The receiver for your - Onkyo TX-RZ830 vs Denon AVR-X4400H

How to choose the right model - Denon AVR-X4400H or Onkyo TX-RZ830?
I have tested both models and this short comparison will help you choose between these solutions.

The Onkyo model supports Sonos and it is THX certified, while the Denon model features DDSC-HD audio circuitry with multi-channel processing, audio is processed clearly (Onkyo uses AccuEQ and Denon uses Audyssey MultiEQ). These models support 4K with HDR10 and BT2020. The 60Hz technology excludes any motion blurring.
Connections & Setup
Onkyo TX-RZ830 supports Chromecast and Google Assistant, while Denon AVR-X4400H supports the HEOS technology. Both receivers support audio streaming and AirPlay.
These receivers support 3 powered zones. The content playing can be controlled via an application or a remote. The input ports assure a perfect connection. Both manufacturers have special applications for tablets or smartphones to control various parameters.
Both models have the auto audio calibration feature (the necessary equipment is included). If you are not satisfied (some customers are), you can always tweak it with a user-friendly application.
Design
The Onkyo model has three knobs, a power on/off button and many small buttons on the right side to change the input or control zone 2 and 3, turn Bluetooth on/off, etc. The LCD display shows some basic information only. The front flap covers more buttons and ports (HDMI, phones, setup mic).
Denon AVR-X4400H has two large knobs and a power on/off button. The LCD display provides you with some basic information. The front flap covers additional buttons and ports (aux, HDMI, USB, setup mic). The remote controller has many buttons located close to each other, so you can press something accidentally.
The back panels of both models look almost the same – many ports, but everything is labeled properly.
The shipping size is 15.7x17.2x8 in for Onkyo versus 17.1x15.3x6.6 in for Denon. The weight is 31 and 30.2 pounds respectively.
