I had an opportunity to test both models and I would provide you with the comparison of Onkyo TX-RZ820 vs Onkyo TX-RZ830.
Both models are THX-certified. They also support 4K at 60 Hz. HDR10 and Dolby vision guarantee great video quality with vivid colors. The total power output is where we see the difference between Onkyo TX-RZ820 vs TX-RZ830 – 980 W for RZ830 versus 900 W for RZ820. Moreover, RZ830 supports the Sonos sound system.
These receivers have components that let you access various internet services (RZ830 also supports the Chromecast technology). Everything can be controlled via an Onkyo application. Both models support powered zone 2 and 3 playing different content in separate zones. Inputs are another difference between Onkyo TX-RZ820 vs TX-RZ830, since RZ830 has 7 AV inputs, while RZ820 has 2 only. In the case of RZ820 – you can use only 1-3 HDMI ports with the Zone 2. Some customers claim that RZ820 has some issues with ports. Onkyo uses the AccuEQ system to control the audio output. The automatic calibration produces great results. The AccuEQ system is easy to tweak. Onkyo provides you with everything necessary for the calibration process. Customers claim that it is easy.
These models have a similar design – it has a simple LCD, two small knobs on the left side and a big one on the right side. There are many small buttons on the right side that let you control the input and zones. The front flap covers additional buttons and ports. The distance between buttons is enough to avoid pressing a wrong button. The remote controller is enough to control the receiver, but some customers claim that the remote controller is quite small and you may press a button accidentally. The shipping size of Onkyo TX-RZ830 is 15.7x17.2x8 versus Onkyo TX-RZ820 15.6x17.1x7.9. The weight is the same – 31 pounds.
