I have an Axiom 5.1 set up and an Energy RC 7.1 set up, very similar to what you will have with the addition of 2 RC-10's for rear surrounds. while I feel that the Axioms have a better bang for buck value, I prefer my Energy's overall. the RC-R is a very good speaker, if you can get the second one, I would stay with it over the QS-8's.
