Let's make the Denon AVR-X3600H versus Denon AVR-S750H comparison. According to the results of our review, Denon AVR-X3600H received 8.7 points out of 10 possible, and Denon AVR-S750H was rated 7 points. Both AV receivers were introduced in 2019. After comparison, it will become clear that among these two devices, the AVR-X3600H is more suitable for the role of the heart of home theater system.
For the built-in amplifier, the devices received different marks - 8 and 7, respectively, on a 10-point scale.
The number of channels is equal to the number of possible connected speakers. The Denon AVR-X3600H supports 9.2-channels sound, but Denon AVR-S750H 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 AVR-X3600H this value is 105/8 W/Ohm, and for the AVR-S750H it is 75/8 W/Ohm.
|Stereo power (RMS), W/Ohm||105/8, 135/6||75/8, 110/6|
|Output impedance, Ohm||8, 6||8, 6|
|THD in stereo, %||0.08||0.08|
After reviewing the audio features of each model, we can rate the AVR-X3600H 8 out of 10, and the AVR-S750H - 6.
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 AVR-X3600H.
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.
Speaker A/B switching allows you to change between the main and sub speaker set. Denon AVR-X3600H can work with the main and additional set of speakers - and switch between them.
