Marantz CD6007 Finely Tuned Network Streamer CD Player - B-Stock Marantz HDAM Technology Marantz CD6007 developed its own discrete circuit boards to replace standard ICs. These HDAMs consist of discrete surface mount components with short mirror image L/R signal paths. These devices do exactly the same thing as the Op-Amps but outperform the regular IC Op-amps dramatically in terms of the Slew Rate and reduced noise level, resulting in more dynamic, accurate and detailed sound. In the CD6007, the proprietary HDAM-SA2 circuit improves on its previous HDAM module for a more stable power supply. The idling current stability is less influenced by power transistor temperatures to maintain sound performance even at high level output. Reference Quality D/A Conversion The Marantz CD6007 features a new Hi-Res D/A conversion. It is equipped with a reference class AK4490 D/A converter, offering two selectable filter options, and provides up to 192-kHz/24-bit and DSD 5.6MHz resolution for optimum musical fidelity with tight bass, pleasant mids and smooth extended highs for CD playback and Hi-Res formats from USB memory stick. High Current Power Supply The audio power supply employs high speed, high current Shottky Barrier Diodes and new higher value current storage capacitors compared to the previous model. The size of the power supply capacitors has been increased by 120% for improved current stability and reduced AC noise during high demanding listening sessions. High Slew Rate Op-Amp + HDAM-SA2 Compared to the CD6006, the Marantz CD6007 offers an improved and redesigned headphone amplifier section. The CD6007 inherits the exclusive Marantz HDAM-SA2 circuit with three gain settings (Low/Mid/High) for a perfect match with almost any brand of headphones for an optimal solo listening experience.
