Hello everyone, I may buy some McIntosh LS360 Loudspeakers to replace my Klipsch RF5. I currently own an Onkyo M5590 as a poweramp. I was wondering if it is powerfull enough for those speakers. My room is 215 square feet right now but I am going to change the room soon or later and the next room should be about twice as big. What do you think about all of that ?
