Is there a such too much power for speakers?


How do I know the amp I’m looking to buy is beautifully enough power for my speakers?
what will happen when the power amp is (way) over or too much power for the speakers?
My Local dealer quoted, “there aren’t limits on power amp, (but my budget that is). The more, the better, they added”
Their suggested highest amplifications are in $75k range (my speakers are in $20k range)
Please help.

fundsgone62 - Sonus Faber Cremonas are hard speakers to drive. I agree they require a lot of power (actually a lot of current) to drive them due to their phase angle at low frequencies. I tried multiple amps on them and ended up with Mark Levinson 432 with 400 watts per channel. However, other speakers can be much easier to drive. It depends so much on the design of the speakers.

You are more likely to damage speakers with an underpowered amp than an overpowered amp.

And yes: lose that dealer.

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.
