I ran audessey with my m80'sd and wasn't terribly happy with the results. I changed the setting on my sub and re-ran it.... I had adjusted some of the channels after the audessey set up (fine tuned things with my SPl meter) and for some reason audessey just kept reverting to the old settings.

Acouple of weeks ago I did a hard reset and manually adjusted everything without ever running audessey. So far I like things much better without it...
