Denon A-Series A/V Receiver Buying Guide: Which Flagship AVR Is Right for You in 2025?

Denon has been building audio gear for more than 115 years, outlasting more mergers and acquisitions than most Fortune 500 companies combined. It joined forces with Marantz in 2002, got swept into DEI Holdings, rolled under Sound United, and now lives inside Harman (itself owned by Samsung). Through all that corporate musical chairs, Denon never lost the plot—it still makes some of the most reliable, feature-packed A/V receivers you can buy.

For decades, Denon has played the workhorse to Marantz’s self-styled “audiophile-approved” sibling. Marantz leans on refinement; Denon leans on power, versatility, and the kind of reliability that keeps a home theater running for years without fuss.

But let’s be real: full-blown A/V receivers face real headwinds right now. The market’s been swallowed by soundbars, and unless you’re willing to drop serious money, very few alternatives can convincingly outmuscle them. A properly set up 5.1 or Atmos rig with height channels and dedicated surrounds will still destroy even the priciest soundbar in terms of immersion—but that requires both space and commitment.

Denon’s lineup hits three price tiers. The entry-level S-Series caters to the budget crowd, the X-Series is the sweet spot for performance per dollar, and the flagship A-Series is where Denon throws everything it has at the wall. Today, we’re narrowing in on the A-Series—the two heavy hitters at the top of the food chain—to figure out which one, if either, deserves a spot in your theater.

What Is an A/V Receiver (AVR)?

An AVR (Audio/Video Receiver) combines three critical functions in one box: a preamplifier, a surround sound processor, and amplification, making it the central hub of any home theater setup. All you need to do is add speakers, source components, and a display—like a TV or projector. In addition, AVRs also include a radio tuner (AM/FM or sometimes just FM), which is what generally sets a receiver apart from a standard integrated amplifier.

Denon AVR-A Series Receivers: 2025 Lineup

Denon’s flagship AVR-A Series currently includes two models aimed squarely at serious home theater enthusiasts:

• AVR-A1H ($7,199): Denon’s most powerful and feature-rich receiver, packing 15 channels of amplification and support for up to 17 channels of audio processing with the help of external amps.
• AVR-A10H ($5,199): A step below the A1H in raw muscle, but still loaded with more than enough performance and flexibility to anchor almost any high-end theater system.

Denon AVR-A Series Preamp Mode

The preamp stage is the command center of any AVR. Every source—Blu-ray player, game console, streamer, media box, or cable/satellite—runs through it. The AVR lets you switch between them without juggling connections, while the preamp handles level matching, volume control, and routing the audio to the amp and the video to your display.

Denon’s A-Series receivers go beyond just physical inputs. Both models include built-in Wi-Fi and Bluetooth for wireless playback, HEOS integration for whole-home audio, and yes, even a good old-fashioned AM/FM tuner for anyone still spinning the dial.

Crucially, both units also feature full multi-channel preamp outputs. That gives you the option to run external amps for more headroom, expand channel count for massive Atmos rigs, or feed audio into a second zone elsewhere in the house.

Denon AVR-A Series Surround Sound Processing

The Denon AVR-X Series handles all the critical audio decoding and digital-to-analog conversion, ensuring clean, accurate sound no matter which source you’re using. Both AVR-A model supports immersive formats like Dolby Atmos,  DTS:X, AURO-3D, IMAX Enhanced, Sony 360 Reality Audio, along with common digital audio formats including Dolby Digital, DTS Digital Surround, MP3, WAV, and PCM.

On the video side, Denon AVRs can upconvert or downconvert signals to match your TV or projector’s native resolution. In practice, though, most setups benefit from letting the display handle video processing for the cleanest, most accurate image.

Denon AVR-A Series Amplifier Mode

The AVR’s amplifier stage takes the analog signals from your sources and drives them with clean, controlled power to each speaker. This ensures every channel maintains tonal accuracy, dynamic range, and clarity, letting movies, music, and games come alive with true-to-source detail and room-filling presence.

