i was wanting to upgrade my front sound stage from the fr52II's and rc52 that i currently have....and goin to the rp280f and rp450c...having said that, ill then be using 4 rf52II's as my rear surrounds....by doing that, opinions on if the new front setup would drown out my rear surrounds??? also, is there a better reciever to match with klipsch other than yamaha? i kinda like the yamahas, bur am willing to try something different
