A masterpiece of audio architecture

Created with passion and extraordinary attention to detail, every element brings you closer to the music you love.

  • Stream millions of hi-resolution songs: Stream from Spotify, Pandora, Tidal, and more or enjoy your own music file libraries. Works with Alexa, Google, and Siri.
  • Whole-Home Hi-Fi: Create a multiroom musical experience with the MODEL 40n as your home's music hub.
  • HDMI Input adds AV Connectivity: HDMI ARC (Audio Return Channel) adds uncommon flexibility to this stereo amplifier by enabling TV sound through your stereo.

Multiroom streaming with HEOS Built-in

Effortlessly connect via Bluetooth, Apple AirPlay 2, or directly from the HEOS app to play all your favorites from hundreds of streaming services.

High-Resolution Digital Streaming Built-In

MODEL 40n is for those whose music collection is infinite and online. Connect to your network with Wi-Fi or ethernet. With HEOS® Built-in, you won't need extra equipment to stream your favorite tunes. MODEL 40n supports Spotify, AirPlay 2, Apple Music, Bluetooth, TIDAL, TuneIn, and more services - plus, playback of your own collection via USB-A input or on compatible home servers. 

The Marantz Musical Phono EQ

The joy of vinyl playback is both audible and tactile yet requires highly specialized electronics for high performance. The Marantz Musical Phono EQ is built in so you can connect a turntable with MM cartridge directly to MODEL 40n. You'll enjoy your favorite records and discover new ones, all without the burden of additional electronics.

Precise Tone Control

Your sound preferences are at your fingertips. Adjust bass and treble to suit your sound or bypass for the purest sound possible.

Luxurious Look and Feel

MODEL 40n follows a long line of historic Marantz pieces notable for their exquisite design. Every aspect is considered - from premium materials, symmetry, classic porthole display, and even smooth operation of the volume control. Your stereo doesn't need to look like lab equipment. Marantz MODEL 40n begs to be heard, seen, and touched.

Hyper Dynamic Amplifier Modules

To preserve the detail, nuance, and essence of the music you love, Marantz developed HDAM (Hyper Dynamic Amplifier Modules) which are superior in their speed and response to off-the-shelf modules found in other products. MODEL 40n leverages this unique Marantz innovation to ensure whatever you're listening to is always the most musical.

Subwoofer Ouptut

Deep bass is a visceral and exciting sensation. When partnered with equally excellent speakers, MODEL 40n produces impressive bass. If you want more, add a subwoofer using the dedicated subwoofer output and dial in the low-frequency crossover settings and level for precise integration with your main loudspeakers.
