D-1 [better] | Marantz Project

Yet, in 1998, a legendary engineering group went against the grain. The same Japanese team at the Sagamihara facility responsible for iconic masterpieces like the Philips LHH900R introduced a statement piece under the Marantz banner: the . Limited to only 500 units worldwide , the Project D-1

Today, the Marantz Project D-1 remains a highly sought-after collector's item for those seeking the specific "analog-like" warmth of the R2R ladder DAC era. Marantz Project D-1 - Legendary Vintage DAC

Instead of relying on generic off-the-shelf digital filters, Marantz integrated a proprietary high-speed Digital Signal Processing (DSP) engine. This allowed for custom digital filtering algorithms that minimized pre- and post-ringing artifacts, preserving the critical phase relationships of the audio signal.

In the rapidly evolving world of high-fidelity audio, few components attain the status of a "classic." While modern DACs boast increasingly high sampling rates and DSD capabilities, a select few vintage digital-to-analog converters (DACs) from the 1990s are still revered for their musicality. Among these, the Marantz Project D-1

The rear panel features an exhaustive array of 7 digital inputs , including three BNC coaxial inputs, three TOSLINK optical inputs, and a professional AES/EBU XLR input. Marantz Project D-1 - Legendary Vintage DAC :

In the early 90s, Marantz set out to create a digital reference series that would define the brand's capabilities. While the CD-15 and CD-7 players are legendary, the Project D-1 was their statement piece in the standalone DAC market. It was designed as a companion to the Project T-1 vacuum tube drive, forming a digital playback system that challenged the best from manufacturers like Mark Levinson and Accuphase.

appeared on the scene, the digital audio world was shifting toward 20-bit, 24-bit, and high-sample-rate converters. However, Marantz designers recognized that early, well-implemented 16-bit multibit technology could offer a "musical," analog-like quality that many early, harsher-sounding delta-sigma designs lacked.

The digital circuits are laid out on a premium 4-layer board featuring thick inner copper traces, while the analog and power sections employ massive, gold-plated dual-sided boards with a total copper thickness of 135 microns to ensure flawless signal conductivity.
