Marantz Model 40n Streaming Amplifier

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. 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 Model 40 is awarded Stereophile Recommended Component  

"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." read the review Stereophile
