Denon's 11.4-channel flagship pushes 8K HDMI 2.1 across all seven inputs and two of its three outputs, with the third output dedicated to Zone 2 in 4K. The X6800H processes 13.4 channels internally, with eleven on board amplifiers and full 13-channel pre-outs for external amplification — plus four independent subwoofer pre-outs for optimised bass distribution. Audyssey MultEQ XT32 ships standard and Dirac Live is available as a paid upgrade. HDMI eARC sits on Main Out 1, and a moving-magnet phono input lets you hook up a turntable directly without an outboard pre-amp.
Denon’s 11.4-channel 8K flagship: 7 HDMI 2.1 inputs (all 8K/40Gbps), 3 HDMI outputs, 13-channel pre-outs and 4 subwoofer pre-outs.
