The Onkyo TX-RZ810 looks stunning at first glance!

From the numerous connectivity options to a plethora of features for you to play with, this is the Onkyo TX-RZ810. Despite not having upgraded much in terms of the body, Onkyo truly went above and beyond to make sure that the TX-RZ810 leaves a trail for others to follow. It supports internet streaming and manages to do that very quickly too with the Ethernet port. The new DAC that Onkyo opted to go for has proven to be quite in their favor. It makes sure that the sound quality does not degrade and you hear exactly what you intend to do, even when using the TX-RZ810 to power the most demanding speakers. Moreover, the AccuEQ automatically optimizes the equalizer settings for your speakers depending on your room. So right off the bat, you are greeted with amazing sound.

You will find that there is very little to complain about the TX-RZ810. In fact, for the most part, you can even ignore what little downsides this A/V receiver has. Some Onkyo veterans might find the lack of a major body upgrade to be a downer, but we found it to be a cause of very little concern. The AccuEQ version in the TX-RZ810 is a newer one that Onkyo adapted. It chooses even better settings, however, takes more time to do so. That comes with it taking in more amounts of readings to find the right settings for you.


Onkyo had been known to have used the same chassis with slightly different upgrades in their previous models. The TX-RZ810 follows a different model with it having a new and revamped chassis. The biggest upgrade from the previous chassis is the addition of a large LCD display that adds to the aesthetics as well. Really, a step in the right direction. The LCD display is a really pleasant addition along with an entirely new pre-amp section. The front panel of the TX-RZ810 is filled with useful knobs and buttons as Onkyo makes sure that they maximize the potential of the large front panel. However, this does end up making the A/V receiver slightly bigger than the rest.

A Basic Minimal Design does wonder.

On the left side of the panel are three knobs. The two knobs on the lower left corner are used to adjust the tone and switch between listening modes. And on the top is the power button along with a toggle button for Pure Audio. And moving on to the right side, you’ll see that all the buttons for source input, Bluetooth, Zone 2 and 3 are present. On the bottom right corner is a large knob which is the master volume. There are a total of 15 buttons on the right, with various toggle modes and features. These buttons are the ones primarily used for switching between connectivity and the majority of other things.

And lastly, in the middle, you’ll find the large LCD display, the highlight of the aesthetics department of the TX-RZ810. It works well in displaying the desired information at bright levels, visible over longer distances due to the large size. In the middle are more buttons- sleep, music optimizer, sleep and many more. The HDMI, AUX mic and phone inputs are also located in the front middle portion of the TX-RZ810.

The included remote controller is basic and handy just like the receiver itself.

Use and Setup

The TX-RZ810 is able to easily handle multi-room music playing with its ports being able to fit up to eleven speakers. This really leaves a lot of wiggle room for high and flexible auditory configurations. Its 5.2 surround channel is more than enough for indoor sound needs. And if you’re looking for more, switch to the Zone 2 power mode and the TX-RZ810 will deliver optimum stereo sound even in outdoors. This 7.2 A/V receiver has 200 Watts into 6 Ohms and 130 Watts into 8 Ohms rated power rating. Along with packing in immense power in here, it also features eight HDMI ports compatible with 4K at 60Hz.

In terms of connectivity, you have six analog inputs including a phono section, digital coax inputs, optical and USB. There is a lot of room for you to work with here leaving little to fret over. And the networking capabilities come with an even better surprise. Pandora, Spotify, Deezer, Apple AirPlay and even GoogleCast. Onkyo says that they will be updating all of these features and keep on doing so with frequent firmware updates.


The TX-RZ810 features a number of easy to access, wireless functions that are not just easy to control but a charm as well. Starting off, the WiFi features. Using the WiFi, you can directly access music stored in your PC and have it play off of the speakers. Streaming platforms like Spotify, Pandora are also a possibility with this A/V receiver.


Additionally, there’s also an Onkyo app for tablet or mobile phone with which you can connect the TX-RZ810 over Bluetooth. This will let you have even more control and play music straight from the connected device to this A/V receiver.

The TX-RZ810 features Onkyo’s AccuEQ Room Calibration and it helps calibrate the settings on its own. This one is a newer version and it does take a little more time than the previous AccuEQ however that’s due to it taking in more readings. Applying the EQ calibrations are totally on the user but they do make a difference. Add that with the 1 dB incrementing adjustable equalizer and you can really make it all boom.

The Internals

With the RZ810, Oknyo opted to go for the AKM AK4458 DAC from Asahi Kasei. With this newly employed preamp and the 384 kHz / 32-bit AKM AK4458 DAC, the bass section ends up in a much more improved state with the receiver granting higher control over the speakers and subwoofers. The highs and lows in the frequencies are even more accurate, fluent and provide a better sounding image. Everything flows like a cinch and the naturality feels like it has almost been perfected.

When listening to music, you can choose to toggle between different modes. For our testing, we listened to different genres of music on Spotify on the Pure Music and Direct modes. For strictly music listening, we do recommend you use either of these modes as they disengage any extra signal processing. The TX-RZ810 was able to deliver a precise and clear sounding image which remained consistent even in high frequencies. The midrange is very balanced and controlling the speakers properly, you can have the most natural and clear sounding vocals that you can imagine.


The Onkyo TX-RZ810 has specifically engineered this A/V receiver to be a powerful sounding device. Not only does it excel in delivering ample power to the speakers, but its amazing control also makes sure that you are getting the most out of them. The agility, dynamics and powerful range of the Onkyo TX-RZ810 comes alive with its great transformers and good sounding DAC. The design of the exterior is not that different from the TX-RZ800 model but the sound is surely a step forward. Packed with tonnes of features, this A/V receiver is one of the most loved and demanded ones in the current market.
