After receiving my 990 last week, and what I thought was careful setup, I found the sound of my system lacking in bass and bright. I read several posts from others stating they thought the unit bright sounding so I chalked it up to a characteristic of the processor. A couple of days ago it ocurred to me that the low pass crossover of my subwoofer was still engaged so I disabled it allowing just the 990 to handle the crossover. Bass reappeared and the sense of brightness diminished (the 990 breaking in helped also). I attribute this to the phase shift reusulting from deactivating the sub crossover which minimized cancellation with the bass from my main speakers (Apogee dipoles).

As a possible future option for the 990 I would like to see a remote controllable sub phase adjustment to help easily determine the correct phase relationship with the main speakers.
