Most people aren't opposed to audio that sounds good, but gear can get expensive. When you move into streaming audio, you might as well think about pulling out a second mortgage. But NuForce thinks their Air DAC can bridge the gap between performance and price.
The NuForce doesn't use a wireless streaming standard like AirPlay or DLNA to push audio, but rather their own proprietary technology which requires a USB or 30-pin dongle. That's kind of a bummer, but it does make setup easier, and has a neat feature where a connected device will automatically switch over to the nearest receiver when in range.
The Air DAC receiver will cost $150 on its own, and you can get the USB and iOS dongles for $60 and $80, respectively. You can also get either in a bundle with the receiver for $180 and $200, respectively. Expect to see these available in March. [NuForce]
