According to the results of our review, Yamaha RX-V385BL received 4.7 points out of 10 possible, and Sony STR-DH790 was rated 5.3 points. Both AV receivers were introduced in 2018. After comparison, it will become clear that among these two devices, the STR-DH790 is more suitable for the role of the heart of home theater system.
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 Yamaha RX-V385BL supports 5.1-channels sound, but Sony STR-DH790 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-V385BL this value is 145/6 W/Ohm, and for the STR-DH790 it is 90/6 W/Ohm.
|Stereo power (RMS), W/Ohm||70/8, 145/6||90/6|
|Output impedance, Ohm||8, 6||6|

After reviewing the audio features of each model, we can rate the RX-V385BL 5 out of 10, and the STR-DH790 - 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 STR-DH790.
Pure Direct mode feeds sound directly to the amplifier and bypasses any DSP processing. Only Sony STR-DH790 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. Sony STR-DH790 can work with the main and additional set of speakers - and switch between them.
