Marantz AV10 15.4 Channel 8K AV Processor Review Roundup

If you’re a home theater enthusiast in constant pursuit of uncompromised audio and video performance, the Marantz AV10 Processor merits your attention. This reference-grade 15.4-channel, 8K AV processor offers a harmonious blend of advanced technology, meticulous design, and exceptional sound quality, poised to transport you into a realm of cinematic brilliance.

Design, Construction, and Aesthetics

The Marantz AV10 Processor is not just a marvel of audio engineering but also a testament to meticulous craftsmanship and construction. To achieve its lofty sound quality standard, the AV10 has been designed with the utmost attention to detail.

Three-Layer Aluminium Chassis and Polycarbonate Feet: The AV10 features a robust three-layer aluminum chassis that forms the foundation of its construction. This chassis design serves a dual purpose – it provides structural integrity and serves as an effective shield against internal vibrations. The processor is also equipped with polycarbonate feet, which further isolate it from external disturbances, ensuring a pristine audio experience.

Copper Grounding Plate: To maintain a low impedance and the cleanest signal path, Marantz has incorporated a copper grounding plate into the AV10’s construction. This plate ensures that the audio signal remains unadulterated as it travels through the processor.

Separation of Analogue and Digital Sections: Inside the AV10, the analog and digital sections have been thoughtfully separated. This separation is critical to maintaining audio purity, preventing interference, and ensuring that each section operates optimally.

Main Features

The Marantz AV10 Processor’s excellence extends beyond its construction. Here are some of the main features that set it apart as a reference-level component:

Dolby Atmos, DTS:X Pro, Auro 3D, and IMAX Enhanced: Driving the digital side of the board is the Griffin Lite XP DSP Digital Signal Processor. Chosen for its processing power, this DSP enables the AV10 to handle up to fifteen channels and four independent subwoofer outputs. It also decodes all formats, including Dolby Atmos, DTS:X Pro, Auro-3D, IMAX Enhanced, and MPEG-H Audio.  This processor supports the most immersive audio formats available, providing a three-dimensional audio experience that will transport you into the heart of your favorite movies and music.

HEOS Built-in Streaming: Enjoy the convenience of streaming music from popular services like Spotify, TIDAL, and more, all integrated seamlessly into your home theater setup.

Ten 32-Bit ESS 9018 DACs: Digital signals must be converted to analog for your listening pleasure. The AV10 achieves this with precision, employing ten 32-bit hi-fi-grade stereo ESS 9018 DACs. To further enhance audio quality, channel allocation has been meticulously considered, ensuring that more active channels share a DAC with less active channels, minimizing channel crosstalk.

Crystal Low-Phase Noise Master Clock: To eliminate timing artifacts such as jitter, the AV10 relies on a precise crystal low-phase noise master clock.

HDAM3 Technology: Marantz’s proprietary HDAM3 technology plays a crucial role in the analog stage, delivering clarity and precision.

Redesigned Preamplifier Circuit Board: The preamplifier circuit board has undergone a redesign, adopting a four-layer or quad design. With the analog, digital, and power circuitry occupying different board layers, this design reduces noise and significantly enhances overall clarity.

Toroidal Power Transformer: The AV10 features a toroidal power transformer with low impedance OFC winding, ensuring a stable and clean power supply.

Linear Power Supply: Housed in an aluminum case and resting upon an aluminum base plate, the linear power supply further contributes to the processor’s clean power delivery.

Sound Master Voicing: The final voicing of the AV10 was meticulously performed by Marantz’s Sound Master, Yoshinori Ogata. His expertise resulted in an expansive soundstage with an excellent sense of width, depth, and height, accompanied by a high level of focus and detail. The AV10 boasts fast and tight bass, providing an audio experience that truly transcends expectations.

Advanced Room Correction: The AV10 Processor incorporates two powerful room correction technologies:

  • Audyssey MultEQ XT32: This sophisticated room calibration system measures and corrects for imperfections in your listening area, ensuring that audio is finely tuned to your specific room dimensions.
  • Dirac Live Room Correction (Paid Upgrade): For those seeking even more precise room correction, the AV10 offers Dirac Live as a paid upgrade. Dirac Live takes room calibration to the next level, providing a detailed analysis of your listening environment and making real-time adjustments for optimal sound quality.
