I have had my M60's, VP150 and and QS8's for two years and am very satisfied. (Sub is SVS) My receiver is a Denon 3805 and DVD/CD player is the Denon 3910. Again, very satisfied with the system. I've been reading where a separate amp for the fronts sometimes would help. Any comments? Everyone says the M60's are easy 8 Ohm speakers to drive. Would I hear a difference with a separte amp for the fronts?
