Denon and Marantz have both announced their new flagship AV amplifiers, the Denon AVC-X8500HA and Marantz AV8805A.

Both brands are offering owners of the previous-generation models an upgrade programme to bring their AV amps up to the same “A” spec of the new Denon AVC-X8500HA and Marantz AV8805A.

8K HDMI 2.1

The new models now include a dedicated 8K HDMI 2.1 input, enabling 8K/60Hz and 4K/120Hz video pass-through, new HDR format support including HDR10+ and Dynamic HDR, and a new HDMI feature called Quick Media Switching (QMS), which allows a source to instantly switch frame rate to eliminate screen blackout.

Several new features are focused on gamers, including Variable Refresh Rate (VRR) to reduce frame tearing and improve overall precision. Auto Low Latency Mode (ALLM) and Quick Frame Transport (QFT) are each designed to reduce lag.

The Marantz AV8805A and Denon AVC-X8500HA are also capable of upscaling existing HD and 4K content to 8K, improving even the poorest source material. There is continued support for eARC (Enhanced Audio Return Channel), which allows lossless and object-based audio transmission such as DTS:X and Dolby Atmos from TV apps or connected devices using a single HDMI cable.


For advanced multi-channel home cinema audio, the updated flagship components now support DTS:X Pro, allowing up to 13 channels of DTS:X decoding with speaker configurations such as 7.2.6 or 9.2.4.

The latest height virtualization technologies provide immersive audio without height channels, creating virtual height effects in a 7.1, 5.1 or 2.1 speaker arrangement.
