While chatting with @sbnx, he suggested separating power supply chassis and audio chassis into separate racks. I'm curious if anyone has done this experiment?
It is known that power transformers can physically vibrate and hum, this could potentially generate vibrations that get transferred to the rack and other components. As a thought experiment, separating the power supplies chassis of all two chassis component into their own rack could isolate the audio chassis further from these vibrations. On the other hand, it's conceivable that each power supply unit has its own resonance and vibration characteristics where if several different power supply units were to be put on the same rack, the vibration patterns could interfere with each other, and spreading them out across different racks are actually better.
Looking for any practical experience in the matter or actual physics insights.
