It isn't correct to say "a high watt amp
WILL awaken, liven, or up the performance of speakers even at low listening levels". But if you said
CAN awaken… you'd be more correct.
This depends heavily on a speaker's sensitivity and impedance, as well as a speaker's ability to handle high power. How easy or difficult is it to drive them to loud levels? How much high power can a speaker handle before something, usually the voice coil, fails?
50 watts may be plenty for speaker X, but 200 watts may be needed for speaker Y. If a less powerful amp has juice left over as speaker responds to the loud but often very brief demands of the music, then a more powerful amp will not make a difference. But if the amp runs out of juice before the speaker responds, and if that speaker can handle higher power, then a more powerful amp can make a difference.
When an amp runs out of juice while trying to drive a speaker loud, it is said to go into clipping.

Amps and speakers run on alternating current (AC) signals. Where the sine waves in the figure are clipped off, the signal becomes direct current (DC). DC signals are not good for speakers, especially fragile tweeters.
I hope that explanation helps. To learn more about clipping in audio see this
