Some people use powerful amplifiers for increased headroom, which comes in handy with material high in dynamic range and/or low in compression. One hit of a kettle drum might require a great deal of power to reproduce but it certainly won't heat the amplifier up enough to cause its fan to run. I had a Sansui G22000, and not once did I ever see its fan come on, and I've definitely driven it to its limits. Speaking of the Sansui, I'd love to see how something like that would perform in these tests, and I'm curious how something this old would compare to a more modern amp in sound quality, even something like a Behringer A800. Some of the Sansui's specs are 220 watts per channel into 8 ohms, both channels driven, from 5-20,000Hz with 0.009% THD. It even lists the frequency response as DC to 300,000Hz at +0/-3dB. Here's the brochure.

If one buys a high powered PA amp whose fan never turns on, could we say that they're not being worked hard enough? And if they're not working it hard enough, then why did they need a PA amp with all that power in the first place?...
