i'm about to upgrade my LCR from my current cheap Philips FB975 setup to im thinking monitor 50's with a cs2. would like to get some opinions the way im thinking about placing them. also, i know i shouldn't even really ask this, because the difference will probably be night and day, but how much difference do you think the sound of the m50's/cs2 would be over the current philips i have? current system setup is listed in my sig. thanks.
