Finally my 990 firmware upgrade is completed and working great. I was pretty happy with my 990 before the upgrade and now although the upgrade features were small changes but it feels like getting new piece of equipment. Maybe my "upgraditis" will be tame little longer with 990's future firmware/software as well. The only thing I didn't like about from this firmware upgrade is the sub's trim level goes "wild" after certain level trimming (-13 dbs???). If the other member didn't mention about this bug, I am pretty sure that I thought my sub driver was fried. Anyway, overall I am satisfied with the 990's recent firmware upgrade.
