Main advantages Denon AVR-S660H over Pioneer VSX-934

Main advantages Pioneer VSX-934 over Denon AVR-S660H

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-S660H supports 5.2-channels sound, but Pioneer VSX-934 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 VSX-934 this value is 80/8 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-S660H 6 out of 10, and the VSX-934 - 9.

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 VSX-934.

Pure Direct mode feeds sound directly to the amplifier and bypasses any DSP processing. Only Pioneer VSX-934 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 markedly different, Denon AVR-S660H scored 7, and Pioneer VSX-934 scored 8 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, both receivers got 7 points on our 10-point scale.

Denon AVR-S660H is equipped with 6/1 HDMI inputs and outputs, and Pioneer VSX-934 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 only 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-S660H in the HDCP 2.3 version, and Pioneer VSX-934 has the HDCP 2.2 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-S660H were rated 8 out of 10 against the 10 for the VSX-934.

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-S660H works with the 4K/120Hz video, and the VSX-934 has the 4K/60Hz.

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 only on Denon AVR-S660H.

Additional features

In terms of evaluating additional features, the AVR-S660H got 10 points, but the VSX-934 has 6.

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. Only the 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

Denon AVR-S660H got 8 points for the multichannel surround sound and Pioneer VSX-934 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. Pioneer VSX-934 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 VSX-934.
