Performance

The Cinema 40 isn’t just about the spec sheet; it’s about how those specs translate into performance. Marantz has long been known for its warm and musical sound signature, and the Cinema 40 builds on that legacy with aplomb.

Audio Performance

Stereo and Music Listening

When it comes to two-channel stereo performance, the Cinema 40 shines. Thanks to the HDAM circuitry and current feedback topology, it delivers exceptional clarity, spatial separation, and depth. Vocals are articulate, bass is taut without overwhelming, and the soundstage feels expansive.

Surround Sound Immersion

The 9.4 channel setup, with support for up to 11.4 processing, creates an incredibly immersive surround environment. Whether you’re watching a Dolby Atmos-encoded blockbuster or a DTS:X Pro concert Blu-ray, the spatial rendering is pinpoint accurate. Overhead effects are convincing, side-to-side pans are smooth, and the entire room is enveloped in sound.

Subwoofer Management

With four independent subwoofer outputs, bass response is smoother and more balanced across the listening area. This is especially beneficial in large rooms or oddly shaped spaces, where single subwoofers often result in uneven bass.

Video Quality

If you’re running a cutting-edge 4K or 8K display, the Cinema 40 won’t bottleneck your experience. It supports all the latest HDR formats — including Dolby Vision and HDR10+ — and handles fast-action scenes brilliantly. Gamers will particularly appreciate the 4K/120Hz support and variable refresh rate features, which virtually eliminate lag and screen tearing.

Room Calibration and Setup

The inclusion of Audyssey MultEQ XT32 allows for detailed room correction. It calibrates speaker distances, crossovers, and levels with remarkable accuracy, correcting anomalies in room acoustics. The GUI is intuitive, and you can also tweak settings further via the Audyssey Editor App for precision control.
