hmmm...
I think what is frustrating is that you did indeed accept no advice on here at all in regards to the speakers you purchased. I understand trying to use what you have, but having an 11.2 system of crappy speakers is not worth the hassle, nor is it fair to your ears. In all honesty I would return what you have purchased, get a much better receiver from Yamaha, Denon or Onkyo and heed some of the speakers advice on here. I would much rather listen to a good 3.1 system than an iffy 5 or 7.1 setup. I know your brother likes Sony, and believe me, there are many worse brands. But I just listened to a guy that cannot believe how good Bose is, and how when you get to their level you start talking about some really hq systems and it hard to find comparisons. I will never get back that 15 minutes of my life, never, ever.....ever.
