Denon has unveiled the world’s first 8k-ready AV receiver line-up. Significantly, the latest additions to its X-Series, the Denon AVC-X6700H, AVC-X4700H, AVC-X3700H, and AVR-X2700H also support 4k/120kHz gaming with VRR, QFT, QMS and ALLM, for next generation gaming. For many enthusiasts, the latter will be the real carrot to upgrade their AV systems.

4k at 120fps looks to be a standard output resolution and frame rate for the upcoming PlayStation 5 and Xbox Series X games consoles.

Variable Refresh Rate (VRR) reduces frame tearing, while Auto Low Latency Mode (ALLM) and Quick Frame Transport (QFT) reduce input lag and improve stats.

Our understanding is that a single dedicated 8k HDMI input enables 8k/60Hz and 4k/120Hz video pass-through. This could prove an issue for serious gamers planning to buy both of the new consoles. The solution would be to connect the second console direct to your 8k and 4k 120fps display, and route audio back  to the AVR using HDMI.

There’s also new HDMI feature called Quick Media Switching (QMS), which allows a source to instantly switch the resolution or frame rate to eliminate screen blackout.

The new Denon X-Series will also upscale existing HD and 4K content to 8k resolution. As standard, the AVRs support HDR10, HLG (Hybrid Log-Gamma) and Dolby Vision, as well as 4:4:4 Pure Color subsampling and BT.2020 pass-through.

Other niceties include Dolby Vision and HDR10+, and eARC (enhanced Audio Return Channel).

Sonically, the new line-up also push the envelope. The AVC-X6700H and AVC-X4700H also introduce support for DTS:X Pro, which allows installs of up to 13 channels of DTS:X decoding, with speaker configurations such as 7.2.6 or 9.2.4. Denon says IMAX Enhanced films can be heard in 7.2.6 or 9.2.4 speaker configurations courtesy of newly adopted 13.2 channel processing capabilities, with external amplification. The DTS:X Pro feature will be delivered via firmware later this year.

Other 3D sound formats available out of the box include Dolby Atmos, Dolby Atmos Height Virtualization Technology, DTS:X, DTS Virtual:X, IMAX Enhanced and Auro-3D out-of-box.

The AVC-X6700H supports 11 channels of amplification with 13.2 channel processing, the AVC-X4700H and the AVC-X3700H support up to 9 channels of amplification and 11.2 channel processing. The AVR-X2700H is a 7-channel design.

Auro-3D engine is supported by the AVC-X6700H and the AVC-X4700H. IMAX Enhanced decoding is supported by both receivers as well as the AVC-X3700H.

Denon now also supports a new pre-amplifier mode for the AVC-X3700H, AVC-X4700H and AVC-X6700H, previously only found on Denon’s flagship AVC-X8500H. Pre-Amplifier mode provides a clear signal path and more tolerance in clipping levels by disconnecting internal amplifiers when the receiver is used as an AV processor and all speakers are powered by external amplifiers.

Also new this year is a Dual Speaker Setup preset function, which allows users to store and instantly switch between two Speaker configurations. So it’s possible to store both the Audyssey calibration result straight from the receiver and a customized MultEQ curve or frequency range made through the Audyssey MultEQ editor app. Users can also perform Audyssey measurements for two different speaker settings, including 2.0 for music listening and 5.1.4 for surround.

The AVRs are Roon Tested certified and have Heos built-in, for multiroom use and music streaming, alongside Apple AirPlay 2 and Bluetooth. Apple Music streaming is supported through AirPlay 2. The models work with Amazon Alexa, Google Assistant, and Apple Siri.

The AVR-X2700H is priced at £599, with the AVC-X3700H £999 (due August), the AVC-X4700H £1,399 and the AVC-X6700H £2,299 ( both out in July).
