High-resolution network streaming and CD playback with HEOS Built-in, HDAM circuitry, USB DAC, HDMI ARC, and variable analog outputs

The Marantz CD 50n combines a high-performance CD player, network audio streamer, and sophisticated digital-to-analog converter in a single component. Designed for music enthusiasts who want to enjoy their CD collections alongside modern digital music sources, the CD 50n offers extensive connectivity, high-resolution playback, and the proprietary analog circuitry for which Marantz is known.

Part of the Marantz 50 Series, the CD 50n brings together traditional hi-fi engineering and modern streaming technology. With HEOS Built-in, Apple AirPlay 2, Bluetooth, Spotify Connect, HDMI ARC, and multiple digital inputs, it can serve as the primary digital source in a complete music system. Fixed and variable analog outputs also allow it to connect to an integrated amplifier, preamplifier, or power amplifier.

High-Performance CD Playback

At the heart of the CD 50n is a modern digital audio engine designed to extract fine detail from conventional compact discs. Compatible with CD and CD-R/RW media, the player combines precise digital signal processing with Marantz's proprietary analog circuitry to deliver a refined and engaging listening experience.

The CD 50n uses a high-accuracy DAC master clock design to maintain precise timing during digital-to-analog conversion. Careful selection of audio components and an optimized signal path help preserve musical detail, dynamic contrasts, and stereo imaging.

Marantz's Sound Master tuning process also plays an important role in the CD 50n's performance. Through component selection and extensive listening evaluations, Marantz engineers refine the player's sonic character to achieve the company's preferred balance of detail, warmth, and spaciousness.

In addition to conventional audio CDs, the CD 50n supports compatible MP3 and WMA files on recordable discs. It does not play SACDs, and DSD, WAV, and ALAC data discs are not supported. High-resolution music files in these formats can instead be accessed through compatible USB or network sources.

Marantz HDAM Technology

Rather than relying exclusively on conventional integrated-circuit operational amplifiers, Marantz uses its proprietary Hyper Dynamic Amplifier Modules (HDAM) in the CD 50n's analog circuitry. These discrete amplifier circuits are designed to provide high slew rates, wide bandwidth, and rapid response to changes in the musical signal.

The CD 50n incorporates HDAM circuitry in its low-pass filter stage and HDAM-SA2 technology in its output buffer. These circuits handle the analog signal following digital-to-analog conversion, helping maintain signal integrity and preserve fine musical detail.

The analog circuitry benefits from a symmetrical layout, carefully selected components, and separate rectifier circuits for the digital and analog sections. These design choices help minimize interference and provide stable operating conditions for the sensitive audio circuitry.

High-Resolution Music Streaming With HEOS

With HEOS Built-in, the CD 50n provides convenient access to music streaming services, internet radio, and locally stored digital music. The HEOS app allows listeners to browse music, select sources, adjust volume, and control playback from a smartphone or tablet. Supported services include Amazon Music, TIDAL, Spotify, Pandora, Deezer, and others, with availability varying by region.

For listeners with their own digital music libraries, the CD 50n supports high-resolution PCM files up to 24-bit/192 kHz and DSD files up to 11.2 MHz through compatible network sources. Music can be played from network-attached storage devices, computers on the local network, or compatible USB storage devices.

Gapless playback is supported for FLAC, WAV, and DSD files, allowing continuous recordings such as live albums and classical performances to play without unwanted interruptions between tracks.

Apple AirPlay 2 makes it easy to stream directly from an iPhone, iPad, or Mac, while Bluetooth provides a convenient wireless connection for compatible devices. Spotify Connect offers direct control of Spotify playback from the Spotify app, and TuneIn provides access to internet radio stations.

Multiroom Audio Made Simple

The CD 50n can also be part of a larger HEOS multiroom audio system. Connect additional HEOS-enabled Marantz or Denon components throughout the home, and use the HEOS app to play different music in different rooms or synchronize playback across multiple listening areas.

Listeners can control the CD 50n and other HEOS devices through the same app, making it easy to expand a traditional stereo system into a whole-home music system without replacing existing amplification or loudspeakers.

