Price, Value, and Where It Sits in Denon’s Current Range

Street pricing and real-world dealer offers shape the true value more than MSRP does. The listed MSRP is $3,500, while some US retailers show near-$3,799 listings. Most buyers should shop the street price rather than rely on launch MSRP.

What you pay for at this tier

The premium covers high channel count, seven full-bandwidth HDMI 2.1 inputs, and flexible pre-outs for future amplifiers. You also get advanced processing and multiple outputs for complex speaker setups.

Head-to-head value: model vs Arcam AVR5

Arcam’s AVR5 retails near $2,000 but needs an Arcam PA410 (~$1,650) to match channel power. That brings total ownership close to $3,650 — roughly the same range as this model.

Item	Typical US Price	Notes
MSRP	$3,500	Launch guidance only; shops may vary
Common retail listing	$3,799	Street price can exceed MSRP at some dealers
Arcam AVR5 + PA410	$3,650 (approx.)	Matches amplification but different sound character

Upgrade and budgeting notes

If you own the prior model, upgrades are most compelling for expanded HDMI 2.1 and newer processing. For systems needing more than 11 amplified channels, include external amplifier costs in your budget.

Build Quality, Design, and Day-to-Day Usability

Physical build and everyday controls define how easy this unit is to live with. The faceplate follows the familiar dual-knob layout with a clear central display. That design gives quick visual feedback about source and volume during normal use.

Chassis, weight, and front panel ergonomics

The chassis weighs 15.6 kg, which matters for rack placement and ventilation. Plan for extra space if you rack-mount it or tuck it into enclosed furniture.

The source and volume knobs are easy to grip, and the display is readable from seating position. That helps when you change input or check mode at a glance.

Front flap convenience

The front flap hides useful quick-access features. You get a dedicated setup microphone jack for calibration runs, a USB port, and a headphone output for private listening.

These ports speed troubleshooting and temporary listening without digging to the rear inputs or outputs.

Remote, app, and menu usability

The supplied remote handles core tasks reliably but lacks backlighting and some single-press shortcuts. Expect to use the on-screen menu for a few advanced functions.

HEOS app control reduces friction, especially when the receiver sits in a cabinet. The app makes input switching and basic streaming faster than the hand remote.

The on-screen setup guidance is clear and step-by-step. It flags wiring or speaker position issues, which shortens setup time and improves final sound by ensuring levels and bass management are correct.

Item	What to expect	Impact on use
Weight	15.6 kg	Easier DIY installation; plan ventilation
Front flap	Microphone, USB, headphone	Quick calibration and private listening
Control options	IR remote + HEOS app	Remote covers basics; app aids daily control
On-screen setup	Step-by-step guidance	Reduces setup errors; improves sound

Features and Connectivity That Define the Experience

Connectivity here is about real-world convenience: multiple 2.1 HDMI ports, flexible outputs, and modern streaming options that fit typical living rooms.

HDMI routing and video support

The unit provides seven hdmi inputs and three HDMI outputs with eARC. It handles 8K/60 and 4K/120, plus VRR, ALLM, QMS and QFT to keep consoles responsive.

Wide HDR and video formats

Movie collectors get broad coverage: Dolby Vision, HDR10+, HLG, HDR10 and IMAX Enhanced playback. That reduces format anxiety across players and streaming apps.

Immersive audio, channels, and bass

Supported formats include Dolby Atmos, DTS:X and Auro-3D, plus upmixers to expand legacy mixes. Internally it delivers 11 channels of amplification and up to 13.4 preamp processing with external amplifiers.

Subwoofers, legacy I/O, and streaming

Four subwoofer outputs allow smoother bass across the seating area and one output can drive a tactile transducer for seat-shake effects. Legacy inputs include phono, optical/coax, multi-zone I/O, triggers and RS-232C.

Streaming and control: HEOS, AirPlay 2, Spotify Connect, Tidal, Bluetooth and voice assistants give flexible multi-room playback and simple hands-free control.

Feature	Why it matters	Real use
Seven HDMI	Keep all sources connected	Multiple consoles, Blu-rays, streamers
Three outputs + eARC	Main display + zones, TV app audio return	Watch in living room; send audio to second display
Four subs	Even bass, tactile option	Smooth low end for seats and HT furniture

Setup and Room Calibration in Real Rooms

Begin with a single-seat check: confirm HDMI inputs, speaker polarity, and display sync before moving to calibration.

Audyssey workflow and microphone placement

Use the included microphone and the front jack to run Audyssey. Place the mic at the main seat, then follow the on-screen prompts for multi-point measurements.

Audyssey typically guides you through several positions to map room effects. Small mic shifts change dialogue clarity and bass smoothness, so be methodical.

