I am thinking that I will actually route the preouts of the Yamaha to the 7.1 input of the 990 as I have heard the 990's 7.1 is very clean.

As I have lived with the Yammy for ~ a year now, I should be able to tell if there is any difference in its character as a result of doing so.
I was also lurking around over at AVS forum today and found the following link pertaining to Outlaw:
