I am using a Denon AVR 5805 receiver with

Axiom:
2x M80 Front Speakers
6x QS8 Surrounds
1x VP150 center
1x Subwoofer EP500

It is configured for 9.1 surround. The system sounds great as it is, but is there some recommended settings that I should set in this receiver to really take advantage of these axiom speakers?
