60 sec rating IS heat related. Even figuring 83% plug to speaker efficiency, that leaves something around 75 watts of heat.....quite a bit....A human emits about 100 watts worth, if I'm remembering correctly.

For the Big kilowatt module? Time limit is 30 seconds.

Both per B&O datasheets.

Heat is, of course, the enemy. Which is why some people will do a first pass judgement of amplifier quality by using a scale. PS and Heatsink, of course.

I don't know that my amp has a capacitor larger than my thumb and therefore doesn't store enough energy to drain. Being a smps, the tranformer is also small, gaining from the high frequency at which it operates.

One day I'll put my Killawatt meter on the amp, crank it up and see how much juice it DOES draw, when I'm pushing it. At the same time, I'll look for PowerFactor which is something neither of us has touched upon as yet. I don't know if that is germain to the headroom issue, however.
