As tracked by Home Theater Builder: the Denon AVR-X1800H states 4 HDMI 2.1 ports; the Denon AVR-S760H states 3.How we verify this data →
The X1800H carries Audyssey MultEQ XT room correction to the S760H's base MultEQ, and the power figures (80W vs 75W, both 8Ω, two channels driven, 0.08% THD) are level. A same-brand ladder question. Either way, the spec differences are smaller than the tier names imply.

Reading the numbers honestly
This is the rare comparison where the power figures ARE like-for-like: 80W (X1800H) vs 75W (S760H), both measured at 8Ω, two channels driven, 0.08% THD — a difference you will never hear. The honest differences live elsewhere: the S760H explicitly states a 4–16Ω speaker-impedance rating where the X1800H publishes none, and the X1800H states 9 processing channels and Audyssey MultEQ XT where the S760H is a 7.2 design with base MultEQ.
Compatibility · computed, not written
Checked against a bookshelf that dips to a stated 3.7Ω like the KEF Q150: KEF Q150
Can the Denon AVR-X1800H drive the KEF Q150?
Denon AVR-X1800H states a 4Ω-minimum rating; the KEF Q150 dips to a stated 3.7Ω minimum, a little below that floor. Most receivers handle a marginal dip at normal volumes — it's worth watching only at very high output on an entry-level unit.

Computed from the catalog's normalized fields — the same fields the builder's compatibility engine reads. A missing field reads as "can't check", never as a pass.
Gaming & connectivity · answered from the spec sheets
How many HDMI 2.1 ports do the Denon AVR-X1800H and Denon AVR-S760H have?
Denon AVR-X1800H states 4 full-bandwidth HDMI 2.1 ports; Denon AVR-S760H states 3. Full-bandwidth ports are the ones that carry 4K/120 and VRR — the count that matters for wiring multiple current-gen consoles.
Can the Denon AVR-X1800H and Denon AVR-S760H pass 4K/120 through?
The Denon AVR-X1800H states 40 Gbps HDMI bandwidth — enough for full 4K/120; the Denon AVR-S760H states 40 Gbps HDMI bandwidth — enough for full 4K/120.
The verdict
Buy the Denon AVR-X1800H — the higher-tier receiver brings 9 stated processing channels (unstated for the S760H) and the better room correction.
A genuinely like-for-like power comparison: 80W vs 75W, both at 8Ω / two channels driven / 0.08% THD — we can say so because the measurement context is stored with the value.
The S760H states a 4–16Ω impedance rating; the X1800H publishes NO impedance range in our data — the lower-tier unit is the one with the 4Ω-friendly paper trail.
The tier ladder's price order is a tracked figure, not a tier promise.
HDMI 2.1 is level once counted the same way: three HDMI 2.1 inputs and one HDMI output on each (our X1800H row's "4 ports" counts the output too); processing channels: 9 stated vs unstated.