Denon AVR-A Series Receivers: Key Features in Common

Exterior Design: The Denon AVR-A Series receivers have a clean, functional exterior with a rectangular status display and essential physical controls that are accessible via the front panel drop-down door, keeping the front tidy without sacrificing usability.

Amplifier Type: Both AVR-A series models incorporate Class A/B amplification, offering a balance of sound quality and power efficiency suitable for home theater setups of varying sizes.

HDR Support: Both AVR-A models pass through HDR10, HDR10+, Dolby Vision, HLG, and Dynamic HDR, ensuring video sources retain their full dynamic range and color accuracy on compatible displays.

HDMI 2.1: Both receivers include HDMI 2.1 inputs with eARC, supporting 4K/120Hz and 8K/60Hz signals, VRR (Variable Refresh Rate), ALLM (Auto Low Latency Mode), and QFT (Quick Frame Transport), making them ideal for high-performance gaming and next-gen video sources.

Phono Input: Each AVR-A model comes with a dedicated phono input that supports MM (Moving Magnet) cartridges, allowing easy connection of a traditional turntable. Turntables with built-in phono preamps can connect to any available analog input instead.

Hi-Res Audio: The AVR-A Series supports high-resolution audio up to 24-bit/192kHz. Compatible digital formats include MP3, WMA, WAV, MPEG-4/AAC, FLAC, and ALAC, as well as DSD playback at 2.8 and 5.6 MHz.

Compressed Audio Restorer: This feature improves compressed audio files such as MP3, WMA, and AAC by recalculating the frequency range to restore detail and clarity, making digital tracks sound more natural.

HEOS Wireless Streaming: Integrated HEOS allows streaming from multiple music services—including Qobuz—with full multi-room control. HEOS-enabled wireless speakers can complement wired speakers, supporting up to 64 zones. You can play the same track throughout your home or select different music for each zone, creating a flexible, whole-home audio system.

Wireless Music Streaming, Connectivity, and Smart Controls

Wireless Music Streaming: Amazon Music HD, Spotify Connect, Pandora, and more—Roon Tested for seamless integration with high-resolution music libraries.

Wireless Connectivity: Bluetooth, AirPlay 2, and Wi-Fi are standard, with a wired Ethernet option available for maximum stability.

Voice Control: Compatible with Alexa Built-in, Google Assistant, and Siri for hands-free operation.

Audyssey Room Correction Built-in: Options include MultEQ, MultEQ XT32, Dynamic EQ, and Dynamic Volume for precise calibration and consistent performance. In addition, Dirac Live room correction, Dirac Live Bass, and Dirac Live Active Room Treatment can be added (licenses required). Dirac Live provides advanced acoustic optimization, delivering clearer vocals, a wider sweet spot, tighter low-end without boom, and an overall more accurate and immersive listening experience. 

Tip: Audyssey Room Correction still remains an option even if Dirac Live is installed. You just can’t use both systems at the same time.

Onscreen Setup Assistant

The Denon AVR-A Series receivers include a built-in Setup Assistant that makes the initial installation simple and stress-free. When you power on your AVR for the first time (with your TV on and the correct input selected), the guided setup menu appears automatically. If you exit the Setup Assistant (using the BACK button on the remote), you can reopen it anytime from the main menu (GUI).

The Setup Assistant guides you through:

• Language selection
• Speaker setup and connections
• Speaker calibration using Audyssey
• Network connection setup
• ARC/eARC HDMI configuration
• Input assignment and labeling
• Mobile control app download instructions
• This process ensures your Denon AVR-A series receiver is ready to perform at its best—making setup easy, even for first-time home theater owners.

Pro Tip: The A-Series AVRs also provide a custom install mode. This provides compatibility with third-party control systems as well as Control4 SDDP certification. Remote monitoring is also provided, which lets integrators provide off-site client support.
