Based on the data on the characteristics and features of both models, we can conclude that TX-RZ820 has better performance than AVRS530BT.
For the built-in amplifier, the devices received different marks - 9 and 6, respectively, on a 10-point scale.
The number of channels is equal to the number of possible connected speakers. The Onkyo TX-RZ820 supports 7.2-channels sound, but Denon AVRS530BT supports a 5.2-channels configuration.
RMS stands for the actual power of the receiver. The higher this value, the louder the sound can be produced. The differences between the models in terms of RMS power are significant - for the TX-RZ820 this value is 160/8 W/Ohm, and for the AVRS530BT it is 70/8 W/Ohm.
|Stereo power (RMS), W/Ohm||160/8||70/8, 90/6|

After reviewing the audio features of each model, we can rate the TX-RZ820 8 out of 10, and the AVRS530BT - 5.
Bi-amping is the amplification of one speaker with two amplifiers. This amplification method has a positive effect on sound quality. Bi-amping is possible only on the TX-RZ820.
Pure Direct mode feeds sound directly to the amplifier and bypasses any DSP processing. Only Onkyo TX-RZ820 has Pure Direct mode.
Most receivers now come with a microphone included. It is with the help of this microphone that the auto-calibration system functions, which adjusts the sound of the receiver to the room.
