Is there a such too much power for speakers?

DTC,
totally agree with you, and I think gdnrbob describes the reason for lots of power well, for us  non-techies.

Might get some suggestions of good amps that match your speakers from those who have heard or own them  if we knew what speakers you're talking about. 

Speaking of NASA, they put up a satellite many years ago with the goal of measuring very fine variations of the background radiation that permeates the universe. One interesting little tidbit that I recall is that the radiation had a frequency of several hundred or thousands of light years, now frozen for all eternity. Someone was playing some monstrously large bass back in the mists of time.

sorry for going off topic.

The thing is, I listen from low to mid Volume level around late nights.

>>>Light years is a distance not a frequency but I know what you mean. Good point as cosmic background radiation is Exhibit A for the Big Bang.
