Audioengine D2 Premium 24-Bit Wireless DAC allows you to stream wireless HD audio from your computer to any music system, independent of your Wi-Fi network. D2 includes USB and optical inputs, a high-performance DAC, plus the isolation benefits of wireless. Setup is fast and simple, with no software to install and without the frustration of trying to connect to your network.
Are there any audiophile nerds who can comment on this? Is this essentially a wireless version of the D1?
