Denon AVR-X3800H vs. Onkyo TX-RZ50 Features Comparison:
Design and Build Quality
The Denon AVR-X3800H sports a sleek and modern design with a matte black finish, blending seamlessly into any entertainment setup. Weighing in at 16.8 lbs., it features a 1-Line FLD front display, providing easy-to-read information about the current input and volume level. Check our full review of the Denon AVR-X3800H.
The Onkyo TX-RZ50, on the other hand, tips the scale at a hefty 30.9 lbs., pointing towards its robust build. It maintains Onkyo’s traditional black, industrial design, exuding an air of reliability.
Our personal preference leans towards Denon’s minimalist aesthetics. However, the Onkyo’s solid build could be a more appealing choice for those favoring substance over style.
Power Output
When it comes to power, the Onkyo TX-RZ50 is clearly the more potent contender. With a power output of 120 W/Ch at 8 ohms and a peak of 250 W/Ch at 6 ohms, it outperforms Denon’s AVR-X3800H, which provides a steady 105 W/Ch at 8 ohms.
In real-life application, the extra power from Onkyo does result in a slightly fuller and richer audio experience, especially at higher volumes. However, the Denon holds its ground, producing a crisp and clear sound that rivals Onkyo’s performance.
Video and Audio Inputs/Outputs
Both receivers excel in their video and audio connectivity options. The Denon AVR-X3800H supports 6 HDMI In/Out and features 4 independent subwoofer outputs, an exciting addition for bass lovers. It supports all the latest HDMI technology, including HDR10+, Dolby Vision™, and 8K video.
Similarly, the Onkyo TX-RZ50 offers Discrete Zone 2 HDMI Switching, allowing for different UHD entertainment options in two different rooms. It also supports up to 8K60 resolution for the main zone.
Although both models excel in this aspect, the Onkyo TX-RZ50’s Discrete Zone 2 HDMI Switching feature provides added versatility.
Multichannel Audio Performance
The Denon AVR-X3800H, boasting 105W per channel, provides an engrossing 3D audio experience with Dolby Atmos, DTS:X, IMAX Enhanced, and Auro 3D, which effectively wraps you up in a blanket of immersive sound. Particularly, during the Avengers Endgame final battle scene, the explosions, dialogues, and the subtle background score were effortlessly distinct and crystal clear. The fact that the Denon AVR-X3800H could offer such an enriching sound landscape with a 5.1.4 setup is commendable.
On the other hand, the Onkyo TX-RZ50, packing a more powerful 120W per channel, certainly didn’t disappoint either. The distinction lies in how Onkyo seems to deliver a slightly more aggressive audio performance. During the same Avengers scene, the impact was more dramatic, with a slightly stronger bass and a broader soundstage. While both models performed admirably, if you lean towards a more energetic audio delivery, Onkyo might be the choice for you.
Video Performance
When it comes to video performance, both Denon and Onkyo have shown impressive capabilities. The Denon AVR-X3800H offers 8K video support on all six HDMI inputs and two out of three outputs. The handling of high dynamic range content is also impeccable, thanks to HLG, HDR, Dolby Vision, HDR10+, and Dynamic HDR pass-through.
The Onkyo TX-RZ50, on the other hand, is designed to provide an ultimate 4K gaming experience with 4K/120 and 8K/60 capabilities. The image processing is top-notch, and fast motion sequences in games and action movies are crisp and razor-sharp. It also supports 8K60 resolution in two different rooms from a single receiver.
Advanced Features
The Denon AVR-X3800H boasts impressive features such as Audyssey MultEQ XT32 room correction technology for optimal sound in any space.
The Onkyo TX-RZ50 isn’t far behind. With its THX Certification and IMAX Enhanced Mode, it promises a refined audio experience that stays true to the original source material. Its compatibility with Sonos and multi-zone streaming features show a clear focus on user-friendly smart home integration.
Streaming and Smart Home Capabilities
Both AV receivers shine in their streaming capabilities. The Denon AVR-X3800H uses HEOS® built-in technology, allowing access to various streaming services and sharing with HEOS-enabled speakers in other rooms.
The Onkyo TX-RZ50 stands out with its integrated multi-zone streaming and voice control, compatible with Apple Airplay, Alexa, Google apps, and more. It also offers a range of built-in streaming services and bidirectional Bluetooth wireless technology for versatile connectivity options.
Room Correction Capabilities
The Denon AVR-X3800H utilizes Audyssey MultEQ XT32 room correction technology to optimize the sound, ensuring an optimal listening experience for your room. In contrast, the Onkyo TX-RZ50 comes with a built-in multi-zone streaming feature, providing a variety of streaming options across different zones in your home.
Heat Management
Some users have pointed out that the Denon AVR-X3800H tends to run hot, especially when pushed hard. This observation was noted even when using an external amplifier. Therefore, the inclusion of a cooling fan might be necessary to ensure the longevity of the receiver.
In comparison, we did not experience any significant heat issues with the Onkyo TX-RZ50 during our tests. However, this does not rule out the possibility of heat issues cropping up during extended heavy usage.
Final Verdict
In conclusion, both the Denon AVR-X3800H and the Onkyo TX-RZ50 are excellent AV receivers packed with features and deliver impressive performance.
