Hey Jimmy,
I, too, have no experience with Dynaudio speakers. But, I have run across several folks who use speakers other than Axiom as their fronts and center, and use the QS series as their surrounds. Having the surrounds matched to the fronts and center, while preferable, isn't AS crucial as having the fronts and center matched. I'd be surprised if you couldn't get away with mixing the QS speakers with your Dynaudios. But, should it not work, it wouldn't cost you much, in return shipping, to return the Axioms as long as it's within the 30 day trial period.
