An overview of Pioneer VSX-531 and Denon AVR-X2300W will help us understand the many features that the devices are equipped with. According to the results of our review, Pioneer VSX-531 received 4.3 points out of 10 possible, and Denon AVR-X2300W was rated 7.2 points. Both AV receivers were introduced in 2016. And as a result of the review, it becomes clear that VSX-531 is inferior in audio processing features to AVR-X2300W.
For the built-in amplifier, the devices received different marks - 6 and 7, respectively, on a 10-point scale.
The number of channels is equal to the number of possible connected speakers. The Pioneer VSX-531 supports 5.1-channels sound, but Denon AVR-X2300W 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-X2300W this value is 95/8 W/Ohm, and for the VSX-531 it is 80/8 W/Ohm.

After reviewing the audio features of each model, we can rate the VSX-531 6 out of 10, and the AVR-X2300W - 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 AVR-X2300W.
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-X2300W can work with the main and additional set of speakers - and switch between them.

Pioneer VSX-531 got 5 points for the multichannel surround sound and Denon AVR-X2300W got 7.
Dolby Atmos' particularity is that this is the object-oriented sound format, that is, each audio signal object is independently sounded and connected to its spatial position. Denon AVR-X2300W can create 3D sound due to the Dolby Atmos support.
DTS:X is an algorithm used by the processor to create sound scenes, where sounds connected directly to objects rather than channels, and to determine the optimum sound output distribution in space. Surround sound with DTS:X is available on the AVR-X2300W.
