Denon X1800H vs S970H
Entry X-line vs top S-line — which should you buy?
The short answer
The tier badges don't decide this one: like-for-like, the Denon AVR-S970H rates 10W higher than the X1800H with the same MultEQ XT correction and the same stated impedance rating, and it's the side with a stated HDMI 2.1 port count and a second output. Buy whichever is cheaper on the day — the sheets give the S970H the small edge.
As tracked by Home Theater Builder: the Denon AVR-X1800H tracks at $849; the Denon AVR-S970H at $799. How we verify this data → The crossover point of Denon's two ranges: the cheapest X and the dearest S. The tier badges say X wins; the normalized power fields say otherwise.

Reading the numbers honestly
This is a like-for-like comparison — 80W (X1800H) vs 90W (S970H), both at 8Ω, two channels driven, 0.08% THD — and it's the S-line unit that rates HIGHER, by about 0.5 dB. Both carry Audyssey MultEQ XT, both are 7.2 designs with two sub pre-outs, and both state a 4–16Ω impedance rating. The S970H also states a second HDMI output and four full-bandwidth HDMI 2.1 ports in our data.
Compatibility · computed, not written
Checked against a bookshelf that dips to a stated 3.5Ω like the KEF LS50 Meta: KEF LS50 Meta
Can the Denon AVR-X1800H drive the KEF LS50 Meta?
Denon AVR-X1800H states a 4Ω-minimum rating; the KEF LS50 Meta dips to a stated 3.5Ω 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.

Can the Denon AVR-X1800H and Denon AVR-S970H pass 4K/120 through?
The Denon AVR-X1800H states 40 Gbps HDMI bandwidth — enough for full 4K/120; the Denon AVR-S970H states 40 Gbps HDMI bandwidth — enough for full 4K/120.

Buy whichever is cheaper on the day — the sheets give the S970H the small edge.
Stated amplifier ratingDenon AVR-S970H — 90 vs 80W under the identical 8Ω/2ch/0.08% context — the 'lower-tier' unit rates higher.
Two displays (TV + projector)Denon AVR-S970H — The S970H states 2 HDMI outputs; the X1800H states 1.
Everything else recordedEither — Same 7.2 layout, same MultEQ XT, same stated 4–16Ω rating.
What our normalized data adds
NOT ON THE SPEC SHEETS- The tier ladder inverts on the amp spec: the S-line S970H rates 90W to the X-line X1800H's 80W under the IDENTICAL 8Ω / two-channel / 0.08% THD context.
- Both carry Audyssey MultEQ XT and a stated 4–16Ω impedance rating — the fields that usually separate tiers are equal here.
- The S970H states 2 HDMI outputs and 4 full-bandwidth HDMI 2.1 ports; the X1800H states a single output.
