Denon
AVC-X4800H
"Denon's flagship X-series — the AVR I'd specify for a serious 11-channel Atmos build before stepping up to separates."

The review
The AVC-X4800H sits at the top of Denon's mainstream X-series and is the unit you specify when the X3800H stops being enough. 11.4 channels of processing, 9.4 channels of amplification with Denon's monobloc-style topology, and 13.4 pre-outs for the day you decide the AVR's amp section isn't keeping up.
Power: 140W per channel into 8Ω with two channels driven, 4Ω-stable across the channel array. Real-world this drives serious main speakers without breaking a sweat — KEF R7 Meta, Klipsch RP-8000F II, even the more demanding KEF R3 Meta in the standmount slot. The monobloc-style amp design means each channel runs from its own power-supply rail, which matters when a 9.4.6 Atmos array hits a peak that lights up every channel simultaneously.
Tonally Denon are more neutral than Marantz — closer to flat through the front mains, with slightly more bass impact than the Cinema 30 at the same tier. For movie-first systems with serious sub integration, the X4800H pairs more naturally. For 70/30 music/film, the Cinema 30's HDAM analogue stage still wins on warmth.
Dirac Live is included; Audyssey XT32 is the fallback. AKM premium DACs (the same family used in Denon's separates) handle the analogue conversion. HDMI 2.1 throughout — 8K passthrough, VRR, ALLM, all eight inputs.
The 11-channel AVR to buy when you want flagship-class capability in a single box.
