I've noticed a click through the speakers whenever my oil burner turned on or off; today I noticed it when a fan in the house was turned off. I live in a split level home- the burner is downstairs, almost certainly on its own circuit, the fan is upstairs. My system is on the main level, in the middle. I sincerely doubt they are all on the same circuit.
The offending click is low in volume, nothing that would damage anything. It is only noticeable when the volume is low, or nothing is playing but the stereo is turned on. At a normal or loud volume with music playing the click cannot be heard.
Any thoughts?
Thank you.

  James the circuit may be on the side leg of your panel. Do not assume your Boiler is on a dedicated line. Do you know an Electrician ? A dedicated line would eliminate any issue like that.

The line voltage is varying, either rising or dropping for possible reasons, including an inductive kick". When the power is suddenly turned off, an inductor's magnetic field collapses, causing a voltage spike. There is usually nothing to fully absorb the spike voltage.

Insufficient power supply filtering is the cause, especially affecting the low level components. Such conditions allow the rectifier tube (if used), power transformer etc to affect the sonic quality of the component as well. As you mentioned, it won't harm a component, just noticeable.
