Main advantages Onkyo TX-SR383 over Denon AVR-X2500H

Main advantages Denon AVR-X2500H over Onkyo TX-SR383

Amplifiers

For the built-in amplifier, the devices received different marks - 7 and 8, respectively, on a 10-point scale.

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. The differences between the models in terms of RMS power are significant - for the TX-SR383 this value is 100/8 W/Ohm, and for the AVR-X2500H it is 95/8 W/Ohm.

Audio features

After reviewing the audio features of each model, we can rate the TX-SR383 6 out of 10, and the AVR-X2500H - 10.

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-X2500H.

Pure Direct mode feeds sound directly to the amplifier and bypasses any DSP processing. Only Denon AVR-X2500H 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.

Speaker A/B switching allows you to change between the main and sub speaker set. Denon AVR-X2500H can work with the main and additional set of speakers - and switch between them.

Connectivity

The connectivity of competitors in our comparison is markedly different, Onkyo TX-SR383 scored 6, and Denon AVR-X2500H scored 7 out of 10.

Wireless connection via Wi-Fi is possible on the Denon AVR-X2500H.

Bluetooth connection is now one of the main communication protocols for the receiver's control or even music broadcasting.

Streaming services

Now music streaming services are gaining more and more popularity. They allow users to listen to millions of songs by subscription.

Extensive connections

The presence of many connectors makes the receiver more versatile. But there are also narrowly targeted models, the number of connectors which are limited to a certain area of use. And when choosing their own receiver, users need to consider exactly your goals for using the receiver. For extensive connection, Onkyo TX-SR383 got 6 points, but Denon AVR-X2500H received 8 points.

Onkyo TX-SR383 is equipped with 4/1 HDMI inputs and outputs, and Denon AVR-X2500H has 8/2 HDMI inputs and outputs.

Connecting a vinyl player or phonograph is possible using a Phono input which is represented by mini-jack or RCA connectors. Only the AVR-X2500H has a Phono interface.

Video features

The AV receiver is the heart of the home theater. And in this case, support for all current video formats ensures the best user experience, so it is very important to consider this when choosing a device. Video features of rivals in our comparison were rated 6 out of 10.

Additional features

In terms of evaluating additional features, the TX-SR383 got 4 points, but the AVR-X2500H has 10.

Voice control allows you to control the basic functions of the receiver through a smartphone, smart speaker or using the microphone that comes with the kit. The AVR-X2500H can be controlled by voice via Amazon Alexa, Google Assistant, Siri, Josh.AI. Denon AVR-X2500H has the ECO mode.

Multi-room

As the center of a home media system, each multichannel receiver has an additional set of terminals for connecting the second set of speakers to create additional audio space in Zone 2 or even Zone 3 where audio can have the separate source.

Multichannel surround

Onkyo TX-SR383 got 5 points for the multichannel surround sound and Denon AVR-X2500H 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-X2500H 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-X2500H.
