The one box everything plugs into
A receiver is a switch, a decoder and an amplifier in one chassis, and the specification that misleads most is the power figure. Read the conditions: a maker stating "100 W into 8 ohms, 20 Hz–20 kHz, two channels driven, 0.08% THD" has measured something, while "1,000 W" with no conditions is a sum of peaks across every channel. The second thing to check is the HDMI board, because it dates the machine faster than the amplifier does — 4K at 120 Hz, VRR and ALLM matter for a console, and 8K passthrough mostly does not. Third is room correction, which is the feature that changes the sound of a real living room more than any other, and whose versions differ far more than the marketing names suggest. We compare channel count, stated power with its measurement conditions, HDMI version and features, room correction system, and streaming and multiroom support.
In brief
We compare four AV receivers on what each listing publishes. Two had an Amazon.com offer on October 25, 2026, from $150 to $849. On this shelf HDMI decides whether a box is a receiver at all, the channel count decides whether height speakers are possible, and the US version decides what you actually buy. The Denon AVR-X1800H is the complete system here; the Donner is an amplifier for TV sound and a microphone.
5.1 channels · Bluetooth 5.3 · optical and coaxial in · USB · FM · 2 microphone inputs · echo · RCA
A 5.1 amplifier with two microphone inputs and echo — which places it between a home theater receiver and a karaoke amplifier, and the page says which parts serve which.
Best for: A room that wants five speakers driven cheaply from an optical output, and where karaoke is a real use rather than a joke.
≈ $150
7.2 channels · Dolby Atmos · DAB tuner · HDMI
A 7.2 receiver from the house that states power with its conditions — the specification style that makes a receiver comparable to anything else that does the same.
Best for: A first proper surround system, with enough channels to add height speakers later without replacing the receiver.
≈ $849
5.2 channels · 8K HDMI · Bluetooth · DAB tuner
A 5.2 receiver with an 8K-capable HDMI board — the board is what dates a receiver, and this one is specified for a resolution beyond what most systems will use.
Best for: A first 5.1 system where the budget matters and the HDMI board should not be the reason to replace it in three years.

7.2 channels · Dolby Atmos Height Virtualizer · gaming features · voice control · network receiver
A 7.2 network receiver with a height virtualizer — processing that produces height without ceiling speakers, and which the maker names rather than implies.
Best for: A room where ceiling speakers are impossible and a console is part of the system.

Seven amplified speaker channels and two subwoofer outputs. Seven channels cover a 7.1 layout, or a 5.1.2 Dolby Atmos layout with two height speakers; the second subwoofer output lets two subwoofers smooth the bass across a room. A 5.1 or 5.2 receiver has no channel left for height.
It is a 5.1 amplifier with a long input list — Bluetooth, optical, coaxial, USB, FM and two microphones with echo — but its listing states no HDMI. Without HDMI it cannot take Dolby Atmos or lossless sound from the television, and it cannot switch video sources, which are the two jobs that define an AV receiver.
No. DAB and DAB+ are European broadcast systems, and there is nothing to receive here. The Denon reviewed on this site is the European AVR-X1800HDAB; the North American version, the AVR-X1800H, is the same receiver without that tuner, and it is the one sold on Amazon.com.
A microphone measures each speaker from the listening position and the receiver adjusts levels, distances and equalization to the room. The Denon's range includes it, though this listing does not name the version; the Onkyo's listing does not state it at all.
Rarely for 8K itself. An 8K-capable board is usually what carries 4K at 120 Hz and variable refresh rate from a game console, and the HDMI board dates a receiver faster than its amplifier. The Onkyo states 8K capability; check the exact HDMI features on any listing before buying for a console.
Only if the television sends it. Atmos from a built-in streaming app travels back from the TV to the receiver over HDMI eARC, or as Dolby Digital Plus over ARC; it does not travel over optical. Check that the television's HDMI port is labeled eARC or ARC, and turn on passthrough in its audio menu.
On this shelf HDMI decides whether a box is a receiver at all, the channel count decides whether height speakers are possible, and the US version decides what you actually buy. The Denon AVR-X1800H is the complete system here; the Donner is an amplifier for TV sound and a microphone.
