Ok, I will start with what I have in my HT... Samsung LN40a550 LCD Onkyo TXsr705 Polk monitor 70 mains Polk CS2 center Polk OWM3 surrounds Sony BDPs350 bluray Velodyne VRP1200 and VRP1000 subs My biggest problem is limited speaker placement. With the wifey I can't have speakers and subs lying all over the living room. I don't have a assigned room for my HT so I have to make due until we find a new house. My idea is once I have the new designed area for HT I will add another pair of OWM3's for 7.1 and get a SVS pb13 Ultra. What I need to know is, with my setup-to-be what kind of amp would I need to compliment my system? I've heard that a 3 channel amp will do what I need because it will take the power I was using to push the mains and the center and give that power to the surrounds thus not needing a 5-7 channel amp. Is this my best bet? with the Onk 705 do I really need more power to the mains and center? Right now i have my Velodynes stacked behind my entertainment center in a corner. This is my only way of hiding them. I will try and add a picture so it might help in knowing what I might need to help me. Thanks!
