Marantz Model 40n Streaming Amplifier

Finally. The evolutionary new Marantz Model 40n integrated amplifier drives the message home for this quality hi-fi brand 

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.

Bravo. Built like an audiophile amplifier

As far as actual amplification is concerned, the Marantz Model 40n uses a Class A/B analog design with a total output of 70 watts per channel. Internally, all manner of things have been done to optimise signal flow and reduce distortion and noise, from separating the power supply and audio circuits (pre/power stages, analogue and digital stages) with a heatsink, to using short signal paths and extra strong shielding to keep the signal as pure as possible for ultimate sound clarity.


Now with HDMI arc compatible input to hook up your 4K TV - but the connectivity doesn't stop there. You have a full assortment of analogue and digital connections to take advantage of too, including optical and coaxial digital, three analogue inputs, a moving magnet phono stage for your turntable. There's even a dedicated subwoofer output for extra flexibility should your set-up demand it.


The built-in HEOS streaming platform not only brings Spotify Connect, Amazon Music and Tidal to the party but also opens up your own digital music library with support for high-resolution audio to the tune of 24-bit/192kHz (PCM) and DSD up to 5.6MHz. Apple Music is also catered for with AirPlay 2 and Bluetooth support are also included—plus, playback of your own PC music file collection via USB-A input or on compatible home servers. You can even access the world of voice control via Amazon Alexa and Google Assistant.

Marantz Model 40 wins the Europe EISA Award

"Marantz’s rich history contains many landmark amplifiers, and the Model 40n ties perfectly into that heritage. Yes, it’s gorgeous to look at in either black or silver gold finish, but more appealing still is how it fuses the brand’s performance-first ethos with a dizzying range of features. Stream digital music via the HEOS platform, connect a turntable to the MM phono input, or lace up a TV through HDMI ARC – the Model 40n is equally at home playing your analog or digital music collection as taking TV and movie entertainment to new heights. Anyone seeking a modern, do-it-all integrated amplifier with superb sound will find it here"

Marantz Model 40 is awarded Stereophile Recommended Component  

"The Model 40n is a remote-controlled, network-connected integrated amplifier with a complete set of digital and analog inputs, including Wi-Fi, HDMI-ARC, USB, and MM phono, and can be controlled with the HEOS app.

Specified continuous output power is 70Wpc into 8 ohms and 100Wpc into 4 ohms. Compared with his reference Benchmark and NAD amplifiers, KR noted that the 40n was marginally warmer with vocals. Overall, however, he found that the Marantz's frequency balance was neutral, with tight, clean bass, an open-sounding midrange, and an extended, unstressed treble. The Model 40n "incorporates everything needed for playback from any source; just supply speakers and cables," KR concluded. "The 40n is this century's answer to the AM/FM stereo receiver of the previous one."

JA found that the Marantz offered excellent measured performance with all its inputs and exceeded its specified powers, clipping at 74Wpc into 8 ohms and 120Wpc into 4 ohms. However, the headphone output's high source impedance means that it is best suited to high-impedance 'phones like Sennheisers. (Vol.45 No.8 WWW)"
