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!

Depends what you are trying to do. If you are trying to get evicted, you'll need big power to make the windows rattle. After years of hi-power amps I make do with 25 and 50 watt amps now.  
(I don’t crank it).

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

Tannoys and Emotiva, just doesn't slide off my tongue.

The guy on the other thread didn't like Pass and Klipsch.

Geeez..

Pass and Tannoy, what could be better. A valve amp if that is your cup of tea. It would be mine. I like Tannoys, not suppose to blast..
