I'm not too proud to miss an opportunity to beat a dead horse, so...

Give the 990 another shot. You might have an issue with the setup.

I've got a 950, 990, and AVM20 in my room with the interconnects wired through switches for quick A/B/C comparisons and to say that the 990 isn't in the same league as Anthem as far as audio quality goes just isn't correct. I can tell them apart in a blind test, but not 100% of the time. In my setup, the 990 sounds closer than you think to the Anthem. (But the Anthem's setup/bass management/software is definitely a step forward).
