The was not a standalone player. It was designed as a duo: The Project D-1 DAC coupled with the Project D-1 transport (often referred to as the CD-12 or the standalone transport unit). Together, they formed a "cost-no-object" digital front end. While the transport is revered for its die-cast chassis, the DAC remains the more intriguing piece of the puzzle.

While the transport is revered for its die-cast
This is where the D-1 loses some listeners. It is not "airy." It rolls off the extreme high frequencies gently. If you are used to the hyper-detailed sound of MQA or DSD, the D-1 will sound dark . However, that darkness translates to zero fatigue. You can listen to the D-1 for 14 hours straight without a headache.
