After reviewing the audio features of each model, we can rate the RX-V383BL 5 out of 10, and the TX-SR494 - 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 TX-SR494.
Pure Direct mode feeds sound directly to the amplifier and bypasses any DSP processing. Only Onkyo TX-SR494 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.
