First, I assume that this click you hear does not occur when you are not using the power line adapters (PLA). This probably means the PLA are the source of the problem. You mentioned you swapped some of them to rule out a defective PLA. These PLAs work by transmitting a frequency into the house wiring and then receiving it on the other end, so they introduce a source of line noise. I am going to guess to avoid audible interference they generally use high frequencies outside human hearing. Which brings us back to why are you hearing this?
My first though is they are defective. My second thought is maybe they are simply poor design. Trying a different brand may test this theory. My third thought since you only hear the click is when there is no audio source is that it is a faint harmonic from the PLA. Your amp should filter the power source to clean up power line noise. But what if the noise is coming through the audio signals? Disconnect the audio input to the amp to see if it goes away. If yes, you have a harder problem to solve. If it is the power source then you should be able to filter the noise by using capacitors or a choke. Look up filtering for ham radio equipment or contact a local club. I know this doesn't answer your question, but I hope it may point you in the right direction.
