Down to my last question, hopefully... I am getting the 60's, 150, QS8's. I think I will have the option to do 7.1. If I do I was think to go with M2's for the rear. Should I do this or stick to 4 QS8's? If really debating getting the 500 instead of the 350 as well. If I go with the M2's then it would be in an easier price range for my wife. Thanks for your help as always.
