Let's compare Denon AVRX4400H versus Denon HEOS AVR for an overview of all their pros and cons. According to the results of our review, Denon AVRX4400H received 9.2 points out of 10 possible, and Denon HEOS AVR was rated 4.8 points. Both AV receivers were introduced in 2017. And as a result of the comparison, AVRX4400H seems to be a better option for the role of a home theater center than HEOS AVR.
For the built-in amplifier, the devices received different marks - 9 and 6, respectively, on a 10-point scale.
The number of channels is equal to the number of possible connected speakers. The Denon AVRX4400H supports 9.2-channels sound, but Denon HEOS AVR supports a 5.1-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 AVRX4400H this value is 125/8 W/Ohm, and for the HEOS AVR it is 50/8 W/Ohm.
|Stereo power (RMS), W/Ohm||125/8, 165/6||50/8, 65/6|
|Output impedance, Ohm||8, 6||8, 6|
|THD in stereo, %||0.05||0.05|
After reviewing the audio features of each model, we can rate the AVRX4400H 9 out of 10, and the HEOS AVR - 5.
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 only on the AVRX4400H.
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 AVRX4400H 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 AVRX4400H got 10 points, but Denon HEOS AVR received 5 points.
Denon AVRX4400H is equipped with 8/3 HDMI inputs and outputs, and Denon HEOS AVR has 4/1 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 only on Denon AVRX4400H.
Connecting a vinyl player or phonograph is possible using a Phono input which is represented by mini-jack or RCA connectors. Only the AVRX4400H has a Phono interface.

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 AVRX4400H were rated 10 out of 10 against the 5 for the HEOS AVR.
HDR pass-through gives you the possibility to broadcast HDR content directly from source to TV without the processing of the receiver. HDR support is available only on the Denon AVRX4400H.
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 only with Denon AVRX4400H.

Denon AVRX4400H got 9 points for the multichannel surround sound and Denon HEOS AVR got 5.
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 AVRX4400H 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 AVRX4400H.
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. Only the Denon AVRX4400H has Auro-3D on its feature list.
