First of all I need to put out the fact that I live in a mobile home currently and that this is my first home theater setup. I am purchasing a Sony 930E 65" or 55" depending on space and total cost. The plan is to go 5.0 or 5.1 using: Definitive Technology BP 9020 Towers, Definitive Technology SR-9040BP Rears, Definitive Technology CS-9040HD Center Haven't decided if I need a sub or not yet. I'm considering adding the atmo's add on speakers as well but not sure I would gain much currently due to lack of space and living in a mobile home. I'm not sure what receiver to go with just yet either. I'm open to recommendations from either Denon or Marantz. My main question would be what else I may want to consider adding to my purchase. I am getting speaker wire and 4k hdmi's from amazon. Surge protector is a Rocketfish 12 outlet model. I just joined up because this seems like a noob friendly forum and everyone seems really knowledgable. Can't wait to hear from everyone.
