Eliminating hum


I have read in the forum that using cheater plugs is one way of eliminating hum through speakers. My question is which components should have cheater plugs. Amp, preamp, DAC, or CD player?

Thanks for the info. One more question. If there is a hum generated from a ground loop would it be there say at the end of a song or between tracks when listening to the CDP?
