It’s for the everyday audiophile who wants a reliable centerpiece for their home theater without the fuss or frills.

The Onkyo TX-NR555 doesn’t scream for attention with its design; its low-key vibe is all about blending in. It’s light enough to move without throwing your back out, but that might make you wonder if it’s a bit too delicate for a house with kids or pets. It’s got a clean face, an easy-to-read display, and enough buttons to make you feel in control without needing a pilot’s license. However, some users have found the LED display to be outdated, resembling an '80s calculator, which may not appeal to those who prefer a more modern aesthetic
On the connectivity front, the TX-NR555 is equipped with six HDMI inputs, providing ample connections for all your devices. With support for 4K/60Hz pass-through and 080p to 4K upscaling, it ensures compatibility with the latest video formats and technologies. The inclusion of built-in Wi-Fi and Bluetooth technologies allows for easy streaming from various devices, making it a central hub for all your digital entertainment needs.
The receiver also supports AirPlay, Chromecast, and various streaming services like Spotify and Tidal, offering a plethora of options for accessing your favorite music and content. Although it lacks some newer features like eARC and HDR10+, the TX-NR555 still provides a solid foundation for most home entertainment systems
The TX-NR555 boasts a 7-channel amplifier with 80 watts per channel1, ensuring a robust and dynamic soundstage. Its ability to handle Dolby Atmos and DTS:X formats means it can deliver a truly immersive audio experience, perfect for movie enthusiasts looking to recreate a theater-like atmosphere at home. The receiver’s frequency response ranges from 10Hz to 100kHz, which contributes to its ability to produce clear mids, sparkling highs, and deep lows. This wide range ensures that whether you’re listening to classical music, enjoying the latest blockbuster, or playing a video game, the sound will be rich and detailed.
The TX-NR555 shines in its ability to balance the lows, mids, and highs. The lows are deep enough to give weight to explosions and bass lines without overpowering the rest of the audio spectrum. The mids are well-defined, ensuring dialogue and main melodies are clear and present. The highs are crisp, adding a level of detail that brings out the nuances in music and sound effects. This balance makes the TX-NR555 suitable for a variety of audio purposes, from casual listening to more critical audio work like mixing or editing.
However, at max volume, the bass might start to feel a bit muddy. Users have also reported difficulties with audio sync, particularly when using Direct mode. This could be problematic for those who are sensitive to lip-sync errors in movies or TV shows
This receiver is perfect for your everyday living room or bedroom setup. It’s great for those who love their movies and music but don’t need to shake the rafters off. If you’re hosting a block party, though, you might need something with more oomph.
The TX-NR555 is pretty much a ‘come one, come all’ kind of receiver. It’s ready to play nice with everything from your vintage record player to the latest 4K streaming device. Just keep in mind, as the tech world speeds ahead, this receiver might not be able to keep up forever.
Onkyo’s got you covered with an easy setup that won’t have you pulling your hair out. The remote is straightforward, and there’s even a phone app to make tweaks on the fly. But, it’s 2024, and not having some of the latest features might make it feel a bit behind the curve for the tech-savvy. The Onkyo controller app has also been criticized for not being user-friendly, which could detract from the overall user experience
The TX-NR555 hits that sweet spot of giving you a bang for your buck. It’s not the cheapest on the market, but it’s also not going to cost you an arm and a leg. It’s a solid middle-of-the-road option that offers good value for the price.
