The Marantz CD-7 is a compact disc player that epitomizes a return to classic multibit digital processing, specifically leveraging the Philips TDA1541A DAC in a unique 'Double Gold Crown' variant for enhanced audio performance. Designed by Ken Ishiwata, the player integrates advanced technologies like a bespoke MZ777f digital Linear Music Filter, which features emulation of Philips' conventional filtering methods with switchable algorithms. The transport mechanism is a custom-refined CDM12.3, crafted to enhance reliability and performance. With a solid build, the CD-7 features 14 Marantz HDAM op-amps, a filtered power supply utilizing Shottky diodes, and an anti-resonant chassis designed for sound integrity. Additionally, it supports balanced XLR outputs, RCA outputs, and offers both optical and coaxial digital outputs, alongside a digital input allowing it to function as a DAC. The player showcases a frequency range of 2Hz to 20kHz, with a dynamic range exceeding 98dB and a signal-to-noise ratio of over 102dB. Although the CD-7 excels in midband performance, providing a rich and engaging listening experience, it has been noted for its somewhat limited soundstage. It boasts a luxurious design with a champagne gold aesthetic, complemented by a tactile remote control. The overall audio signature is described as musical and dynamic, appealing particularly to users who prioritize rhythm and engagement in their listening experience.
