Denon AVC-X6800H

The AVC-X6800H is crammed full of features, as are the step-down AVR-X2800H and AVC-X3800H amplifiers in the current range. Denon claims that this amp can deliver 140W per channel at 8 ohms, or 175W at 6 ohms with two channels driven – the same figures given for the previous generation model. We have no exact figure for power output with all channels driven, but Denon says that all amps in its current range should deliver 70 per cent of the claimed two-channel related power output when running five channels.

The AVC-X6800H features support for 11.4 channels, with preamplifier processing up to 13.4 channels. This means you can use this amplifier with a full 7.4.4 Dolby Atmos surround sound speaker system without the need for an external power amplifier.

Denon has also upgraded connectivity with this new model, making it a better choice for gamers over the AVC-X6700H. You will now find seven full-bandwidth HDMI 2.1 inputs on the rear of the unit (up from just one on the previous model), with three HDMI outputs – one main-zone eARC connector and two additional zones to power speakers in other rooms if you wish to repurpose the assignable surround back and height channels. You’ll also find phono, dual coaxial and dual optical inputs too, as well as a wired network connection and two terminals to screw on the Bluetooth and wi-fi antennae – which takes us nicely onto wireless connectivity.

HEOS (Denon’s in-house developed wireless multi-room system) is, of course, included here, accompanied by a handy app to set up the system and play music. Denon is touting an upgraded HEOS AIOS 6.5 module, although it’s not entirely clear what that upgrade entails. You’ll also find Spotify Connect and Amazon Music HD connectivity support on the AVC-X6800H, which makes streaming music from either service an absolute breeze. Tidal is also supported via the HEOS app as a connected music service for those wanting to tap into high-resolution music streaming. While it’s not included yet, the AVC-X6800H is also expected to receive Roon Ready certification in an upcoming update.
