Marantz HDAM Technology
Marantz 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.
