Why do you need so much power?

I have a basic question.  I have a set of Tannoys with 93dB sensitivity. I’m told that a 25 Wpc amp like the First Watt J2 can power it just fine. (I don’t crank it to 11.). Someone also suggested an Emotiva amp with 500W RMS. 

So my question. Assuming you have a good set of speakers that are efficient (>90) and you don’t crank it till it’s clipping, then do you ever need such power as the Emotiva?  Thanks!

Robert Harley answered your question years ago:"If the first watt isn't any good, why would you want 200 more of them?"
Yeah well, that's also a load of ****
The first couple of watts in any a/b amp are usually the better sounding Class-A biased ones, naturally the rest in Class-B are not as good, as they have a bit of crossover distortion in them

I'd like to know who the fool was that said that.
