Marantz CD 3577 (1989) | Class DX One-Bit Conversion for Pure Digital Sound

 

The Marantz CD 3577 marks a true breakthrough in CD player technology. Instead of relying on a traditional Digital-to-Analog Converter (DAC) with its resistor-based limitations, the CD 3577 uses advanced Class DX one-bit conversion to deliver cleaner, more accurate sound. Conventional DACs can introduce zero-cross distortion and low-level non-linearity, especially when processing small audio signals. The CD 3577 eliminates these issues by converting PCM data into Pulse Width Modulation (PWM) using an ultra-high 256× oversampling digital filter. A precision quartz-controlled timing system and a third-order noise shaper push unwanted noise far above the audible range, resulting in exceptional clarity and a superior signal-to-noise ratio. The result is audio that sounds more natural, transparent, and detailed, especially in the subtle low-level information where musical texture and space live. The Marantz CD 3577 reveals the true character of your recordings with accuracy that conventional DAC designs cannot match. The CD 3577 was also a unique model, part of the Century Collection, an ensemble that brings together the most desirable audio and video features into a synergistic group.
