Does your Phantom (Gold) have a hum/buzz?

If I press the button on the back of the Phantom for about 8 seconds, the woofers makes a sound and the annoying noise disappears on my Golds. Seems like it's a way to turn the speakers off. I thought the culprit was the PSU, but if the noise stops when pressing the button, the WiFi module is more likely to blame? The speakers are missing in Spark after the 8 seconds8 push procedure.

It is actually about 5 seconds and it does switch off your phantoms. So, all modules are not working, so no noise.

My point was; if the PSU was the culprit, the noise would still be there after turning off the speakers. Hence something else is to blame.

Usually there are two circuits in the devices, one for low-power operation (like turning on when the button is pressed, or activation on the ethernet signal, etc) and another for high-power operations. So I still think it's the power.

What worries me even more is that Devialet says that the Expert noise is normal for the following reasons (https://help.devialet.com/hc/en-us/articles/203427171): 

Although there are no moving parts inside a Devialet, you may hear in some cases an extremely soft noise in stand-by. There is absolutely nothing to worry about. It is caused by the vibration of some ferrite elements in the power supply. The level of this extremely low noise varies from unit to unit. Again, there is absolutely nothing to worry about.

I am still worried though since it ruins my musical experience. Once I had a buzzing Emotiva mono amplifier and they agreed to change it, readily admitting that it's their mistake.
