Let's make the Denon AVR-S760H versus Onkyo TX-NR686 comparison. According to the results of our review, Denon AVR-S760H received 7.4 points out of 10 possible, and Onkyo TX-NR686 was rated 7.2 points. The release date of AVR-S760H is 2021, and TX-NR686 is 2018. After comparison, it will become clear that among these two devices, the AVR-S760H is more suitable for the role of the heart of home theater system.
For the built-in amplifier, the models have rated 7 points out of 10.
The number of channels is equal to the number of possible connected speakers. Both receivers can handle the 7.2-channels configuration.
RMS stands for the actual power of the receiver. The higher this value, the louder the sound can be produced. In terms of RMS power, the models have the same characteristics - 75/8, 165/6/6 W/Ohm.
|Stereo power (RMS), W/Ohm||75/8, 165/6||165/6|
|Output impedance, Ohm||8, 6||6|
|THD in stereo, %||0.08||0.08|
After reviewing the audio features of each model, we can rate the AVR-S760H 6 out of 10, and the TX-NR686 - 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-NR686.
Pure Direct mode feeds sound directly to the amplifier and bypasses any DSP processing. Only Onkyo TX-NR686 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.
