According to the results of our review, Denon AVR-S650H received 6.2 points out of 10 possible, and Marantz SR7015 was rated 9.6 points. The release date of AVR-S650H is 2019, and SR7015 is 2020. And as a result of the review, it becomes clear that AVR-S650H is inferior in audio processing features to SR7015.
For the built-in amplifier, the devices received different marks - 6 and 9, respectively, on a 10-point scale.
The number of channels is equal to the number of possible connected speakers. The Denon AVR-S650H supports 5.2-channels sound, but Marantz SR7015 supports a 9.2-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 SR7015 this value is 125/8 W/Ohm, and for the AVR-S650H it is 75/8 W/Ohm.
|Stereo power (RMS), W/Ohm||75/8, 100/6||125/8, 165/6|
|Output impedance, Ohm||8, 6||8, 6|
|THD in stereo, %||0.08||0.05|
After reviewing the audio features of each model, we can rate the AVR-S650H 6 out of 10, and the SR7015 - 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 SR7015.
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 SR7015 can work with the main and additional set of speakers - and switch between them.

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-S650H were rated 6 out of 10 against the 10 for the SR7015.
With the 4K pass-through feature, the AV receiver sends "native" 4K signals to a 4K TV from a video source without any processing. The AVR-S650H works with the 4K/60Hz video, and the SR7015 has the 4K/120Hz.
The AV receiver passes "native" 8K signals from a video source to 8K TV without any encoding, with the 8k pass-through features. The 8K path-through is available on Marantz SR7015.
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 SR7015.

Denon AVR-S650H got 5 points for the multichannel surround sound and Marantz SR7015 got 10.
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 SR7015 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 SR7015.
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. Marantz SR7015 has Auro-3D on its feature list.
IMAX Enhanced is a licensing and certification program under which home theater devices deliver crisp 4K HDR pictures and powerful sound as it was designed by the IMAX engineers. The SR7015 licensed by IMAX.
