A CD player and network audio player with HEOS streaming, a USB DAC and HDMI ARC for TV sound. The Marantz CD 50n uses HDAM circuitry, Marantz Musical Digital Filtering and a dedicated CD transport.
It is part of Marantz's 50 series and comes in black or silver-gold. Marantz says it brings all your digital audio into one component.
Why you will love it
CD playback and a built-in DAC
It plays CD and CD-R/RW discs, along with MP3 and WMA files, and has a front USB input for memory sticks. For CDs, Marantz lists a 100dB dynamic range, 112dB signal to noise ratio and 0.0016% THD.
The DAC inputs are USB-B, optical, coaxial and HDMI ARC. Marantz lists a rear USB-B input with asynchronous mode, bit-perfect transmission and DSD up to 11.2MHz, and a Marantz Windows driver is available.

Streaming with HEOS
HEOS built in streams from services including Spotify Connect, TIDAL, Deezer, Amazon Music and TuneIn radio, and controls multiple rooms from the HEOS app. AirPlay 2, Bluetooth and Roon (tested) are supported, and it plays FLAC, WAV and ALAC files to 192kHz/24-bit and ALAC to 96kHz/24-bit, plus DSD, with gapless playback of FLAC, WAV and DSD.
Wi-Fi supports 2.4GHz and 5GHz, and there is an Ethernet port.
HDAM circuitry and Musical Digital Filtering
The low-pass filter stage uses HDAM, with HDAM SA2 on the output buffer and headphone amplifier. Marantz also lists a toroidal transformer, separate rectifier circuits for analogue and digital sections, and a double-layer metal plate to strengthen the chassis.
Two selectable digital filters let you choose between two sound characters. HDMI ARC carries TV sound over one cable, and the built-in digital preamp lets you control volume from the remote or HEOS app when driving a power amplifier.
