Use pink noise disc to warm up stereo

I I thought we had already discussed the warm-up vs. no warm-up topic ad nuseam. Technically speaking, if I understand it correctly, the main and possibly only difference between pink noise and “regular” music is all frequencies are at or near identical amplitude. Maybe this implies a uniform voltage or current is “seen” by the components in the path of signal thus causing a different behavior. Perhaps  someone with an in-depth understanding of how electronic components react to constant vs. varying voltage/current can chime in.
Interesting find nonetheless. 

There are also a number of free phone/tablet apps that generate pink noise if you have a Bluetooth capable streaming device. Handy for speaker placement as well.
