I think the most important thing about those articles is that the 100W per channel is a marketer's concoction; audiophiles the world over live with tube amps that put out 10 or 20 watts per channel; one of the best sounding amps I've heard in recent times was a Tripath powered Charlize putting out only 10W at 4Ω. Power is overrated (pun intended) sometimes

and besides, is there such a thing as true RMS watts?

also, I read recently on TI that they only need to test for 1/8th peak power draw to be certified for a power consumption rating; so if an amp can draw 100W per channel peak, it can be rated as 12.5W per channel active power consumption; it does make sense in a way because there is never a program (music or movies) that will draw 100W in all channels all the time.

All this averaging out helps the marketing people stretch the power output rating
