Many amplifiers have a really annoying mechanical transformer hum (emitted from the transformer itself), especially those with toroidal (circular) transformers.
You can hear it when you place your ear close or next to the chassis.
This is usually caused by a small amount of DC voltage in the mains which makes its way through to the mains transformer, it will become ‘saturated’ and start to hum like a trooper.


All the benefits of cutting out annoying hum with no drawbacks.
Just deploy at each component. Remember that best practice is to always keep at least one direct power cable connection.
