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, Sony STR-DH590 got 6 points, but Denon AVR-S970H received 8 points.
Sony STR-DH590 is equipped with 4/1 HDMI inputs and outputs, and Denon AVR-S970H has 6/2 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-S970H.
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 Sony STR-DH590 in the HDCP 2.2 version, and Denon AVR-S970H 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-S970H has a Phono interface.

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 STR-DH590 were rated 6 out of 10 against the 10 for the AVR-S970H.
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 STR-DH590 works with the 4K/60Hz video, and the AVR-S970H 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-S970H.
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-S970H.
