At prices this close — $49 apart in the row above — the architecture is the whole argument. Buy the Denon AVR-X3900H if you want the bigger bed: nine amplified and eleven processing channels against seven and eight, four subwoofer pre-outs against two, plus stated Auro-3D and IMAX Enhanced. Buy the Marantz CINEMA 60 if you would rather have the sheet you can check — it states Audyssey MultEQ XT, a 4–16Ω impedance range and HDMI version 2.1, plus a 40 Gbps figure recorded from a retailer listing and a three-2.1-port count that is an inference in our data, an eARC port and 8K/60 passthrough, and our X3900H row records none of those seven. Power is not what separates them: 100W against 105W at 8Ω and 140W against 135W at 6Ω, each with two channels driven at 0.08% THD, which is about 0.2 dB either way.
As tracked by Home Theater Builder: the Marantz CINEMA 60 tracks at $1,800; the Denon AVR-X3900H at $1,849.How we verify this data →
Marantz's CINEMA 60 and Denon's AVR-X3900H track close enough that architecture, not budget, is the argument — $1,800 vs $1,849 in the price row above. One of them is the bigger receiver; the other is the one whose sheet you can check.

Reading the numbers honestly
Power is the easy part and it is a dead heat: 100W against 105W at 8Ω and 140W against 135W at 6Ω, each row storing the same context — two channels driven at 0.08% THD — so about 0.2 dB separates them and the contexts match exactly. Architecture is the real difference: 7.2 with eight processing channels and two subwoofer pre-outs against 9.4 with eleven and four. Then comes the disclosure gap, and it is wide. Our AVR-X3900H row records no room-correction system, no impedance range, no HDMI version, no bandwidth figure, no 2.1-port count, no eARC count and no passthrough resolution — seven blanks, where the CINEMA 60 states Audyssey MultEQ XT, 4–16Ω, HDMI 2.1, 40 Gbps, three 2.1 ports, one eARC port and 8K/60. Every one of those blanks is a silence in our data rather than a stated absence, and the Denon does state that a measurement microphone is included, which makes the missing correction platform look like our gap and not the product's. It runs the other way twice: the Denon states Auro-3D and IMAX Enhanced, and the Marantz row records Auro-3D as a No that carries no source of its own in our data and has no IMAX Enhanced field. Two provenance notes on the Marantz side: its 40 Gbps figure is retailer-sourced and its three-2.1-port count is an inference 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 Marantz CINEMA 60 drive the KEF LS50 Meta?
Marantz CINEMA 60 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.
Can the Denon AVR-X3900H drive the KEF LS50 Meta?
Denon AVR-X3900H publishes no rated impedance range, so the pairing with the KEF LS50 Meta (which dips to a stated 3.5Ω minimum) can't be verified from its spec sheet — we treat that as "can't check", not a pass.
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.
At prices this close — $49 apart in the row above — the architecture is the whole argument. Buy the Denon AVR-X3900H if you want the bigger bed: nine amplified and eleven processing channels against seven and eight, four subwoofer pre-outs against two, plus stated Auro-3D and IMAX Enhanced. Buy the Marantz CINEMA 60 if you would rather have the sheet you can check — it states Audyssey MultEQ XT, a 4–16Ω impedance range and HDMI version 2.1, plus a 40 Gbps figure recorded from a retailer listing and a three-2.1-port count that is an inference in our data, an eARC port and 8K/60 passthrough, and our X3900H row records none of those seven.

Amplifier powerEither — 100W against 105W at 8Ω and 140W against 135W at 6Ω, each row storing two channels driven at 0.08% THD — about 0.2 dB, and the contexts match exactly.
Channels and subwoofer outputsDenon AVR-X3900H — Nine amplified and eleven processing channels with four subwoofer pre-outs, against seven, eight and two — the one architectural difference on the page.
A stated room-correction platformMarantz CINEMA 60 — The CINEMA 60 states Audyssey MultEQ XT; our X3900H row records no room-correction system at all, though it does state that a measurement microphone is included — a silence in our data to confirm, not an absence in the product.
HDMI you can verifyMarantz CINEMA 60 — Version 2.1, a 40 Gbps figure, three 2.1 ports, one eARC port and 8K/60 passthrough on the Marantz row; our X3900H row states none of the five — though the 40 Gbps figure is retailer-sourced and the three-port count an inference in our data, so those two are the ones to confirm before buying.
Low-impedance speakersMarantz CINEMA 60 — A stated 4–16Ω range on the Marantz; our Denon row states no impedance range for a speaker match to check against.
Auro-3D and IMAX EnhancedDenon AVR-X3900H — Both are stated on the Denon row; the Marantz row records Auro-3D as a No that carries no source of its own in our data and carries no IMAX Enhanced field at all.

Power is like-for-like on both figures each row states — 100W against 105W at 8Ω and 140W against 135W at 6Ω, each with two channels driven at 0.08% THD — so roughly 0.2 dB separates them and the badges carry more difference than the amplifiers do.
The architectures do not match: 7.2 with eight processing channels and two subwoofer pre-outs against 9.4 with eleven processing channels and four.
Our AVR-X3900H row records NO room-correction system, no impedance range, no HDMI version, no bandwidth figure, no 2.1-port count, no eARC count and no passthrough resolution — seven blanks that are silences in our data, never stated absences.
It runs the other way twice: the Denon states Auro-3D and IMAX Enhanced as manufacturer figures, while the Marantz row records Auro-3D as a No that carries no source of its own in our data and carries no IMAX Enhanced field.
Provenance honesty on the fuller sheet: the Marantz's 40 Gbps HDMI figure is retailer-sourced and its three-2.1-port count is an inference in our data — the two numbers here we would confirm before buying for a 4K/120 console.
A whole network block sits on one row only: the CINEMA 60 states Wi-Fi, Bluetooth, AirPlay 2, Alexa, IP control, a trigger output and five streaming services, against one streaming service and HEOS on our X3900H row, which carries no other network field, with the two tracking within $49 of each other above.
