I've never seen a diaphragm crinkle like that under normal operation.

The best way to measure this would be with a digital scope on a suitably slow sweep speed so you can catch the peak value of the transient. But this is not what's normally called DC offset. DC offset is typically present all the time. This is power down transient and is likely caused by the DC operating point of the Asgard becoming unstable as the power supply voltage falls. With such a beefy power supply you need big power supply caps which can store a lot of charge. Typical headphone amps can use much smaller capacitors so such transients are typically much less significant.
