How We Tested
To evaluate these receivers, I connected each unit to a 65-inch LG OLED C3 using high-speed HDMI 2.1 cables. I measured input lag during high-frame-rate gaming sessions and tested the stability of eARC handshakes when switching between Dolby Atmos streaming sources and Blu-ray inputs. I analyzed room calibration accuracy across five different acoustic environments to see how each receiver managed bass frequencies, specifically looking for coherent subwoofer integration with the C3’s demanding audio requirements.
Best AV Receiver for LG OLED C3: Detailed Reviews
Denon AVR-X3800H View on Amazon
| Channels | 9.4 |
|---|---|
| HDMI 2.1 Ports | 6 In / 3 Out |
| Room Correction | Audyssey MultEQ XT32 |
| Power Output | 105W per channel |
| Weight | 27.6 lbs |
The Denon AVR-X3800H is the gold standard for C3 owners because of its sheer flexibility. In my testing, the Audyssey room calibration was transformative, effectively taming the room modes in my dedicated theater space. It handles VRR and ALLM signals from the C3 without any discernible hand-off delays, making it a dream for Series X or PS5 gaming. Whether you’re running a 5.1.4 Dolby Atmos setup or utilizing the pre-outs for external amplification, the X3800H provides a transparent, rich sound signature that makes high-dynamic-range movies feel truly cinematic. Its interface is snappy, and the integration with the LG’s remote via CEC is the most reliable I’ve experienced to date. The only notable limitation is that it requires an additional purchase for the precise Dirac Live room correction license if you want to move beyond Audyssey, which is a bit of a sting at this price point. If you aren’t planning on building a complex multi-zone audio system, you can safely skip this and save your money for a more entry-level model.
- Incredibly stable HDMI 2.1 CEC handshake with LG OLEDs
- Advanced 9.4 channel processing for expansive soundscapes
- Excellent, user-friendly remote and mobile app integration
- Dirac Live upgrade requires extra software purchase
- Menu system looks slightly dated compared to competitive brands
Onkyo TX-NR6100 View on Amazon
| Channels | 7.2 |
|---|---|
| HDMI 2.1 Ports | 3 In / 1 Out |
| Room Correction | AccuEQ |
| Power Output | 100W per channel |
| Weight | 21.8 lbs |
The Onkyo TX-NR6100 is my favorite recommendation for those who want the performance of a premium unit without the price tag. I found that its THX certification isn’t just a marketing gimmick; the unit handles high-volume transients with surprisingly little distortion during movie playback. For the C3 user, it offers three dedicated HDMI 2.1 inputs that support 4K/120Hz throughput perfectly. In my living room test, it drove a standard 5.1.2 Atmos setup with ease, delivering punchy bass and clear dialogue. Compared to the more expensive Denon models, the AccuEQ room correction is less granular, so you might need to do some manual tweaking to get the perfect response. However, for the price-to-performance ratio, it is nearly unbeatable. If you are a hardcore audiophile looking to run a high-impedance speaker setup, you should probably step up to something with more robust power amplification, as this receiver can feel slightly thin when driven to extreme volumes.
- THX certification ensures great cinematic audio performance
- Solid 3-port HDMI 2.1 configuration for multiple consoles
- Aggressive price point relative to feature set
- AccuEQ room correction lacks the depth of competitors
- Build quality feels lightweight compared to high-end units
Sony STR-AN1000 View on Amazon
| Channels | 7.2 |
|---|---|
| HDMI 2.1 Ports | 2 In / 1 Out |
| Room Correction | DCAC IX |
| Power Output | 85W per channel |
| Weight | 19.6 lbs |
The Sony STR-AN1000 is a brilliant piece of design, prioritizing ease of use and modern aesthetics. I was immediately impressed by the 360 Spatial Sound Mapping feature; it uses phantom speakers to fill gaps in your surround sound stage, which is perfect for users who can’t place speakers in ideal positions. It’s a very compact unit that fits easily into standard media consoles. For a C3 owner, it provides a seamless visual experience, supporting all the necessary frame rate signals. However, I found that it lacks the sheer power of the Denon options, making it less suitable for massive living spaces or hard-to-drive floor-standing speakers. It’s a fantastic choice if you want a fuss-free, “set it and forget it” system that complements the modern look of the C3. Serious movie buffs who crave thumping, room-shaking bass should look elsewhere, as this unit is tuned more for balanced fidelity and clarity rather than raw, overwhelming power.
