The front of the MD3 features a round display that shows animated widgets and volume settings. The device includes both a 3.5 mm and a balanced 4.4 mm headphone jack on its bottom edge. An integrated amplifier uses four ESS ES9603Q chips and an ESS Sabre ES9039Q2M DAC to process audio up to 32-bit at 384 kHz. The amplifier delivers 80 mW through the 3.5 mm port and 180 mW through the balanced connection.

Rumors point to a global price of around $150 for the MD3 MagDac. The manufacturer has not yet officially confirmed the final pricing. The device is scheduled for launch on May 25th.
