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?

audiozenology"You make many claims about amplifier performance that are not founded and would not be made by someone with a somewhat deep understanding of amplifier topologies and what drives their performance limitations."


You are really taking you’re newly discovered moral authority, obligations, and superiority to new heights, achieving a position of enlightened wisdom to dispense to the masses at you’re sole determination!
audiozenology"amplifier power tests, right or wrong are made into constant resistance loads"

This is true of course when amateurs, hobbyists, and inexperienced users conduct such tests but when performed by experts, engineers, and designers a much more thorough, complete, and extensive composition of tests is undertaken to accurately assess how a Music Reproduction System component will perform in real-world conditions by the end user.
audiozenology"if you post erroneous information that you can’t back up, people like me are quite warranted, perhaps even morally obligated to call it out."


The claim to heeding, following, and possessing a moral obligation certainly places you in a realm far above, beyond, and superior to many in this group and makes me wonder if you’ll be citing the bible next to explain, justify, and defend you’re mistaken, confused, scientifically absurd and laughable technical claims that are rooted in your incomplete, inaccurate, and ignorant grasp of elemental theory. I am still laughing over that convoluted and twisted "argument" you asserted regarding fuses as I recall that completely and totally overlooked induction as a basic electric principal you are "too funny" as Americans would say, so you’re superior "morals" and integrity can’t save you from embarassment but might make you feel better, smarter, and justified because of you're superior character and spiritual "enlightenment."
audiozenology"someone could build a Class D amp that can put 1500 watts into 2 ohms and sell it for <$400??  The benefits of modern manufacturing and a high volume sourcing chain, not to mention a lower margin market"

And the result,  of such "modern manufacturing" is a product that sounds awful but hey it's a "lower margin market" so that is to be anticipated and expected.

"
I do know for a fact it puts out 75% more power into 2 ohms than it does into 4 ohms."

That is a very interesting statement, assertion, and claim how do you know this to be true? This is like you're other pronouncements where you state something as 'fact" but offer no proof, documentation, or data except sometimes a link to a "source" that you Googled.
