 I have a simple  question about my fiio e09k amp. Do I unplug the headphones before or after I turn the amp off ? I cant seem to find an answer online and when I turn off my grado sr80 headphones I hear a small (not very loud) pop in the left can and im just not sure if this is ok or if I should turn volume down to 0 unplug and then turn off amp. The reason I really want to know is because I have ordered a more expensive set of headphones and do not want to damage them.

Shouldn't be an issue, but its generally safe to plug/unplug headphones with the device off.
