Denon AVR-S980H Review — More Power, Wireless Surround & the Same Denon DNA

The Denon AVR-S980H sits at the top of Denon’s S-series lineup and makes a compelling case for anyone who’s outgrown a mid-range receiver — or who was eyeing the AVR-S770H and wants to know if spending more is worth it. More power per channel, wireless surround capability, and the same trusted HEOS ecosystem make it a meaningful step up rather than a spec-sheet shuffle.

In this Denon AVR-S980H review, we break down its real-world performance, connectivity, and who it’s actually built for — so you can decide whether it belongs in your setup.

Sound Quality & Performance

The AVR-S980H carries Denon’s signature sonic character — warm, composed, and detailed — but with noticeably more headroom than the S770H thanks to its 90W-per-channel output. That extra power matters most in larger rooms and with speakers that dip into the 4-ohm range, where the S770H could feel constrained at higher volumes.

One number worth understanding before it shapes your expectations: like virtually every AV receiver on the market, that 90W-per-channel figure is a 2-channel-driven rating — measured with only two of the seven channels active, not all of them working simultaneously the way they would during an actual movie scene. Denon’s parent company, Sound United, is on record guaranteeing roughly 70% of that 2-channel figure when multiple channels are driven at once, which is actually more transparent than many competitors. In practice, that means real-world output with all channels active during a busy Atmos mix runs meaningfully below the headline number — still enough power for the room sizes this receiver is built for, but worth knowing so the spec sheet doesn’t set the wrong expectation.

Dolby Atmos performance is strong for this price tier. During height-heavy content — rain and off-screen ambience are a common test case — the overhead channels stay distinctly separated from the main soundstage rather than blurring into general reverb, and the transition as effects pan overhead is smooth rather than abrupt. DTS:X material holds up equally well, with precise low-frequency management that keeps dialogue locked to the center channel while the surround field expands around it.

For stereo music listening, Pure Direct mode strips away video-processing and bass-management circuitry entirely, giving the amplifier section a cleaner signal path than it gets during normal multi-channel playback. Through a well-recorded acoustic or jazz track, that shows up as tighter bass definition and a more distinct sense of instrument placement than you get with Pure Direct switched off — the kind of difference that’s subtle on casual listening but real once you’re paying attention for it.

Wireless Surround — What It Actually Means

This is the feature that most clearly separates the S980H from the S770H, and it deserves a clear explanation rather than a spec-sheet mention. Wireless surround lets you connect compatible Denon or HEOS wireless speakers as your rear surround channels — eliminating the need to run speaker cables across the room. For renters, open-plan spaces, or anyone who’s been putting off a proper surround setup because of cable routing, this is a genuine quality-of-life upgrade.

It works via HEOS — the same multi-room platform used for whole-home streaming — so if you already have HEOS speakers in your home, they can be reassigned as surround channels without additional hardware. The receiver handles latency compensation internally to keep lip-sync aligned between the wired front channels and the wireless rears.

Worth setting realistic expectations: wireless surround is genuinely more setup-dependent than running speaker cable. It leans on your home’s Wi-Fi environment, so a crowded 2.4GHz band or a rear speaker placed too far from the receiver can introduce occasional dropouts that a wired connection simply doesn’t have to contend with. For most home layouts this isn’t an issue in practice, but it’s the tradeoff you’re accepting in exchange for not running cable across the room — not a feature that’s flawless in every environment.

If you’re building a wired surround setup, this feature is irrelevant to you. But if cables have been the barrier between you and a full Atmos rig, the S980H removes that barrier entirely.

Smart Features & Connectivity

The AVR-S980H supports 8K/60Hz and 4K/120Hz pass-through across its HDMI inputs, with HDR10+, Dolby Vision, HLG, and Dynamic HDR all supported. Gamers get VRR, ALLM, and QFT for smooth, low-latency performance on PlayStation 5 and Xbox Series X — the same gaming feature set as the S770H, unchanged.

Streaming is handled through HEOS Built-in, with support for Spotify, Tidal, Amazon Music HD, and more. Dual-band Wi-Fi, Bluetooth, and AirPlay 2 cover every wireless scenario, and two-zone audio support lets you run a separate source in a second room while the main zone plays independently. Voice control via Alexa, Google Assistant, or Siri rounds out a connectivity package that leaves very little off the table at this price point.

Room calibration uses Audyssey MultEQ XT — a step up from the standard MultEQ in the S770H — which provides more precise frequency correction across a wider range. For first-time surround setup owners, this makes the initial configuration noticeably more accurate without requiring manual speaker adjustment.

Rear Panel & Setup

The rear panel is well-organized for a receiver in this class. Six HDMI inputs and two outputs give you enough ports for a typical living-room setup without needing a separate HDMI switcher. Speaker terminals are solid and accept both bare wire and banana plugs cleanly. A dedicated phono (MM) input means turntable owners don’t need an external preamp — a thoughtful inclusion that the S670H also carries.

Setup follows Denon’s guided on-screen assistant, which walks through speaker configuration, distance calibration, and Audyssey room correction in a logical sequence. First-time AVR owners will find the process straightforward; experienced users can skip straight to manual configuration if preferred.

S980H vs S770H — Is the Upgrade Worth It?

If you’re wondering whether the S980H justifies the price difference over its sibling, here’s the honest breakdown:

The upgrade makes clear sense if: you have a larger room that 75W struggles to fill, you want wireless rear surrounds, or you need two HDMI outputs (for a projector and a TV simultaneously). If none of those apply to your setup, the S770H covers the same ground for less — check current availability and pricing on Amazon before deciding.

Final Verdict

The Denon AVR-S980H is the strongest receiver Denon currently offers in the S-series, and it earns that position through meaningful upgrades rather than incremental spec bumps. The extra power, wireless surround capability, upgraded room correction, and dual HDMI output combine into a receiver that genuinely serves a wider range of rooms and setups than the S770H could.

For anyone building or upgrading a medium-to-large home theater, it’s a confident recommendation. If your room is small and your speaker setup is straightforward, the step-up cost may outpace what you’ll actually hear — in which case, check our Denon AVR-S670H review for a leaner entry point into the same ecosystem.
