I have polk r series speakers r50 for the fronts and r30 for rears and a csi25 as my center. I was looking at the yamaha rx-v557 or the sony line but from reviews i have steered away from the sony de line. But does anyone now about the yamaha rx-v line or is there htr line any good? Any help would help out so that i can steer my wife in the right direction for christmas . Any other suggestions would be great help as well. I would like to stay around 300-350 or lower range due to the fact that my wife is doing the buying.
