I am also sure I ran Audyssey right as I said earlier movies play fantastic.
As a side note, I have The Walking Dead from iTunes which is 2ch AAC and the bass is decent at -12. So maybe it is an issue with the FLAC and MP3 codec?
I use a low level "restorer" function on my denon 3311 to bring back some of the low end. This seemed to help a lot getting the bass back into the music, and isnt boomy or as an intense raise as something like dynamicEQ would do. Perhaps also your sub sets up differently when you are in 2ch stereo mode. I know on my AVR that there is a seperate place to adjust for 2 channel playback completely seperate from the audyssey and standard XO and adjustments menu.
For instance, I COULD set my receiver to not use a sub for music and to switch my L/R's to full range, but when I switch back to dolby or other multichannel modes, it switches the mains back to be LP'd at 80hz and the sub to come back on... There are other combinations that could contribute to not hearing as pronounced bass. I know this specific example above isnt what you are experiencing since when you turn the sun up, it gets louder. If the above were true, that wouldnt happen.
Im just saying perhaps peruse around your AVR menus to make sure you arent missing somthing in stereo mode.
