An overview of Denon HEOS AVR and Yamaha RX-V683BL will help us understand the many features that the devices are equipped with. According to the results of our review, Denon HEOS AVR received 4.8 points out of 10 possible, and Yamaha RX-V683BL was rated 7.1 points. Both AV receivers were introduced in 2017. And as a result of the review, it becomes clear that HEOS AVR is inferior in audio processing features to RX-V683BL.
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 HEOS AVR supports 5.1-channels sound, but Yamaha RX-V683BL 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-V683BL this value is 90/8 W/Ohm, and for the HEOS AVR it is 50/8 W/Ohm.
|Stereo power (RMS), W/Ohm||50/8, 65/6||90/8, 150/4|
|Output impedance, Ohm||8, 6||8, 4|
|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-V683BL - 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-V683BL.
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.
