1. D03K vs D3

A: The D03K is our new update to the D3.  The differences are as follows:1. Improved DAC circuitry for improved sonic performance.
2. Two line out ports on the D03K—RCA and 3.5mm.
3. To prevent noise output, the D03K will automatically mute if unsupported Dolby, DTS or other multichannel format input are detected.
