Marantz CD 50n Network CD Player - Black

The CD 50n sits at the heart of Marantz's current disc player range, positioned above the CD 60 — a dedicated CD player without streaming or DAC functionality — and below the SACD 30n, which adds SACD playback and the higher-specification HDAM SA3 output stage with Marantz Musical Mastering. Where the CD 50n distinguishes itself is in combining CD playback, network streaming, and a full USB DAC section with HDMI ARC connectivity — a feature unique to this model within the Marantz lineup.

Amplification & DAC Architecture

The analogue output stage uses Marantz's proprietary HDAM (Hyper Dynamic Amplifier Module) in the low-pass filter stage, paired with HDAM SA2 modules in the output buffer. This discrete component approach avoids the compromises of integrated op-amps by using surface-mount transistors in a current-feedback topology, delivering wider bandwidth and faster slew rates than conventional designs. The headphone amplifier shares the same HDAM SA2 architecture, maintaining signal quality through to the front-panel output.

A DAC Master Clock Design reduces jitter by positioning the master clock directly adjacent to the DAC, minimising trace lengths and electromagnetic interference. The circuit layout is symmetrical, with separated rectifier circuits for the analogue and digital sections fed from a toroidal power transformer. Two selectable digital filters — part of Marantz's Musical Digital Filtering — allow listeners to tailor the transient response to their preference.

Network Streaming & Connectivity

HEOS Built-in provides access to Spotify Connect, TIDAL, Deezer, Amazon Music, and TuneIn Internet Radio over Wi-Fi (2.4 GHz and 5 GHz) or wired Ethernet. AirPlay 2 is supported for Apple device streaming, and Bluetooth is available for both receiving and transmitting audio. The unit is Roon Tested for integration with Roon music management software. Hi-res streaming supports FLAC and WAV up to 192 kHz/24-bit, ALAC up to 96 kHz/24-bit, and DSD, with gapless playback on FLAC, WAV, and DSD streams.

The rear-panel USB Type-B input operates in asynchronous mode for bit-perfect transfer from a computer, supporting PCM up to 192 kHz/24-bit and DSD up to 11.2 MHz (DSD256) via DoP. A signal isolator separates the DAC circuitry from the USB interface when operating in DAC mode, reducing noise coupling from the source device. Digital optical and coaxial inputs and outputs (one of each) accept signals up to 192 kHz/24-bit, and a single HDMI ARC input allows the CD 50n to serve as a DAC for a connected television.

CD Transport & Construction

The disc mechanism plays CD, CD-R, and CD-RW media with support for CD-Text metadata display. The chassis is reinforced with a double-layer metal plate (2 × 1 mm) to dampen vibration and improve structural rigidity. A three-line OLED display on the front panel shows track information, source, and format data, with dimmer and display-off modes to minimise electrical noise from the display circuitry during playback.

The variable RCA output with volume control — adjustable via the supplied remote or the HEOS app — enables the CD 50n to drive a power amplifier directly without a separate preamplifier. Control integration options include RS-232, IP control, D-Bus, and a flasher input for custom installation environments.
