Let's compare Onkyo TX-RZ620 versus Denon HEOS AVR for an overview of all their pros and cons. According to the results of our review, Onkyo TX-RZ620 received 7.1 points out of 10 possible, and Denon HEOS AVR was rated 4.8 points. Both AV receivers were introduced in 2017. And as a result of the comparison, TX-RZ620 seems to be a better option for the role of a home theater center than HEOS AVR.
For the built-in amplifier, the devices received different marks - 7 and 6, respectively, on a 10-point scale.
The number of channels is equal to the number of possible connected speakers. The Onkyo TX-RZ620 supports 7.2-channels sound, but Denon HEOS AVR supports a 5.1-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-RZ620 this value is 100/8 W/Ohm, and for the HEOS AVR it is 50/8 W/Ohm.
