Watts and power

Can somebody break it down in layman's terms for me? Why is it that sometimes an amp that has a high watt rating (like, say, a lot of class D amps do) don't seem to always have the balls that much lower rated A or AB amps do? I have heard some people say, "It's not the watts, it's the power supply." Are they talking about big honkin' toroidal transformers? I know opinions vary on a speaker like, say, Magnepans - Maggies love power, right? A lot of people caution against using class D amps to drive them and then will turn around and say that a receiver like the Outlaw RR2160 (rated at 110 watts into 8 ohms) drives Maggies really well! I'm not really asking about differences between Class D, A, or AB so much as I am asking about how can you tell the POWER an amp has from the specs?

Oh come on Clearthink. You can do better than that. I am not sure that rant is even worthy of inclusion in my book, "Clearthink's Practical book of Impractical Rants". I have come to expect much more of you.

JerryBJ,

No to belabor a point, but someone that accuses others of trolling I understand has even sent private messages to people asking them to report threads they did not like.

In general if an amp can double down (100wats @ 8 ohms, 200 @ 4, 400 @ 2) that means it has a well made power supply and can supply the necessary current.   It also usually means there is usually good power reserves to cover transient peaks.
The only reason all amps don't all double down is because the designer got cheap and the power supply can't keep up.

You guys ever read Greek mythology? I feel a little like the goddess Eris throwing the apple of discord into the feast of the gods. 

All I thought I was doing was asking a simple question. Honest.

Safety behind a keyboard. Seems what some are doing.
Their true personality appears.
You can't treat your family like this. Or your friends. Workmates wouldn't put up with it either.
And it ruins the forum.
