Denon AVR‑X1800H
no budget ceiling
Wirecutter's pick for most people and the safest all-rounder across 12 sources — 7.2 channels, 5.1.2 Atmos and Audyssey MultEQ XT for $849.
Fit ledger — need → measured evidence
■ The catch — co-equal billing, always
It stops at 5.1.2 Atmos. Seven amplified channels means two height speakers, full stop — there is no path to a four-ceiling-speaker 5.1.4 layout. And it has one HDMI output, so a TV and a projector cannot both stay plugged in. Getting to 5.1.4 means nine amplified channels and roughly $1,799.

Traps — this verdict avoids
Why the Denon AVR-X1800H is right for you
It avoids every trap below — and for anyone, no budget cap, it is the pick because it delivers:
Phantom HDMI 2.1 ports
"Six HDMI 2.1 inputs" rarely means six fast ones — on most receivers only 2-3 inputs carry the full 40Gbps; the rest run at 24Gbps, which is fine for 4K/60Hz and not enough for 4K/120Hz gaming. We check which port count is real.
Channel-count math
A 7.2-channel receiver tops out at 5.1.2 Atmos — two height speakers. Four ceiling speakers (5.1.4) need nine amplified channels, which starts around $1,799. Buying 7.2 and planning a 5.1.4 ceiling is the most common expensive mistake here.
Wattage theatre
Quoted watts are measured with only two channels driven into 6 ohms — all-channels-driven output is 30-50% lower, and the numbers are not comparable across brands. Rooms under 3,000 cubic feet are fine on 80-100W/ch; bigger rooms want 120W+.
