Along with the growing popularity of custom home theater builds, the comparison of Sony STR-DH790 and Onkyo TX-SR383 takes place. According to the results of our review, Sony STR-DH790 received 5.3 points out of 10 possible, and Onkyo TX-SR383 was rated 4.8 points. Both AV receivers were introduced in 2018. Based on the data on the characteristics and features of both models, we can conclude that STR-DH790 has better performance than TX-SR383.
For the built-in amplifier, the models have rated 7 points out of 10.
The number of channels is equal to the number of possible connected speakers. Both receivers can handle the 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 TX-SR383 this value is 135/6 W/Ohm, and for the STR-DH790 it is 90/6 W/Ohm.
|Stereo power (RMS), W/Ohm||90/6||100/8, 135/6|
|Output impedance, Ohm||6||8, 6|
|THD in stereo, %||0.09||0.09|
After reviewing the audio features of each model, we can rate the STR-DH790 8 out of 10, and the TX-SR383 - 6.
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 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.

Sony STR-DH790 got 7 points for the multichannel surround sound and Onkyo TX-SR383 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. Sony STR-DH790 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 STR-DH790.
