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

Electricity establishes vibration on all circuits, capacitors, transformers, transistors, resistors, and parts. You cannot stop vibrations from taking place if using electricity or man-made power sources. 

Sound is Vibration. You will never destroy, isolate, decouple, or terminate vibrations, particularly in a vibrating musical environment. Once you get past that reality, the fears of vibration become less of a concern as the initial vibrations provide the dynamics and harmonic layers we seek as listeners. 

In audio, vibration has become more of a fear than understanding. You are in a musical environment where sound is present. The speakers vibrate, electronics, equipment racking, structural angles and surfaces, and everything else, including the room develop resonance caused by vibrations. 

Resonance clogs all signal pathways such as electrical, electro-mechanical, and acoustic. Mechanical grounding establishes a path for resonance to evacuate the equipment to Earth’s ground in real-time. Equipment Operational Efficiency is the result. Effortless operation, volume increases, and increased musical qualities are easily heard when operational efficiency is presented.

+1 @allanblissett   I have my switch and modem sitting on a Townshend platform, with their power supplies neatly tucked underneath.

You should have the mini isoacoustics to separate and absorb the vibration which  has internal parts that  have micro vibration at certain frequencies .

the stock feet are NG  these mini feet by iso acoustic work very well.

I think the vibration issues some are referring to are micro vibrations which are controlled with different equipment footers spikes, isoacoustics etc. I’ve never felt micro vibrations. Anytime I have felt vibrations was with older vintage equipment and it was a grounding issue. 

It is probably a good idea to separate the power supplies from the components. Try separating them all and see if you can detect which one is vibrating. If both linear power supplies are vibrating, it might indicate you have some dirty power issues further up the chain.
