Define "oomph". When I think "oomph" its usually related to the sub.

But, I can assure you I have the model below in that receiver lineup and I'm not complaining about "oomph". I have the HSU STF3 though.

Proper setup will make a world of difference. Plus, the Axioms don't throw any muddyness at you which, if you are used to, will sound kinda "oomphy".
