Let's compare Onkyo TX-SR383 versus Denon HEOS AVR for an overview of all their pros and cons. We estimated the compared receivers and both received a 4.8 out of 10 points. The release date of TX-SR383 is 2018, and HEOS AVR is 2017.
For the built-in amplifier, the devices received different marks - 7 and 6, respectively, on a 10-point scale.
The number of channels is equal to the number of possible connected speakers. The Onkyo TX-SR383 supports 7.2-channels sound, but Denon HEOS AVR supports a 5.1-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 100/8 W/Ohm, and for the HEOS AVR it is 50/8 W/Ohm.
|Stereo power (RMS), W/Ohm||100/8, 135/6||50/8, 65/6|
|Output impedance, Ohm||8, 6||8, 6|
|THD in stereo, %||0.09||0.05|
After reviewing the audio features of each model, we can rate the TX-SR383 6 out of 10, and the HEOS AVR - 5.
Pure Direct mode feeds sound directly to the amplifier and bypasses any DSP processing. Only Denon HEOS AVR 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.
