The development of the AVR-X2900H and AVR-X3900H took place within the storied walls of Denon’s Kawasaki facility, where engineers have refined audio equipment for over a century. This latest iteration of the X Series is the result of a multi-year development cycle that prioritized mechanical isolation and a redesigned digital architecture. A central component of this upgrade is the integration of a new 32-bit eight-channel digital-to-analog converter (DAC) system. This hardware shift is intended to provide greater headroom and a lower noise floor, ensuring that even the most subtle auditory details in a film score or high-resolution audio track are preserved.
During the demonstration at the Kawasaki headquarters, the receivers were paired with Bowers & Wilkins 800 Series speakers in a 7.2.2-channel configuration. The objective was to showcase the receivers’ ability to handle extreme dynamic shifts—moving from whispered dialogue to thunderous low-frequency effects without losing clarity or introducing distortion. Engineers emphasized that the internal layout of the components was modified to shorten signal paths, thereby reducing the potential for signal degradation as audio travels from the input stage to the amplification blocks.
The AVR-X2900H: High Performance for the Mid-Range Market
The AVR-X2900H serves as an entry point into the premium home cinema experience, offering 95 watts per channel into 8 ohms. This power rating is sufficient to drive most consumer-grade floor-standing and bookshelf speakers with authority. The 7.2-channel architecture allows for a traditional 5.2.2 Dolby Atmos setup, incorporating two dedicated overhead or height channels to create a three-dimensional soundstage.
In terms of connectivity, the AVR-X2900H features six HDMI inputs, all of which support 8K/60Hz and 4K/120Hz passthrough. This makes the receiver fully compatible with the latest gaming consoles, such as the PlayStation 5 and Xbox Series X. The inclusion of Variable Refresh Rate (VRR), Auto Low Latency Mode (ALLM), and Quick Frame Transport (QFT) ensures a lag-free gaming experience. Additionally, the receiver supports HDR10+, Dolby Vision, and HLG, ensuring that the visual output matches the high-quality audio performance.
For music enthusiasts, the X2900H includes a built-in moving-magnet (MM) phono stage, allowing for a direct connection to a turntable. It also integrates seamlessly with the HEOS built-in platform, providing access to streaming services like Spotify, Tidal, and Amazon Music HD. The receiver is also Roon Ready, catering to audiophiles who utilize advanced library management software.
The AVR-X3900H: Expanding the Immersive Experience
For users with larger dedicated theater rooms, the AVR-X3900H offers a significant step up in processing and amplification power. With 105 watts per channel and 9.4 channels of onboard amplification, the unit can power a 5.4.4 or 7.4.2 Dolby Atmos configuration out of the box. Furthermore, the unit features 11.4 channels of processing, meaning users can add an external two-channel amplifier to expand the system to a full 7.4.4 setup.
A standout feature of the X3900H is the inclusion of four independent subwoofer outputs. This allows for precise bass management in complex room environments, reducing "dead zones" and ensuring that low-frequency energy is distributed evenly across the seating area. The receiver also adds support for AURO-3D, IMAX Enhanced, and Sony 360 Reality Audio, providing a comprehensive suite of immersive audio formats.
The X3900H is also built for the custom installation market. It includes 11.4 preamp outputs, allowing it to function as a high-end processor if the user decides to upgrade to more powerful external amplification in the future. This flexibility ensures that the receiver remains the heart of the system even as the user’s hardware preferences evolve.
Advanced Room Correction: Audyssey and Dirac Live
One of the most significant advancements in this generation of X Series receivers is the dual approach to room correction. Both the X2900H and X3900H come equipped with Audyssey MultEQ XT and XT32, respectively. This software uses a calibrated microphone to analyze the room’s acoustics and apply digital filters to compensate for architectural anomalies.
However, Denon has also continued its partnership with Dirac Research. For the first time at this price tier, users can purchase a license to use Dirac Live, a professional-grade room correction suite favored by high-end cinema installers. The AVR-X3900H goes a step further by offering compatibility with Dirac Live ART (Active Room Treatment), a cutting-edge technology that uses the system’s speakers to actively cancel out unwanted room resonances. This level of acoustic control was previously reserved for receivers and processors costing significantly more.
Integration and the HEOS Ecosystem
Central to the utility of the new X Series is the HEOS built-in technology. This wireless multi-room audio platform allows the receivers to communicate with other Denon and Marantz products throughout the home. A notable upcoming feature, announced during the Kawasaki preview, is a firmware update that will allow Denon Home wireless speakers to be used as surround channels. This effectively eliminates the need to run long speaker wires across a living room, solving a common pain point for home cinema enthusiasts.
The HEOS app serves as the primary interface for streaming, allowing users to control playback in multiple zones from a smartphone or tablet. The receivers also support AirPlay 2 and Bluetooth (both in and out), enabling users to listen to their TV audio through wireless headphones for private late-night viewing.
