Main advantages Denon AVR-S640H over Marantz NR1710

Main advantages Marantz NR1710 over Denon AVR-S640H

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-S640H supports 5.2-channels sound, but Marantz NR1710 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 AVR-S640H this value is 75/8 W/Ohm, and for the NR1710 it is 50/8 W/Ohm.

Audio features

After reviewing the audio features of each model, we can rate the AVR-S640H 6 out of 10, and the NR1710 - 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 NR1710.

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. Marantz NR1710 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-S640H scored 7, and Marantz NR1710 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, Denon AVR-S640H got 6 points, but Marantz NR1710 received 9 points.

Denon AVR-S640H is equipped with 5/1 HDMI inputs and outputs, and Marantz NR1710 has 8/1 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 Marantz NR1710.

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-S640H in the HDCP 2.2 version, and Marantz NR1710 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-S640H were rated 6 out of 10 against the 7 for the NR1710.

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 Marantz NR1710.

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-S640H got 5 points for the multichannel surround sound and Marantz NR1710 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. Marantz NR1710 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 NR1710.
