To get informed with the specs of the receivers, we suggest you read the Denon HEOS AVR and Yamaha RX-A870BL review. According to the results of our review, Denon HEOS AVR received 4.8 points out of 10 possible, and Yamaha RX-A870BL was rated 8.3 points. Both AV receivers were introduced in 2017. This review shows us that the RX-A870BL is a better choice as a home AV receiver than the HEOS AVR.
For the built-in amplifier, the devices received different marks - 6 and 8, respectively, on a 10-point scale.
The number of channels is equal to the number of possible connected speakers. The Denon HEOS AVR supports 5.1-channels sound, but Yamaha RX-A870BL 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 RX-A870BL this value is 100/8 W/Ohm, and for the HEOS AVR it is 50/8 W/Ohm.
|Stereo power (RMS), W/Ohm||50/8, 65/6||100/8|
|Output impedance, Ohm||8, 6||8|
|THD in stereo, %||0.05||0.06|
After reviewing the audio features of each model, we can rate the HEOS AVR 5 out of 10, and the RX-A870BL - 8.
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 RX-A870BL.
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.

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 HEOS AVR got 5 points, but Yamaha RX-A870BL received 9 points.
Denon HEOS AVR is equipped with 4/1 HDMI inputs and outputs, and Yamaha RX-A870BL has 8/2 HDMI inputs and outputs.
Connecting a vinyl player or phonograph is possible using a Phono input which is represented by mini-jack or RCA connectors. Only the RX-A870BL 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 HEOS AVR were rated 5 out of 10 against the 10 for the RX-A870BL.
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 on the Yamaha RX-A870BL.
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 Yamaha RX-A870BL.

Denon HEOS AVR got 5 points for the multichannel surround sound and Yamaha RX-A870BL 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. Yamaha RX-A870BL 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 RX-A870BL.
