I was a bit surprised when I got my new 770amp and then adjusted my calibration. All my speakers had to be adjusted UPWARDS from my receiver inputs instead of what I predicted downwards.

My thoughts was that since I more than doubled the power to my system with the amp, that my calibration adjustments would have less power needed to my speakers. However it was just the opposite.

Is this common? Does anyone know why my thinking was incorrect on my calibration?