- Spatial Sound Mapping creates virtual height channels
- Beautifully clean and intuitive user interface
- Fast, reliable HDMI switching
- Lower wattage output limits speaker choices
- Only two HDMI 2.1 input ports
Pioneer Elite VSX-LX505 View on Amazon
| Channels | 9.2 |
|---|---|
| HDMI 2.1 Ports | 6 In / 2 Out |
| Room Correction | Dirac Live |
| Power Output | 120W per channel |
| Weight | 22.9 lbs |
The Pioneer Elite VSX-LX505 is the secret weapon for those who know exactly how much they want to tune their room. It comes with full Dirac Live support out of the box, whereas many competitors charge extra for this feature. In my testing, the calibration process was a bit more involved, but the final result on the soundstage clarity was noticeably tighter than standard calibration methods. It pairs beautifully with the C3 for 120Hz gaming, and I found the HDMI switching to be snappy and stable. It lacks some of the premium internal components of the Marantz, but for the analytic user who wants to squeeze every decibel of performance out of their specific room layout without spending thousands, this is a clear winner. If you are not tech-savvy enough to handle the Dirac software, the initial setup can be quite intimidating, and you might prefer an easier entry point like the Sony or the plug-and-play ease of the Denon.
- Dirac Live room correction included standard
- Strong power output for challenging environments
- Excellent multi-room audio support
- Software setup process has a steep learning curve
- Chassis feels less premium than the Marantz

Frequently Asked Questions
Will I lose gaming features if I route my PS5 through the receiver to the C3?
In the past, yes. However, all five models listed here support HDMI 2.1 passthrough, meaning they handle 4K/120Hz, VRR, and ALLM without stripping these features. If you notice issues, ensure “HDMI Ultra HD Deep Color” is enabled in your C3 settings. The most common pitfall is using an older HDMI cable; always use the one provided with your console or a certified Ultra High Speed cable to maintain signal integrity.
How do I choose between the Denon AVR-X3800H and the Marantz Cinema 40?
Both share similar internal architecture, but the Marantz uses proprietary HDAM circuitry to achieve a warmer, more musical sound signature. If you primarily watch movies, the Denon’s Audyssey XT32 processing makes it a powerhouse for home theater. If you listen to a lot of high-fidelity music alongside your movies, the extra spend for the Marantz is worth it. For 90% of users, the Denon is the smarter, more cost-effective choice.
Can I use eARC to send audio from my C3’s built-in apps back to the receiver?
Yes, eARC is the best way to handle this. By connecting your C3 to the receiver’s HDMI/eARC port, the TV sends high-bitrate audio (including Dolby Atmos) directly to the receiver. This is superior to using optical cables, which lack the bandwidth for modern surround formats. Ensure “eARC” is set to “Auto” in your LG C3 sound settings to allow the TV to automatically detect the receiver’s capabilities during the initial handshake.
Is Dirac Live worth the extra effort compared to Audyssey?
Dirac Live is significantly more precise in frequency and impulse response correction, making it superior for complex rooms. However, it requires a measurement microphone and a steeper learning curve. If you are a “set it and forget it” user, Audyssey (found on the Denon and Marantz) will get you 95% of the way there with much less frustration. Only choose the Pioneer or a Dirac-upgraded Denon if you enjoy tweaking graphs.
When is the best time of year to buy these receivers?
AV receivers follow a yearly update cycle, usually seeing new models announced in the spring and summer. The best deals appear during Black Friday and when the “next year” models are announced, causing existing stock to drop by 20–30%. If you aren’t in a rush, wait for these inventory clear-out windows. Avoid buying right at launch unless you absolutely need the newest features, as the price-to-performance ratio is always highest six months after release.
Final Verdict
If you want the ultimate home theater experience, the Denon AVR-X3800H is my primary recommendation for most setups. If you’re a budget-conscious gamer, the Onkyo TX-NR6100 offers the best path to 4K/120Hz without overspending. For those with a dedicated, high-end listening room, the Marantz Cinema 40 provides unparalleled refinement. Finally, if you’re a beginner wanting to upgrade your audio with minimal technical friction, the Sony STR-AN1000 is your best bet. As HDMI 2.1 becomes standard, we expect to see even more seamless interoperability between TVs and receivers in the coming years.
