They ever a showman Bob Carvar did a video once showed the power required to reproduce the sound of a pair of scissors doing one big snip. I think it was a short transient of 1,000 watts. Anything less clipped.
But that is the point of massive power… not in plying loud but delivering enormous current for short durations so not to compress the music. I have usually owned amps of twice the maximum power handling capability of my speakers. They always sounded better because of it. Typically with a real high current amp you have to turn the volume up less to sound satisfying.
