I have a PS3 that i use for games and BluRay. I also recently bought a Sony 810. My speakers however are garbage. I would like to upgrade them, but in order to upgrade to something decent I would have to get them a bit at a time. So if I were to buy 1 speaker (or a pair) should I get the fronts or a center? I would probably get the other matching ones in 4-6 months or so, followed by the rears down the line. Also, is this a bad idea?
