Main advantages Denon AVR-S940H over Denon AVR-S660H

Main advantages Denon AVR-S660H over Denon AVR-S940H

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 Denon AVR-S940H 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 AVR-S940H this value is 90/8 W/Ohm, and for the AVR-S660H it is 75/8 W/Ohm.

Audio features

After reviewing the audio features of each model, we can rate the AVR-S940H 7 out of 10, and the AVR-S660H - 6.

Pure Direct mode feeds sound directly to the amplifier and bypasses any DSP processing. Only Denon AVR-S940H 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.

Connectivity

The connectivity of competitors in our comparison is equal and was rated 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, Denon AVR-S940H got 9 points, but Denon AVR-S660H received 7 points.

Denon AVR-S940H is equipped with 8/2 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 Denon AVR-S940H in the HDCP 2.2 version, and Denon AVR-S660H has the HDCP 2.3 version.

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-S940H 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 AVR-S940H 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.

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

Denon AVR-S940H got 7 points for the multichannel surround sound and Denon AVR-S660H got 8.

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-S940H 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 only on the AVR-S940H.
