I have an upstairs attic that has been converted into two rooms...one is a playroom for the kiddo (soon to be kiddos), and the other is a 400-500 square foot media room. I currently have a 100" silver ticket screen and a 1080p Viewsonic projector hooked up to an old Onkyo s3500 5.1 system. I know the Onkyo is a good starter system (I'm actually pretty impressed with it) but I'm ready to upgrade. I'm thinking of buying an Onkyo 7.1 receiver and hooking it up to Pioneer Andrew Jones Atmos speakers. I'm just wondering if the atmos would be overkill. The other option is a 5.1 receiver with Klipsch speakers. I'm just not sure what to do next and would be grateful for any advice. Price is definitely a factor. The screen and front speakers are about 12' from viewing, and the back speakers are about 6-7' from viewing. Ceilings are probably 7-8' high. I would appreciate any help. I was thinking the next step would be a new receiver, then I could start systematically replacing speakers.
