Many amp designers say amps tend to work at their most linearity at around 20% of their full rated output. As has previously been posted, volume increases require logarithmic power output. Having an additional 80% of total power output for headroom is prudent. Running out of power; can lead to clipping; clipping can lead to speaker damage.
Speaker sensitivity, room considerations and desired volume levels will ultimately determine how much power one needs.
There used to be an oft repeated audiophile general rule of thumb; "double the manufacturers minimum power recommendation".
