Audioengine D2 is a simple to use yet powerful digital-to-analog converter with performance and features generally found in much more expensive DACs plus it is wireless. The D2 processes digital audio at any bit depth up to 24 bits and sample rates to 192KHz, then sends your music over-the-air at 24/96. It accepts USB or PCM-stereo optical and will automatically configure to match either of these inputs. 

The D2 is actually three products in one - a high-quality USB wireless computer DAC, a wireless USB-to-SPDIF converter, and a wireless optical PCM-to-stereo link. The ability to stream HD audio wirelessly from the computer direct to a music system not only keeps the computer away from an audio gear, but also minimizes nagging problems such as ground loops, induced cable noise, and jitter. The D2 can provide bit-perfect wireless USB-to-SPDIF conversion or serve as a wireless link to a PCM-stereo stream from any existing DAC.
