Ya I understand what you're asking. I like all channel stereo or multiple channel stereo as a sound mode which are extra sound modes on most AVR's. Not sure what your denon has for extra sounds modes but there should be a button on the remote that says auto, sound modes. so forth that would step through those. They could be called dolby surround, pure, direct, avr's all name them different. If you have the manual to that avr it should say what the extra sound modes do to a 2ch source such as the 2ch music you're playing. Happy playing with the sounds modes. Don't pull your hair out...... Let if fall out naturally.
