Sound quality characteristics: sound field and its loose, background transparent, high frequency delicate and not hard, intermediate frequency plump, low frequency elasticity is strong, and the tone is biased towards vinyl records!
Marantz independently developed the HDAM analog amplifier circuit, which is generally only used in advanced or top-of-the-line machines. The practice of using cheap 1C is abandoned, and its own HDAM (High Defintion Amplefer Module) module is replaced. The wide frequency response of HDAM (High Resolution Amplefer Module), low negative feedback, and high response rate greatly improve the sound quality.
