My Mirage M5SI are at least 15 years old, still sound great but they are huge and my wife wants to redo our entertainment system and wants me to get a smaller speaker. My old Deon 5800 lost its ability to switch video plus it didn't have HDMI so i got the Denon AVR 3321CI but it couldn't drive my Mirage without shutting down. So i had to use my old parasound amp to drive the Mirage's. I figured it I went with the SVS ultra bookshelf I could just use the denon and clear up some space. I am not a fan of the 3321 it has issues with video but that is another story. Just curious if you guys think it's a good upgrade on speakers? Do I keep the Mirage or get the SVS ultras?
