When it comes to getting audio from a PC via its USB port, the buzzword du jour is asynchronous. This cryptic term refers to which device has control over the timing of the audio data being streamed from the computer: the computer itself, or the device receiving the data. It might seem logical to have the computer control the timing, but this is not so. When digital audio data are converted to analog by a D/A converter, control over exactly when each dataword is converted is critical for the best quality of sound. Any uncertainty in that timing manifests itself as analog distortion, aka jitter.

It was three or four years ago, at a CEDIA Expo, that I first happened upon Advanced Dynamic Audio Monitors, aka ADAM Audio. What grabbed me was the array of imposingly high-tech speakers comprising their elite Tensor line. Sitting out in the middle of the floor of the Atlanta Convention Center, they not only looked more advanced than anything else around, they had the audacity to sound superb in a totally inappropriate acoustic situation. Despite the surrounding busyness of the Expo, I was able to sit down and actually enjoy the Beatles' Love on DVD-Audio. Clearly, these guys knew what they were doing. I vowed to follow up on it.
