not as responsive as those you'll find on an iPod: Getting to the exact menu item I was interested in was frequently frustrating. I also experienced long lag times between pressing a button and seeing a result. Some of the delays occurred when the system was dealing with resources on the Web, and so the lag may be attributed to latency on the Net. Other times, however, something as simple as changing the volume took a few seconds to kick in.

Overall, this is an elegant system that's simple to set up and use, and it offers a reasonably priced alternative to high-end products such as the Sonos Digital Music System. But its habit of cutting out or failing to play a song can be extremely annoying.
