Design

Though it's not always a negative thing, the Onkyo TX-NR676 does not aim to conform to design norms. This is the straightforward, no-nonsense receiver you want that emphasizes function over form. It looks simple, boxy, with a typical black finish. There are no flashing lights or futuristic curves here, hence for me this was a comfort. If you want the emphasis on your screen or speakers instead of the AVR, it merges naturally into your entertainment system without drawing attention to itself.

The design has one drawback in terms of scale. It is hefty, like other AV receivers. Your media shelf or cabinet will require some room, and because it's on the heavier side, moving it around during setup is not exactly easy. It's not intolerable, but if you like often changing your entertainment center like me, this may be a little hassle.

The front panel lays simply and clearly. Although the right has a huge volume knob, a display in the middle, and various input buttons, first it seems a little disorganized. Though first used, I became acclimated to the button location and found myself not stumbling around as much.

Though it's not the most attractive receiver available, overall it performs functionally and does the job without bringing too much attention to itself. If you like simple design, you might find value in the subdued style.

Connectivity

The Onkyo TX-NR676 seemed to me like opening a port and input a treasure box. Its two HDMI outputs and six HDMI inputs let you quickly connect many devices—such as a Blu-ray player, game console, and streaming device—without continually changing out connections. If, like me, you balance several media sources, this is quite a benefit. Not missing any of the newest visual standards, the HDMI ports also support 4K video, HDR10, and Dolby Vision.

Apart from HDMI, the TX-NR676 is compatible with older audio equipment also because of its many optical, coaxial, and analog inputs. Streaming music from your phone or tablet is easy thanks also to Wi-Fi, Bluetooth, Chromecast built-in, and AirPlay compatibility. Especially when transitioning between casual music listening and movie viewing, I found myself utilizing Bluetooth and Chromecast more often than I anticipated.

I did observe, however, that the Bluetooth range isn't the finest. Moving too far outside the room might cause the connection to disconnect, which would be inconvenient if you were streaming music around the home. It works well, however, if you are sharing one room.

It also has Ethernet, which I found helpful for guaranteeing a consistent network connection whether streaming movies in high definition or using Spotify or Tidal. Though for continuous 4K streaming I would advise putting it straight into your network; the wifi connections are really good.

All things considered, the Onkyo TX-NR676 provides strong connection to suit both old and contemporary devices. The rather restricted Bluetooth range is the one drawback; most people would not find this to be a deal-breaker.

Performance

Given its price range, the TX-NR676 is really remarkable in performance. Built for a 7.2-channel surround sound system, this receiver allows you to connect two subwoofers and seven speakers. Using a 5.1 system in my configuration, the sound quality was clearly greater than it had been in the AVR.

Regarding movies, the Dolby Atmos and DTS support definitely caught attention. Using action films like "Mad Max: Fury Road" and "John Wick," I found the sound to be rather engaging. Whereas the conversation stayed distinct even in the loudest sequences, the explosions and gunshots exhibited depth and clarity. Dolby Atmos's overhead sound effects made a significant impact, giving the experience more 3D-like character that really drew me into the film.

The TX-NR676 most surprised me in music performance. From classical to hip-hop, I usually like listening to a combination of music; the receiver managed everything well. Bass answered solidly without overwhelming the mids and highs, and voices came over effectively. Even at gatherings, I found no distortion at greater levels. I was pushing it up. Having said that, if you're an audiophile searching for ultra-refined sound and this receiver doesn't have some of the high-end clarity some more costly versions have, you may discover that for regular listening, however, it is more than enough.

Gaming performance was likewise excellent. The 4K HDR pass-through worked well and the surround sound gave an additional degree of realism during fast-paced games like "Call of Duty" and "Spider-Man: Miles Morales," with a PlayStation 5 connected up.

One thing to bear in mind is that, particularly when running many speakers at high levels, the receiver generates some heat even if it can go loud. Though it's not too alarming, ensure your apartment has enough ventilation to prevent any overheating problems.

The Onkyo TX-NR676 provides all things considered, a fair audio experience across movies, music, and games. Though it may miss some of the finer nuances that more costly models may provide, the surround sound is immersive, and the sound quality is remarkable given the budget.

Where and When to Use

Medium to large living rooms or home theatres would find the TX-NR676 ideal. This AVR can adequately cover a room between 200 and 400 square feet with sound if you are configuring a 5.1 or 7.2 surround sound system. Using my approximately 300-square-foot living area, it worked well without seeming underpowered.

It's not restricted to simply committed home theaters, either. I also used it for gaming, music listening, and informal TV viewing; it handled all those situations without a hitch. It's flexible enough that you won't feel as if certain hobbies call for a distinct sound system.

If your area is smaller—that of a bedroom or an office—this AVR may seem excessive, but it is under control if you adjust the parameters to cut the output levels. Although for most houses it's more than enough, in bigger spaces you may choose to combine it with more powerful speakers to maximize the surround sound experience.

Compatible Devices

One of my favorite features of the Onkyo TX-NR676 was its compatibility with a broad spectrum of devices. This receiver can handle both older devices like CD players or turntables and more recent devices like a PlayStation 5, 4K Blu-ray player or an Apple TV.

Connecting my PS5, Apple TV, and an ancient DVD player proved easy. If you want to take your music system to the next level, I particularly liked that the receiver had pre-outs for attaching an additional amplifier.

Direct streaming straight from your phone or tablet is simple with the built-in Chromecast and AirPlay, which eliminate unnecessary cords. Using AirPlay from my iPhone, I routinely streamed podcasts on Spotify and found it to be flawless.

If you have smart home appliances as well, the TX-NR676 supports Google Assistant, which lets me operate the receiver using voice commands like changing the volume or switching inputs. Though it's not as broad as other smart home appliances, it provides ease for simple chores.

Ease of Use

Although setting up the TX-NR676 was not too difficult, there are quite many settings to negotiate. Since there are so many ways to personalize your audio settings, if you're a novice it might first seem a little daunting. Still, the on-screen setup tutorial is simple to follow, and everyday usage is really seamless once you get the first setting worked out.

The AccuEQ environment calibration technology changed the sound quality by helping to tune the audio depending on the acoustics of your environment. After doing the calibration with the provided microphone, the sound in my room sounded much more balanced a few minutes later.

Though not very user-friendly, the remote control is effective. There were plenty of buttons, and I needed time to recall where everything was. Fortunately, the Onkyo app for cellphones streamlines really a lot. Since the app is more navigable than the remote, I found myself utilizing it more often.

Changing between many inputs—such as from the PS5 to the Apple TV—is fast and smooth; I never found any lag or delay in audio synchronizing. Although the app and AccuEQ calibration increase its accessibility for regular users, the remote control still has to be upgraded to make it more accessible for daily users.

Cost

The Onkyo TX-NR676 is reasonably priced considering its characteristics and performance. Given the features and performance it provides, it is really cheaply priced. Along with many of networking choices, you have Dolby Atmos, DTS, 4K video capability, and 7.2 channels. Given the cost, it offers great value—especially for those looking for rich surround sound without going over their means.

Should you be an audiophile or someone seeking the best degree of audio accuracy, you may discover that the TX-NR676 falls short in terms of clarity and detail of more upscale models. For most casual users or home theater aficionados, however, it offers more than enough capability to improve your home entertainment environment.
