The 60-second rating is specs-man-ship, not actual headroom as it was originally defined.
In a class D amplifier heat is the main issue as often they don't have much for a heatsink. The idea is the output devices spend no time in the linear region so they don't make much heat. It works fine unless you play organ pedal tones at high volume- extended high power tones can heat up the output and possibly drain the supply.
