So I've been working to put together a system for my room with speakers I've just had laying around not really being used. I've got a set of Sony SS-CHPX9's and a set of Acoustic Monitor db IV's (I've heard the db IVs are white van speakers but I've been testing them with an old receiver and I think for my purpose, a dorm room, should do alright). The Sony's are maxed at 75w and the IVs are rated at 125w. I've been trying to find a decent receiver For around $150-200. I've come across plenty of receivers but I'm not exactly sure about pulling the good from the bad. I'm not sure whether I should consider a 5.1 system or not. Also any advice on which set should sound better in the front vs the back would be appreciated. Thank you
