Bruce,

I miss stated my Yamaha used as a pre/pro, it is in fact a V750 7.1 receiver.

I not sure what you mean by 100%, but calibrated to 75db at 0 volume, movies or 7 channel stereo is too damn loud for me. I have NHT speakers which love power, they can take what the 755 and two M200s put out, but my ears cannot. My normal listening level is -20 to -15 volume.
