Amplifiers

For the built-in amplifier, the devices received different marks - 7 and 6, respectively, on a 10-point scale.

The number of channels is equal to the number of possible connected speakers. The Onkyo TX-SR383 supports 7.2-channels sound, but Denon AVR-S660H supports a 5.2-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-S660H it is 75/8 W/Ohm.

Audio features

The score for audio features is 6 of 10 for both receivers.

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.

Connectivity

The connectivity of competitors in our comparison is markedly different, Onkyo TX-SR383 scored 6, and Denon AVR-S660H scored 7 out of 10.

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-S660H received 7 points.

Onkyo TX-SR383 is equipped with 4/1 HDMI inputs and outputs, and Denon AVR-S660H has 6/1 HDMI inputs and outputs.

HDMI eARC is the next step in the development of audio return channel technology, which works in conjunction with HDMI 2.1. Using eARC provides the highest sound quality for home audio systems. HDMI eARC is available on Denon AVR-S660H.

The HDCP encryption protocol is now mandatory for most media devices. This security technology encrypts digital signals from one product to another. HDCP content-encryption protocol is present on Onkyo TX-SR383 in the HDCP 2.2 version, and Denon AVR-S660H has the HDCP 2.3 version.

Connecting a vinyl player or phonograph is possible using a Phono input which is represented by mini-jack or RCA connectors. Only the AVR-S660H 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 the TX-SR383 were rated 6 out of 10 against the 8 for the AVR-S660H.

With the 4K pass-through feature, the AV receiver sends "native" 4K signals to a 4K TV from a video source without any processing. The TX-SR383 works with the 4K/60Hz video, and the AVR-S660H has the 4K/120Hz.

The AV receiver passes "native" 8K signals from a video source to 8K TV without any encoding, with the 8k pass-through features. The 8K path-through is available on Denon AVR-S660H.

Most of the AV receivers have a video scaling function, it is the process of reformatting the video signal to a higher resolution without losing the quality of the image. Upscaling the video signal resolution is possible with Denon AVR-S660H.

Additional features

In terms of evaluating additional features, the TX-SR383 got 4 points, but the AVR-S660H 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-S660H can be controlled by voice via Amazon Alexa, Google Assistant, Siri, Josh.AI. Denon AVR-S660H 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-S660H got 8.
