The SDAC-B is equipped with the AKM AK4452 digital-to-analog conversion chip from the same family as the one used in the m9XX DAC/amp, our first collaboration with Grace Design. On the back panel, you’ll find a balanced output, three-pin XLR outputs, and a coaxial SPDIF digital input, which will allow the DAC to interface with balanced amplifiers and single-ended amplifiers at the same time. The three-pin XLR outputs also give you the ability to connect to powered speakers and use software volume control. On past projects, the community has been vocal about wanting a USB-B connector, so we added one to the SDAC-B, too!
