Premium Marantz Model 40n – Review & Specs

The Marantz Model 40n integrated stereo amplifier provides the best sound quality possible from all of your audio sources. This device’s center is an excellent amplifier with analog and digital inputs. All of your favorite services, including Spotify, TIDAL, Apple Music, and Amazon Prime Music, are accessible thanks to the wi-fi, Bluetooth, and AirPlay 2 built in. DLNA-compatible network streaming is also available, as well as Internet radio with vTuner.

Superior audio quality thanks to HDAM

Marantz’s unique HDAM-SA3 (Hyper-Dynamic Amplifier Module) circuits are used in the high-end amplifier. Surface-mount metal-film resistors are used in these custom op-amps to improve temperature stability. The end result is a sound that is delivered with crystal clarity and is cleaner and less distorted.

The Marantz Model 40n amplifier provides enough power for room-filling sound with a convenient 70 watts per channel. The double insulated, toroidal power transformer contributes to the continuous power, low noise, and silent operation of this Marantz amplifier, making it ideal for hearing every nuance of your favorite music.

For the full networking experience, Bluetooth, AirPlay 2, DLNA, and built-in wi-fi are included.
It’s simple to connect all of your smartphones, tablets, and compatible laptops and desktops using Bluetooth and AirPlay 2 connectivity and play music wirelessly. Furthermore, the Model 40n has DLNA, WiFi, and Internet radio.
To access thousands of Internet radio stations via vTuner and subscription services like Spotify Connect (Premium Spotify account required), Tidal, Deezer, and Amazon Prime Music, simply connect to your home network over Ethernet or wi-fi. You can stream from additional devices, like your laptop or NAS drive, if they are DLNA compatible.

Using Alexa, Google Assistant, and Siri devices for voice control
The Model 40n is compatible with Amazon Alexa, Google Assistant, and Siri devices for the most recent in smart home technology. Simply ask Alexa or the Google Assistant to carry out fundamental tasks after downloading the HEOS Home Entertainment Skill app. Siri voice control over the Apple Home App from an Apple iOS device offers more capability than AirPlay 2, including the ability to group devices.
Marantz claims that the Model 40n’s linear power supply and massive, double-shielded toroidal transformer, designed to produce high current on demand, make it an excellent match for speakers that are challenging to drive.

The Marantz Model 40n amplifier supports only moving-magnet cartridges, but does so with two amplification stages, which is claimed to reduce gain and distortion, in contrast to the Model 30 integrated amp’s phono stage, which supports both moving coil and moving magnet cartridges.

The best multi-room audio is available with HEOS built-in
HEOS multi-room music systems are simple to set up with your existing home network because they are connected by dual-band Wi-Fi. Even the largest homes may be covered for multi-room music with the ability to put up up to 32 HEOS devices at once. The Model 40n is equipped with HEOS and can function as a single “zone” without the need for any additional adapters.
Control everything via the HEOS app
Once your HEOS speaker system is set up, you may stream music with ease using the specialized HEOS app. The application, which is compatible with Apple iOS, Android, and Amazon Kindle, allows you to stream not only your stored music but also Internet channels and well-known streaming services like Spotify, Tidal, Pandora and Deezer.

The Marantz Model 40n amplifier is adaptable enough to fit everything from your TV to turntable in addition to the extensive network streaming choices. There is an HDMI with ARC for TV. The optical and coaxial digital inputs are used to connect to game consoles and some other digital sources. For analogue sources, there are 3 RCA phonos and a recording output. Connect your deck to the phono input for the greatest vinyl.

High level of design

You can tell the Marantz Model 40n integrated stereo amplifier is well-built when you pick it up. The interior of the case is stuffed to the gills with digital connectivity, including HDMI and network streaming, coupled with an extensive MM phono stage, of course, being a feature-rich device. You may thank the toroidal transformer, the internal heatsink, and the necessary shielding between the DAC and phono components for the weight (almost 17kg). The front panel of the amp is made of strong, non-magnetic aluminum, while the top cover is made of steel to withstand mechanical and electrical interference. Even the aluminum power button is polished to the greatest standards, as are all the controls. Photo: Marantz
