The Marantz Project D-1: Japan’s Secret Masterpiece That Time Almost Forgot

When you hear the name "Marantz," most people picture the iconic silver-faced receivers of the 1970s (like the 2270) or the luxurious modern Reference series. But tucked away in the dark corner of 1990s high-end audio lies a strange, beautiful anomaly: The Marantz Project D-1.
