I have 2 systems 1-Marantz sr 7000 w/Def.tech. Procinemas in familyroom. 2-Yamaha RV496 w/energy take 5 in kids play/tv room. I'm planning to upgrade familyroom to Mirage om9 or om7.Also debating in getting Marantz sr7200 for family room.I'm unsure if ill need an amp for the mirages.I was planning that when i get the mirages and marantz to use the sr7000 in the kids room and take the yamaha and use the multiroom of sr7200 to run my outdoor speakers. What do you pros think would be my best bet. Should i get the sr7200,should i just get a 2 channel amp for the multiroom and possibly a 5 channel amp for the sr7000 and mirages if needed(will i need it?).I'm unsure what to do.Please bare with me since i'm a newbie. What do you guys suggest.By the way i'm presently running the outdoor speakers thru a niles switch box which i dont like doing. Thanks in advance.
