Denon expands X-Series AVR line - hands-on test

Denon has unveiled two new additions to its acclaimed X-Series AV receiver line-up, targeting enthusiasts and custom installation projects that demand precision, flexibility and outright performance.

The new Denon AVR‑X2900H and Denon AVC‑X3900H build on the company’s long-established formula of high channel support, expansive connectivity and artful acoustic tuning, while introducing updated processing and broader calibration options.

The launch reflects a growing divide in the AV market between convenience-led soundbars and dedicated home theatre systems designed for enthusiasts who still value discrete amplification and carefully matched speaker layouts.

While Denon’s recent AVR-S980H focused on making home theatre more approachable, these latest X-Series models are engineered to offer deeper control over system performance and room integration.

At the heart of both receivers is a revised 32-bit multi-channel DAC architecture paired with updated internal components. As with Denon’s higher-end electronics, both units were developed and voiced at the company’s Shirakawa Audio Works facility in Japan, where tuning combines laboratory measurement with extensive subjective listening.

Inside CI travelled to Shirakawa ahead of the launch to hear the receivers in Denon’s reference listening room, where both models were demonstrated using a full Bowers & Wilkins 801 surround speaker system (unlikely to be duplicated in the real world, but a stunning confirmation that these single box units can drive extremely high-end loudspeakers). The results were deeply impressive.

The AVR-X2900H immediately distinguished itself with composure and scale beyond what its price point might suggest, while the AVC-X3900H delivered a level of control and dynamic expression that bordered on startling. We ran through a selection of movie clips, climaxing with Dune Part One. Dialogue placement was pin-sharp, bass management felt impeccably disciplined, and large-scale cinematic passages carried immense energy without losing finesse. In terms of balancing power against price, these receivers set a new benchmark.

The AVR-X2900H is configured as a seven channel (5.1.2) design delivering 95 watts per channel, aimed at enthusiasts stepping beyond entry-level AV performance. Support for immersive audio formats, modern HDMI gaming features and optional Dirac Live room correction positions it as a substantial upgrade for users building more serious cinema systems.

Audyssey calibration remains included as standard, while HEOS multiroom support allows the receiver to integrate into wider distributed audio environments.

The AVC-X3900H moves considerably further into premium territory. Offering nine (5.1.4) channels of onboard amplification (with 11.4-channel processing for larger theatres) at 105 watts per channel, it’s designed to anchor larger dedicated cinema rooms and professionally installed systems. Four independent subwoofer outputs provide greater scope for bass optimisation, while optional support for Dirac Live Bass Control and Active Room Treatment gives integrators access to more advanced acoustic correction tools.

Denon’s dual-calibration strategy remains one of the more pragmatic approaches in the market. Users can rely on Audyssey for straightforward setup or move towards Dirac Live for more granular system shaping as installations become increasingly complex. That flexibility is likely to appeal to CI pros working across a broad range of room sizes and client expectations.

Connectivity and control have also been expanded. Both receivers support HEOS streaming, Apple AirPlay 2, Bluetooth and services including Spotify, Qobuz and TuneIn Internet Radio. Advanced HDMI diagnostics, IP-based web configuration and broad control integration options further underline the company’s focus on custom installation applications.

Gaming support hasn’t been overlooked either. Expanded HDMI connectivity, 1440p pass-through and AMD FreeSync compatibility aim to ensure the receivers remain viable as gaming displays and source hardware continue to evolve.

Denon is also preparing a future firmware update that will allow compatible Denon Home 200, Denon Home 400 and Denon Home 600 models to operate as wireless rear surrounds, offering a more flexible route to immersive audio in rooms where speaker cabling may be impractical.
The AVR-X2900H is priced at £899, while the AVC-X3900H will retail for £1299. Both models are scheduled to become available globally from May 14 through authorised Denon retailers and the company’s online store.
