Of course, if getting the best audio quality from your home theater system is what you want, a simple sound bar is not going to be sufficient. It may offer a very good upgrade from the built-in speakers in your TV, but it lacks the power to send out those thundering bass that makes a truly vivid and realistic entertainment experience. If you really want to get the best, you need a decent AV receiver. With a decent receiver, even if the device is paired with just entry-level speakers, you can take the audio quality to a completely new level.
Onkyo has been considered as one of the best brands when it comes to an AV receiver. The company has released various models that have satisfied many consumers. Currently, two of the most popular ones are Onkyo TX RZ710 and Onkyo TX NR757. Notice that they come from different lines; Onkyo TX RZ710 comes from the RZ line whereas Onkyo TX NR757 comes from the NR line. In addition, Onkyo TX RZ710 is standing at a higher price point than Onkyo TX NR757. So, how do these two models compare against each other? Is the price jump from Onkyo TX NR757 to Onkyo TX RZ710 really worth the money? See the comparisons below to determine the answer.
Onkyo TX RZ710 vs. Onkyo TX NR757: Design
In terms of design, you will not notice much of a significant difference. The two models have exactly the same width and depth, 435 mm and 378 mm respectively. Onkyo TX RZ710 is just slightly taller (177 mm) than Onkyo TX NR757 (173.5 mm) due to accommodating several more ports on the rear panel. Onkyo TX RZ710 (23.1 lbs) is also slightly heavier than Onkyo TX NR757 (22 lbs). As you can see, the differences of dimensions are rather trivial.
The two models also have quite a similar layout. On the front panel of each, you can find three ports on the lower right corner for the setupmic, audio, and HDMI inputs, as well as a headphone output under the display. However, note that the display of Onkyo TX RZ710 has white font whereas Onkyo TX NR757 has green font. By the way, someone may find this information useful: Onkyo TX RZ710 has a removable power cord, whereas Onkyo TX NR 757’s power cord is not removable.
Onkyo TX RZ710 vs. Onkyo TX NR757: Inputs and Outputs
Both Onkyo TX RZ710 and Onkyo TX NR757 are designed for 7.2 setups. They each have two subwoofer outputs. Each has two optical digital inputs, one coaxial digital input, and eight HDMI inputs. Still, if you compare the input and output capabilities of the two models, you can see that Onkyo TX RZ710 offers some advantages over Onkyo TX NR757. Depending on your setup and preference, these advantages may be either what you are looking for or not too important. The first upgrade that Onkyo TX RZ710 offers is that it comes with preamp outs for the main speakers, allowing you to add amps later if needed. Onkyo TX NR757 does not have these preamp outs for the main speakers. If you plan to further upgrade your setup with great amps, this is nice. Otherwise, this is not necessary. The second upgrade is that Onkyo TX RZ710 comes with HDMI outs for Zone 2, which you can use for multi-room video. Onkyo TX NR757 only has audio outs for Zone 2, but does not have HDMI outs for Zone 2. Howsoever, these upgrades are not really important for most people and will only be valuable if you are really going to use them.
Onkyo TX RZ710 vs. Onkyo TX NR757: Features
Both models are Internet-ready and Bluetooth-compatible, allowing for seamless wireless connectivity. Both also support Apple AirPlay, Google Chromecast, and Spotify Connect. Both support HDMI Standby Pass-Through. For sure, both already come with HDCP 2.2 for displaying premium 4K video content. However, while both support composite/component video conversion to HDMI as well as 1080p to 4K upscaling, only Onkyo TX RZ710 that supports HDMI to HDMI upconversion. Onkyo TX NR757 doesn’t.
For speaker calibration, both Onkyo TX RZ710 and Onkyo TX NR757 are already armed with AccuEQ with AccuReflex. The technology is excellent, and it is capable of setting up the speakers automatically for the best audio quality that suits your room’s acoustics. The calibration process is very simple.
In the processing area, there isn’t much of a difference between the two models. They both are packed with Dolby Atmos, Dolby True HD, Dolby DD Plus, DTS:X, and DTS-HD Master Audio. Both also feature the Onkyo Game Surround Modes, which feature four audio presets (Rock, Action, RPG, Sports) to deliver an immersive gaming experience. Both are armed with 384k/32-bit DACs. However, it is interesting that the overall frequency response range of Onkyo TX RZ710 is slightly wider than Onkyo TX NR757. The extra length goes to the lower frequencies. While Onkyo TX NR757 is capable of producing bass as deep as 10 Hz, Onkyo TX RZ710 can reach even deeper to 5 Hz. So, you can expect the bass performance of the RZ receiver to be slightly better than the NR model.
Onkyo TX RZ710 vs. Onkyo TX NR757: Warranty
Last but not least, we should also note down the offered warranties. Onkyo TX RZ710, coming from a higher line, seems to offer a better build quality, and it is reflected by the longer warranty. It is given a 3-year warranty. On the other hand, Onkyo TX NR757 is only given a 2-year warranty.

So, which model should you pick? In general, Onkyo TX RZ710 is the way to go if you really need the HDMI outs for Zone 2 or the preamp outs for main speakers. Of course, it also offers some other improvements, such as the HDMI to HDMI upconversion and the slightly better bass performance, but these alone are more of plus points and don’t make up the value for the price jump. If you don’t need the HDMI outs for Zone 2 or the preamp outs, Onkyo TX NR757 is sufficient.
