Marantz is on a mission to reposition itself as a luxury hi-fi brand and is hoping its new Model 40n integrated amplifier will help drive the message home.

The Model 40n follows in the footsteps of the Model 30 launched back in 2020, but with one major difference. The 30 was purely a stereo amplifier, but its successor has streaming smarts built-in. The clue is the lower case 'n' which signifies it's more than happy to jump on your home network either wirelessly or via its Ethernet socket.

This functionality all comes courtesy of the built-in HEOS streaming platform which 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 AirPlay 2 and Bluetooth support are also included and you can even access the world of voice control via Amazon Alexa and Google Assistant.

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 record player and an ARC-compatible HDMI input for hooking the Model 40n up to a 4K TV. There's even a dedicated subwoofer output for extra flexibility should your set-up demand it.

As far as actual amplification is concerned, the Marantz Model 40n uses a Class A/B design with a total output of 70 watts per channel. Internally, all manner of things have been done to reduce the effects of outside interference, 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.

The Marantz Model 40n will be available in either Marantz Black or Silver Gold finishes and will cost $2499 / £2199 / AU$4499 / €2499 when it goes on sale in March.

    Is Hi-Res really going to sound much different on this when compared to my 25 year old Arcam7 ? I'd love to invest if there is a good reason. Thanks

    I don’t think any 25 year old anything - especially an Arcam - has any streaming capability. But if you’re asking about the amplifier side, that rather depends on which Arcam and which separate streamer you use. The Marantz is an all in one.

    I’m not sure it’s correct to call the 40n a sucessor to the 30, is it? For a start, the 30 is significantly more powerful and class D, while the streaming comes from the partnering streamer cum SACD player, the 30n.

    I currently have the Marantz 7000n and wondered if the 40n is really worth over twice the price - would it really be that much of an upgrade?

    Hi to the WhatHiFi comunity. I liked so much the review from the New marantz 40n. I wanted to now if it d be a good match with my kef ls50 meta which are a little difficult to drive in terms of power, since they are los sensitive speakers at 85db.

    I have exactly the system you are asking (Kef50 Meta + KC 62 + model 40n).

    I do not have other Intergrated amp to compare with, but I think this set up sounds very nice. If you like warm sound you can't go wrong with model 40n.

    One thing if you are using streaming services make sure they are in HEOS system. I used Tidal via Airplay 2 and HEOS, its quite obvious difference HEOS built in is much better.

    Hope you find this helpful.
