Thanks for the quick response. So right now the Onkyo defaults to Multichannel-(This mode is for use with PCM multichannel sources). Should I set it to default on the Onkyo to either of the two below for best sound reproduction.
Pure Audio In this mode, the display and video circuitry are turned off, minimizing possible noise sources for the ultimate in high-fidelity reproduction. (As the video circuitry is turned off, only video signals input through HDMI IN can be output.)
Direct In this mode, audio from the input source is output directly with minimal processing, providing high-fidelity reproduction. All of the source’s audio channels are output as they are.
