Main advantages Sony STR-AZ1000ES over Denon AVR-S670H

Amplifiers

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 Denon AVR-S670H supports 5.2-channels sound, but Sony STR-AZ1000ES 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 STR-AZ1000ES this value is 100/8 W/Ohm, and for the AVR-S670H it is 75/8 W/Ohm.

Audio features

After reviewing the audio features of each model, we can rate the AVR-S670H 6 out of 10, and the STR-AZ1000ES - 8.

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 STR-AZ1000ES.

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-S670H 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, Denon AVR-S670H scored 7, and Sony STR-AZ1000ES scored 8 out of 10.

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

DLNA is the perfect way to use your local cloud storage to stream movies and music directly to a TV. You can use the DLNA protocol only with Sony STR-AZ1000ES.

MHL combines the functionality of the HDMI and MicroUSB interfaces and lets you connect any mobile devices to a receiver. The STR-AZ1000ES has MHL support for streaming content from external devices.

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, Denon AVR-S670H got 7 points, but Sony STR-AZ1000ES received 8 points.

Denon AVR-S670H is equipped with 6/1 HDMI inputs and outputs, and Sony STR-AZ1000ES has 6/2 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-S670H 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 AVR-S670H were rated 8 out of 10 against the 9 for the STR-AZ1000ES.

Additional features

In terms of evaluating additional features, both receivers received a score of 10 out of 10.

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

For the ability to create multichannel surround sound, each of the receivers received 8 points out of 10.

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. Sony STR-AZ1000ES 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 STR-AZ1000ES.

IMAX Enhanced is a licensing and certification program under which home theater devices deliver crisp 4K HDR pictures and powerful sound as it was designed by the IMAX engineers. The STR-AZ1000ES licensed by IMAX.
