Price and rating as shown on Amazon when we collected them. Both change.
The Denon AVR-X1800H sits in the middle of the three Denon receivers in this guide: £529.00, against £877.72 for the AVR-S970H and £449 for the AVR-S770H. It claims more power than either of them. The bullet points promise "up to 145W per channel", and the spec table underneath repeats it three times — Output Power 145 Watts, Wattage 145 watts, Output Wattage 145 Watts. That is the opposite of what happens elsewhere in this guide, where the box number and the small print disagree by 110 W or 65 W. The HDMI count holds too: the bullets say 8K runs on "three of six HDMI inputs and one output", and the spec table's Total HDMI Port reads 6.
One number on this page still does not close. The listing shows 4.3 out of 5 from 47 ratings, while the star breakdown given with it adds up to 100 — 9 one-star, 1 two-star, 5 three-star, 19 four-star and 66 five-star. Two counts, one page, and they do not match. What you get for the money is set out in the same listing: 7.2 channels, Dolby Atmos and DTS:X, Audyssey room correction, AirPlay 2 and HEOS Built-in. Every figure here comes from the Amazon listing — we have not tested this receiver ourselves.

Questions people ask
Does the Denon AVR-X1800H really deliver 145 watts per channel?
The bullet points say "up to 145W per channel" and the spec table lists Output Power, Wattage and Output Wattage as 145 Watts, so the two agree. The listing does not state the impedance or how many channels are driven for that figure.
How many HDMI inputs does it have?
Six, according to the spec table's Total HDMI Port. The bullets add that 8K is supported on three of those six inputs and one output.
Is it better value than the other Denon receivers in this guide?
At £529.00 it costs less than the £877.72 AVR-S970H yet claims 145 W, where that model's own spec table states 75 W. The £449 AVR-S770H is cheaper still and states 140 W.
What room correction does the Denon use?
Audyssey. The bullets mention "Audyssey EQ software" for calibrating sound to the room, and the special features field lists "Audyssey Room Correction".
What can I stream to it?
The listing gives Wi-Fi and Bluetooth, AirPlay 2 for Apple Music, and HEOS Built-in for wireless streaming to compatible HEOS components, controlled with the HEOS app.
Do the ratings on the listing agree with each other?
No. The score shown is 4.3 out of 5 from 47 ratings, but the star breakdown supplied with the page totals 100 (9+1+5+19+66), so the two figures do not match.
