I just purchased a yamaha rxv-440 receiver and some boston vr-950's. These are absolutly wonderful speakers and those will be my mains. Now this is mostly a 2 channel system I will proably do 60% tv 30% music and 10% movies. Now I also have a set of cheap sony towers that I havnt even heard yet. They were free from my brother. Would those do ok as surrounds? Also I got a gift certificate for amazon.com for x-mas would it be a bad idea to get an infinity primus center channel or a JBL center channel? Or should I just wait till I can get the boston stuff? Thanks for the help.
