Is there a such too much power for speakers?

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. 

Most of the amps I really like are low in power.  This is the case with both solid state and tube gear.  I particularly like low-powered tube amps.  Of course, the speakers to match with such amps must be high in efficiency and must present a reasonably easy.  I also find that some high powered amps sound a bit lifeless if they are idling along at low output so it might be better to not go with really high powered amps if they are to be coupled to higher efficiency speakers/

There is also the possibility of high powered amps damaging a speaker because of a loud pop or other transient noise or someone accidentally cranking the volume. Speakers that are higher in efficiency tend to be capable of taking only modest levels of power before being damaged.

So far, my favorite 2 amps have been 45wpc & 35wpc. One SS(45wpc) & one tube @35wpc. The Tube amp replaced a 250wpc SS CJ 2500A. However, the speakers (Silverline) are 93.5db sensitivity. I don't know if that answers the question. But I definitely know that higher wattage does not equal better sound.
