New Open BoxAudioengine D2 DAC Original MSRP $599Complete set with Sender and Receiver Wireless DAC (Digital to Analog Converter), all cords and connections, accessories, and packaging. All is new, but the packages are both unsealed. See pictures.Please research for further technical specification and make sure you want to purchase before bidding.OverviewThe D2 wireless system transmits bit-perfect PCM-stereo simultaneously to up to 3 receivers. This PCM stream is routed from/to the various components of the system (optical transmitter/receiver, USB controller, and DAC) via the I2S bus, which maintains data integrity throughout the system. Because the various source/sink components are segregated by the wireless subsystem, various anomalies which plague many wired DACs such as jitter, grounding, and induced cable noise are greatly reduced. In addition, the D2 allows the user to physically isolate a potentially noisy computer from the sensitive audio components in your system..
