Axiom...

QS8
plus...dual SVS PCi 20-39

And I just got my Outlaw 990. I can't tell you how it compares to the Emotivas, but I can say that the center and surround channels on the 990 are MUCH clearer and enveloping than my B&K Ref 31. I haven't A/B compared the B&K and Outlaw yet but I know I always had problems with the center channel on the B&K and used to have to run it hot (+3-5dB). Now with the 990 I run it equal to the mains and the dialog is crisp and clear.

The Axioms seem to be a fantastic match with the Outlaw 990.
