MODEL 40n
Integrated Stereo Amplifier with Streaming Built-In
Made at Shirakawa Audio Works, Japan
Digital heart, analog soul.
Marantz has reimagined the integrated amplifier for the digital age while preserving a luxurious analog feel and sound.
Model 40n is a masterpiece of audio architecture. Created with passion and built in Japan with extraordinary attention to detail, every element brings you closer to the music you love when you plug in your favourite speakers.

Digital Heart, Analog Soul
Each MODEL 40n is tuned by a Marantz Sound Master to deliver the most musical sound possible, with 70 watts of Class A/B amplification per channel to drive your favourite speakers.
HDMI ARC Input
Not every TV needs a full surround system, but every TV deserves great sound. The HDMI ARC (Audio Return Channel) input enables audio from your TV to play back through your stereo with the warmth and dimensionality you’ve come to love from Marantz. HDMI CEC is also included for easy control with your TV remote.
High-Resolution Digital Streaming Built-In
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, Bluetooth, Tidal, TuneIn, and more services—plus, playback of your own collection via USB-A input or on compatible home servers.
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.
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 favourite records and discover new ones, all without the burden of additional electronics.
Subwoofer Output
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.
Your sound preferences at your fingertips. Adjust bass and treble to suit your sound or bypass for the purest sound possible.
High-Resolution Audio Support
Modern high resolution audio playback is fully supported up to PCM 384kHz / 32 bit as well as DSD up to 5.6 MHz.
Make your home a musical oasis. MODEL 40n can be the primary stereo in your home or one of many–all connected by HEOS® technology.
External Control Capabilities and Custom Integration
MODEL 40n is a joy to use with its included remote control but can also be used with home integration systems such as Control4.
