Second, the quality bass I used to have is now replaced with just huge boom. Undefined, overexaggerated and muddy bass, especially with music. My room now sounds like a circuit city demo room. I have changed the intellivolume to -10 as recommended but that didn't help at all. I have not changed anything at all except swapping the 886 for the 805, everything is same as before. So far I have only played a few songs but so far it is a huge step back in terms of sound quality vs. the 805 which led me to believe that I have either got a lemon or I missed something during setup. Any suggestions?
Do you have Dynamic EQ on? Many folks seem to find the bass much too heavy handed for music with it on, myself included. You can turn it off and still leave the MultiEQ engaged for basic room correction. After all, its just a fancy loudness control... turn it off if its not working for your source - you will not be discarding the core value of Audyssey. BTW, you can make that an easier task, or even automate the process for music sources, by adding the discrete Dynamic EQ IR codes to your universal remote, if you use one.
As far as the speaker distance settings, those only effect phase. While phase does effect imaging, its more in the vein of how focused vs. diffuse the imaging is, not the actual location the sound appears to be coming from. That is much more effected by the relative speaker level controls. Try tweaking the speaker levels rather than the distance controls.
Finally (just asking, not pointing fingers
)... you are comparing the 886 to an 805. Were you using the the 805 as a preamp with external amps or with internal amps? If external amps, are they the same as you are using with the 886? If they were not the same amps as you are using now, then that is another variable in the equation you are trying to solve.
