Well Gonk, I made the change and was sadly disappointed. Bypassing the LowPass Filter in ML Descent and allowing the 990 to manage the bass was not pleasant. Now I'm not saying the 990's bass mgmt failed because I still haven't done the update :-( I know, shame on me but will doing the update really make a difference in performance or will it just provide more controlled mgmt?

After making the change, it was now apparent the sub was located in the right corner of my theater, it lost its quickness and suddenly became boomy. And increasing the level made it worse .....it sounded like my 1990 Kenwood rack system....don't mean to offend anyone. Bottom line, it wasn't good at all. Needless to say, I changed it back to allow the ML Sub to manage the bass and like that, I had my system back. Woohoo!!!

So school is open...besides yelling at me for not doing the update, what else should I do?
