To get informed with the specs of the receivers, we suggest you read the Denon AVR-S640H and Marantz NR1710 review. According to the results of our review, Denon AVR-S640H received 6.2 points out of 10 possible, and Marantz NR1710 was rated 8.3 points. The release date of AVR-S640H is 2018, and NR1710 is 2019. This review shows us that the NR1710 is a better choice as a home AV receiver than the AVR-S640H.
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.
|Stereo power (RMS), W/Ohm||75/8, 100/6||50/8, 70/6|
|Output impedance, Ohm||8, 6||8, 6|
|THD in stereo, %||0.08||0.08|
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.

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.

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.
