Best way to measure an Amp's power capability


Hello Everyone, 
As we all know not all watts are created equally. A 1,000 watt amp from brand A can be trounced by a 100 watt brand B amp. 

So what is the best way of telling if an amp is high current just by reading the specs or may be by looking at the inside of an amp?

What should one look for?

Thanks in advance!

I'm certainly not an expert on this subject. I do have some difficult speakers, Revel Salon 2's (85 db). I am driving them with McIntosh 601 monoblocks. I am using the 4 ohm taps to better match the impedance of the speakers. I can drive these speakers at loud listening levels for long periods of time and my amps will only be warm to the touch. My dealer told me these would be a good choice for the Salons because of the autoformers. Not saying there aren't many other good amps out there that would do just as good. However the point others are making in this discussion are correct. Don't just play the numbers, you need to match the components.
