The Denon HEOS AVR versus Onkyo TX-NR585 comparison makes clear all pros and cons of AV receivers. According to the results of our review, Denon HEOS AVR received 4.8 points out of 10 possible, and Onkyo TX-NR585 was rated 7.4 points. The release date of HEOS AVR is 2017, and TX-NR585 is 2018. Identified advantages have shown that TX-NR585 is better over HEOS AVR mainly as a home theater processor.
For the built-in amplifier, the devices received different marks - 6 and 8, respectively, on a 10-point scale.
The number of channels is equal to the number of possible connected speakers. The Denon HEOS AVR supports 5.1-channels sound, but Onkyo TX-NR585 supports a 7.2-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-NR585 this value is 80/8 W/Ohm, and for the HEOS AVR it is 50/8 W/Ohm.
|Stereo power (RMS), W/Ohm||50/8, 65/6||80/8, 170/6|
|Output impedance, Ohm||8, 6||8, 6|
|THD in stereo, %||0.05||0.08|
After reviewing the audio features of each model, we can rate the HEOS AVR 5 out of 10, and the TX-NR585 - 9.
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 on the TX-NR585.
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.