Dirac Live and Bass Control notes

Dirac Live is supported but not bundled. Plan to buy a license, a recommended measurement microphone, and a laptop to run the process.

Dirac Live Bass Control improves multi-sub integration and bass articulation in difficult rooms.

Speakers, channels and multi-zone choices

The internal amps cover a 7.4.4 layout with sensible channel assignments. Adding more processing or powering extra speakers needs external amplification.

Assigning channels to Zone 2/3 trades off main-room power. Choose based on how often you use multi-room audio.

Step	What to check	Why it matters
First-day check	HDMI, polarity, display sync	Prevents errors before calibration
Audyssey run	Microphone multi-point measurements	Corrects room tonal balance
Dirac option	License + mic + PC	Better sub integration and room correction

Sound Performance for Movies, Gaming, and Music

Across films, games, and albums the presentation blends musicality with precise imaging. The overall sound tilts warm and rich while keeping high-frequency clarity that helps vocals and effects cut through.

Signature, clarity and dynamics

The sound signature favors a lush midrange with tight lows and clean treble. Dynamics and scale feel strong at moderate volume, giving action scenes real punch without sounding aggressive.

Dialogue and vocal detail

Dialogue stays intelligible in crowded scenes thanks to a well-defined center channel. Clear vocal rendering matters more than raw power for readability in mixes with heavy background effects.

Surround imaging and height effects

Surround steering is smooth; effects pan across the room without gaps. Height channels deliver convincing overhead motion in Dolby Atmos mixes, enhancing placement accuracy and immersion.

Bass authority and integration

Bass has two faces: fast, articulated lows for music and strong impact for films. Multi-sub setups and proper calibration—Audyssey baseline or paid Dirac upgrades—make the biggest difference for tight, coherent low end.

Music, streaming and playback modes

Streaming via Spotify Connect, HEOS and Tidal sounds crisp with good dynamics. Use Direct mode for unprocessed music; switch processing on to unify mixed speakers or room imbalances.

All-channel stereo

All-channel stereo delivers bold, room-filling sound for parties. Critical listeners may notice slightly softened attack and less pinpoint imaging versus stereo or Direct modes.

How It Compares to Key Alternatives

When choosing between top-tier receivers, the right trade-offs hinge on real-world needs more than spec sheets.

Upgrade decision: when swapping from the prior model makes sense

If you own the previous model, upgrade urgency is low unless three things matter to you: multiple full-bandwidth HDMI 2.1 gaming sources, the latest processing platform, or the revised internal design.

Real-world upgrade means audible improvements at normal listening levels — clearer dialogue, tighter transient punch, and smoother surround cohesion rather than just higher numbers on a spec sheet.

Feature and sonic contrasts with Pioneer and Arcam class rivals

Pioneer VSA-LX805 matches many features: formats, room correction options, and multi-zone outputs. That makes it a strong feature-parity contender.

By contrast, the Arcam AVR5 tends to sound more agile and natural to some listeners. However, Arcam may need external amplifiers to match channel power, which raises total system cost.

Compare	Feature parity	Sonic character
This model	Formats, processing, multi-zone	Warm, wide-scale sound with solid punch
Pioneer VSA-LX805	Very similar feature set	Balanced, detailed presentation
Arcam AVR5 (+ amp)	Needs added amplifiers to match channels	Agile, more neutral timbre

Amplification, connectivity, and ecosystem

Consider amplification strategy: a rival’s lower entry price can become less compelling after adding external amplifiers to reach comparable channel counts.

Connectivity wins for households with many consoles — seven full-bandwidth HDMI inputs remove the need to swap sources or add external switchers.

Finally, ecosystem and control matter. Menus, app maturity, and setup guidance affect the daily experience more than raw specs for many buyers.

• Choose this model if: you need many HDMI 2.1 sources, built-in 11-channel power, and easy setup.
• Choose a rival if: you prioritize a more neutral, music-first sonic signature or lower upfront cost and plan to add amps later.

Conclusion

If you want a single hub that handles gaming, movies, and multi-channel music, this is a strong contender for a modern home setup.

Strengths: broad HDMI support for multiple inputs and reliable video handling, immersive Dolby Atmos staging, and wide dynamic performance that keeps music and film moments engaging.

Important caveat: it processes up to 13.4 channels but only powers 11 internally, so high-channel speaker arrays will need an external amplifier to reach full capability.

Calibration: Audyssey gives solid baseline tuning for most rooms. Dirac Live (paid) and Bass Control are the upgrade path for tighter bass and finer tonal balance.

Bottom line: excellent daily performance, clear dialogue, and flexible expansion make it a strong long-term home theater hub.
