Why can I feel vibration when I touch my network switch or streamer?

I have a Silent Angel Bonn N8 switch powered by a Forester F1 linear power supply, which is attached to an Innuos Zen Mini Mk3 with a SSD, also powered by a linear power supply.  The N8 and Mini sit on top of their power supplies.

 

When I lightly touch the top of either the N8 or Mini, I can feel a slight vibration.  I am surprised by this because neither device has any moving parts that I know of.

 

Why does this vibration occur?  Is it inherent vibration of the electrical parts within the devices (e.g., resistors, capacitors)?

 

Would I be well-advised to avoid stacking the N8 and Mini on their power supplies?

 

Should I simply decrease my coffee intake?

Unless you keep your network gear under your pillow and it keeps you from sleeping, I'm not sure why having a network switch vibrate is of concern.

All of the replies are interesting and helpful. I should have added that I am new to the audiophile world.  My enjoyment of the gear and the wonderful sound of the music has stoked my enthusiasm to learn more.  Regardless of the vibration, the Innuos Zen Mini Mk3 sounds great, and the Silent Angel Bonn N8 made a nice improvement.  In my case, isoAcoustics Orea footers made no difference for the Innous gear, nor did the Silent Angel footers for the Bonn N8 and its power supply.  So, I come away from the discussion with little concern about the sound, and feeling enlightened with more knowledge.  Thanks all!
