Marantz independently developed the HDAM analog amplifier circuit, which is generally only used in advanced or top-of-the-line computers. The practice of using cheap ICs was abandoned and replaced by its own HDAM (High Defintion Amplefer Module) module. The wide frequency response of HDAM (High Resolution Amplefer Module), low negative feedback, and high response rate greatly enhance the improvement of sound quality!
