I have tested both models and this comparison should help you choose between Onkyo TX-NR787 vs TX-RZ630.
Both models support the 9.2 channel setup. If we compare Onkyo TX-RZ630 vs Onkyo TX-NR787 in terms of the total power output, then we see that TX-NR787 wins with its 900 W versus TX-RZ630 that outputs 810 W. These receivers are THX certified. Both models support Dolby Atmos, DTS:X and DTS Neural:X. These models also support the modern video standard – 4K at 60 Hz with HDR10 and HLG. Both models support the Sonos technology.
These receivers have wireless modules that allow you access to numerous online streaming services. Both models also have the Chromecast technology and they work with the Google Assistant service.
Both models support three zones that can be easily controlled via an application or a remote controller.
These receivers are built-well and the input ports can assure a perfect connection without any noise. There are many different kinds of ports so you can connect almost all the devices you have. Both models have 7 in and 2 out HDMI ports.
Onkyo uses the AccuEQ technology for audio controlling. The auto-calibration feature is quite precise. Onkyo also provides you with the required microphone. However, if you are not satisfied with the result, you can always use a special application and fine-tune the AccuEQ to get the sound you want.
Comparing Onkyo TX-RZ630 vs TX-NR787 in terms of their design, we will not see many differences. Both models have three knobs (one large and two small ones), a simple LCD, a row of buttons and some extra input ports, including the one for the setup microphone. The buttons are large enough to avoid clicking something accidentally. Moreover, everything is labeled properly.
The dimensions are 15x17.3x6.9 inches for TX-NR787 and 15x17.2x7 inches for TX-RZ630. The weight is 24 pounds and 22.5 pounds respectively.
