Denon is refreshing the middle of its AV receiver lineup, swapping the AVR-X2800H and AVR-X3800H for the new AVR-X2900H and AVC-X3900H. From the outside, the family resemblance is unmistakable — but the meaningful changes live exactly where they should for a home theater: in the audio path and in how flexibly you can build a system around it.
The headline engineering upgrade is the move to a 32-bit DAC system. This isn’t a firmware tweak dressed up as progress — it’s a change to the hardware foundation of digital-to-analog conversion, the very stage that governs detail retrieval and dynamic range. Denon has long obsessed over its converters, and this generation keeps that tradition going.
Where the two models part ways is scalability:
- AVR-X2900H — a 7.2-channel receiver rated at 95 W per channel. Price: €1000.
- AVC-X3900H — a 9.4-channel configuration delivering 105 W per channel. Price: €1499.
The nine-channel architecture of the flagship, paired with support for four subwoofer outputs, opens the door to more ambitious layouts with height channels and a distributed low-frequency section — exactly what enthusiasts want when stacking up multi-layer ceiling configurations.
Both units handle today’s immersive formats, Dolby Atmos and DTS:X. That’s been table stakes in home cinema for years, but running them through a fresh processor and updated converters should yield a tighter, more composed presentation.
On the video side, the receivers are built for current and future sources alike. Each carries six HDMI inputs with support for 4K at 120 Hz and 8K at 60 Hz. That’s enough bandwidth for next-gen game consoles and their high frame rates, with headroom held in reserve for the 8K sources still on the horizon.
One particularly welcome addition is support for wireless rear speakers. For anyone who’d rather not snake cables across a room to the surrounds, this erases one of the most irritating chores of a home theater install — a real boon in living rooms where running wire along floors or walls simply isn’t an option.
Taken together, this is an evolutionary but purposeful update: the new DAC works in service of sound quality, the flagship’s expanded channel count serves system scale, and the wireless rears plus full 8K-ready HDMI serve convenience and the longevity of your investment.
Sales in Japan are slated to begin on June 26, 2026.
