One other thing I have forgot to mention is that I like to bump up my center channel at least 2 dB's higher than my M60's. If I use the meter and calibrate using 75dB's or if I use the built in microphone option, it always places my center channel a few dB's below my mains. During movies it is hard to hear the dialog at lower levels. If I crank it up then the other speakers blow you out of the room. I think others have mentioned they like to bump up the center as well.
