Amplifiers

For the built-in amplifier, the devices received different marks - 8 and 10, respectively, on a 10-point scale.

The number of channels is equal to the number of possible connected speakers. The Denon AVRS730H supports 7.2-channels sound, but Denon AVR-X6400H supports a 11.2-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-X6400H this value is 140/8 W/Ohm, and for the AVRS730H it is 75/8 W/Ohm.

Audio features

After reviewing the audio features of each model, we can rate the AVRS730H 6 out of 10, and the AVR-X6400H - 10.

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 AVR-X6400H.

Pure Direct mode feeds sound directly to the amplifier and bypasses any DSP processing. Only Denon AVR-X6400H 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.

Speaker A/B switching allows you to change between the main and sub speaker set. Denon AVR-X6400H can work with the main and additional set of speakers - and switch between them.

Connectivity

The connectivity of competitors in our comparison is equal and was rated 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 Denon AVRS730H.

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 AVRS730H got 6 points, but Denon AVR-X6400H received 10 points.

Denon AVRS730H is equipped with 6/1 HDMI inputs and outputs, and Denon AVR-X6400H has 8/3 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-X6400H.

Connecting a vinyl player or phonograph is possible using a Phono input which is represented by mini-jack or RCA connectors. Only the AVR-X6400H 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 AVRS730H were rated 7 out of 10 against the 9 for the AVR-X6400H.

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 Denon AVR-X6400H.

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 AVRS730H got 7 points for the multichannel surround sound and Denon AVR-X6400H got 9.

Auro 3D gives a bit more versatility than Dolby Atmos or DTS:X and provides a hemispherical sound and enables a receiver to produce 3D sound stages. Denon AVR-X6400H has Auro-3D on its feature list.
