Hi all. My system is currently Polks. RTi8 fronts, CSi5 centre, FXi3 surround powered by Denon 3805. I have been thinking about going with Axiom. M60ti or M80ti fronts, VP150 centre and QS8 surround.

Would the Axiom be considered an upgradge? I know they are more efficient, but the centre and surrounds are 6ohm and if I go with M80's it 4ohm(I could add Outlaw m-blocks).
