Marantz Project D-1 Work Jun 2026

A built to preserve perfect phase alignment and high transient snap.

The problem it solves is subtle but profound. The peak recording levels on CDs vary wildly. A pop CD from the late 1990s might be mastered "hot" (close to digital maximum), while a classical recording from the 1980s might be mastered at a much lower average level, effectively wasting many of the 16 bits available. marantz project d-1

The internal architecture features heavy copper plating and dedicated shielding compartments. This physical separation prevents the high-frequency noise generated by the digital processing stages from bleeding into the sensitive analog output stages. A built to preserve perfect phase alignment and

Features a massive, low-impedance 250VA-class power transformer housed in a dedicated shielding can to eliminate electromagnetic interference. A pop CD from the late 1990s might

High-speed 10A fast-recovery diodes paired with custom, low-impedance chemical capacitors connected in parallel for instant current delivery.

They found a compromise in modularity. The D-1 shipped as a core unit with standard inputs and outputs, and optional expansion modules—one focused on analog inputs and phono preamps for vinyl enthusiasts, another on networked streaming, and a miniature tube-stage add-on for those seeking a more overt tube coloration. The modular approach kept the base price manageable while preserving customization.
