Marantz CINEMA 40: High-End 9.4-Channel AV Receiver with Real Hi-Fi Power

Some AV receivers are boxes you hide in a cabinet. The CINEMA 40 is the kind you show off. It’s big, confident, beautifully built—and it sounds like Marantz took everything they know about music and cinema and turned the dial all the way up.

This is a 9.4-channel powerhouse pushing 125 real hi-fi watts per channel, wrapped in brushed aluminum with that unmistakable round Marantz display glowing back at you. It doesn’t shout for attention.

Lift it, and you’ll immediately understand where the money went—this thing is dense, solid, and built to last years of movie nights and long listening sessions.

It’s the rare AV receiver that actually makes your living room look better.

The “Most Musical Sound” isn’t marketing fluff

Marantz has been talking about The Most Musical Sound for decades—and the CINEMA 40 proves they still mean it. Yes, it can shake the room with explosions and thunder, but what really sets it apart is how human it sounds.

Music flows. Vocals feel warm and present. Guitars have body. Piano notes hang in the air. Even at low volumes, there’s emotion and texture instead of thin, lifeless sound. If you love movies and actually care about music, this receiver hits a sweet spot many competitors miss.

In terms of design, function and sound quality, you get everything your heart could desire, and you can look forward to many years of proud ownership and unforgettable audio experiences, whether home cinema or music is on the menu.

Power that’s calm, controlled—and seriously underrated

On paper it’s “125 watts.” In reality, it’s much more than that. Marantz measures power the honest way—full bandwidth, real-world conditions. Compare it to brands using marketing-friendly numbers and the CINEMA 40 suddenly looks very muscular.

Inside, you’ll find:

9 identical amplifier channels
Separate power supplies for analog and digital sections
Custom capacitors and heavy-duty output transistors

The result? Effortless dynamics, deep bass control, and zero sense of strain—even when things get loud.

The CINEMA 40 is a heavyweight that demands its space. But it's also a beautiful piece of industrial art that can become a visually exciting element in your living room, instead of just a big anonymous metal box. — The CINEMA 40 is a heavyweight that demands its space.

HDAM: the secret sauce

Instead of cheap op-amps, Marantz uses its own HDAM (Hyper Dynamic Amplifier Modules)—discrete amplifier circuits hand-tuned by Marantz’s Sound Master. This is where the magic happens.

HDAM delivers:

Faster response
Lower noise
More life and punch

Even the built-in phono stage gets the HDAM treatment, meaning your turntable doesn’t feel like an afterthought. Vinyl lovers, you’re covered.

You also get two selectable sound filters:

Mode 1: smooth, relaxed, classic Marantz warmth
Mode 2: sharper, faster, more analytical

Choose with your ears. Both are excellent.

HDMI 2.1 everywhere – gamers, relax

Seven HDMI 2.1 inputs. Three outputs. Full 8K support. 4K/120Hz. VRR, ALLM, QFT. eARC. Done.

Whether you’re running a PS5, Xbox Series X, high-end PC, projector, TV—or all of the above—the CINEMA 40 just works. One cable to the TV, pristine picture, and full Dolby Atmos sound back through eARC. No drama. No compromises.

The simple and stylish aluminum front is dominated by the golden Marantz logo and the iconic round display, while secondary buttons and the main display are hidden behind an aluminum hatch.

Dolby Atmos, DTS:X, Auro-3D… and then some

This receiver speaks every modern surround language fluently:

Dolby Atmos
DTS:X
Auro-3D
IMAX Enhanced

Out of the box, you can run up to 7.4.2 or 5.4.4 without external amps. Add more amplification and you can push even further. Four subwoofers? No problem. Ceiling speakers? Go wild.

You want cinema realism? This thing delivers it in layers.

No FM radio here—and you won’t miss it. Instead, you get HEOS multi-room, Wi-Fi, AirPlay 2, Spotify Connect, Bluetooth (two-way!), and voice control via Google Assistant or Siri.

Music from Spotify, Apple Music, Tidal, internet radio, your NAS—it’s all there, all easy, all stable. HEOS is fast, intuitive, and surprisingly audiophile-friendly.

Setup that doesn’t make you swear

Marantz deserves credit here. The setup wizard is clear, logical, and actually helpful. Speaker terminals are horizontal and color-coded. You can save two different speaker presets. Switch between movie night and late-night listening with one button.

Room correction? You get Audyssey MultEQ XT32 with proper multi-sub calibration. Want more? Upgrade to Dirac Live and go full control-freak.

And yes—there are neighbor-friendly modes for late evenings when the house is quiet but the movie isn’t.