The CD 50n is also Roon Tested, providing another way to integrate the player into a music system managed through Roon.

A High-Resolution DAC for External Sources

In addition to playing CDs and streaming music, the CD 50n can function as a standalone digital-to-analog converter for external components. Its rear-panel USB-B input accepts audio from a compatible computer, while optical and coaxial digital inputs accommodate CD transports, digital audio players, and other sources.

The asynchronous USB-B input supports PCM audio up to 32-bit/384 kHz and DSD up to 11.2 MHz. By using the player's own precision clock rather than relying on the computer's timing, asynchronous USB operation helps reduce the influence of timing errors during digital audio transmission.

A dedicated signal isolator helps protect the sensitive DAC circuitry from electrical noise associated with a connected computer. Optical and coaxial inputs support PCM audio up to 24-bit/192 kHz.

Marantz Musical Digital Filtering provides two selectable digital filter settings for PCM playback. These allow listeners to choose between different digital reconstruction characteristics according to their preferences and the rest of their audio system.

Better TV Sound With HDMI ARC

The CD 50n also offers HDMI ARC connectivity, allowing audio from a compatible television to be played through a conventional stereo system. This provides a convenient alternative to a soundbar, using the performance of dedicated hi-fi amplification and loudspeakers for television programs, movies, and games.

With a single HDMI connection from a television's ARC-compatible port, the CD 50n can receive television audio and deliver it through its analog outputs to an amplifier or directly to a compatible power amplifier.

HDMI-CEC support allows compatible television remotes to control volume and power functions, simplifying everyday operation. This makes the CD 50n particularly useful in systems that combine serious music listening with television entertainment.

Built-In Digital Preamplifier

The CD 50n includes both fixed-level and variable-level stereo RCA analog outputs, providing flexibility when integrating the player into different systems. The fixed outputs are ideal for connection to a conventional integrated amplifier or preamplifier, while the variable outputs allow the CD 50n to serve as a digital preamplifier.

With the variable outputs connected directly to a power amplifier, listeners can adjust volume through HEOS or the supplied remote control. This eliminates the need for a separate preamplifier in systems built around digital sources.

The combination of CD playback, network streaming, external DAC inputs, and variable analog outputs makes the CD 50n an especially versatile centerpiece for a streamlined two-channel audio system.

Dedicated Headphone Amplifier

The CD 50n includes a dedicated headphone amplifier incorporating Marantz HDAM-SA2 circuitry and a current-feedback design. This allows listeners to enjoy CDs, streaming music, and connected digital sources through headphones without requiring a separate headphone amplifier.

A front-panel headphone output and dedicated volume control make private listening convenient, while the carefully designed amplifier circuitry is intended to preserve the detail and dynamics of the music.

Premium Power Supply and Mechanical Construction

The CD 50n uses a toroidal power transformer, selected for its efficient power delivery and suitability for high-performance audio circuitry. Separate rectifier circuits for the digital and analog sections help reduce interference between the player's processing and amplification stages.

Internally, the player uses a symmetrical circuit layout, specially selected audio components, and additional chassis reinforcement. A double-layer metal plate strengthens the chassis and helps provide a stable mechanical foundation for the disc mechanism and sensitive audio circuits.

The substantial enclosure features a metal front panel and Marantz's distinctive contemporary design, with a circular display and symmetrical controls. Available in black or silver-gold finishes, the CD 50n is designed to complement other components in the Marantz 50 Series, including the MODEL 50 integrated amplifier.

Flexible Connectivity and Everyday Operation

Along with its wireless and network features, the CD 50n provides optical and coaxial digital inputs and outputs, a USB-B computer audio input, USB storage playback, and HDMI ARC. Gold-plated RCA connections are provided for both fixed-level and variable-level analog output.

Wired Ethernet and dual-band Wi-Fi provide flexible network connectivity, while an RS-232C port, flasher input, and IP control capabilities make the CD 50n suitable for custom installations.

A three-line OLED display provides clear playback information, with dimmer and off settings for listeners who prefer minimal visual distraction.
