I dont get it the EP500 should still be able to blow a $400 computer system out of the water. I dont really notice it musically but I do for movies. The thing is I asked axiom if I would notice it musically if I upgraded from the EP175 to the EP500 and of coarse they said oh ya you will get a big peformance boost well I still dont notice it musically. And unless I turn the volume way up I hardly hear it at all even if I am right next to it the driver is hardly even moving unless the volume is past 12o clock. I have played everything DVDs, CDs and sacds. Movies sound great though the M22s are very midrange oriented so they are perfect for that. So either I am going deaf or I dont know but once my new center gets here a pro is coming out to configure this I am sick of wondering what I am doing wrong.
