Pass labs poweramps

First l want to thank everyone for responding and l should not have said popping sounds actually it is clicking sounds l hear a few of then the unit stops. I have a trigger on it from my preamp so it stays in standby.

Popping is usually a sign of excess DC on the line
i experienced this recently with a tube amp .
get it checked out .
what model,  how old  is it.

I didnot read every response ,it went from popping to a clicking.
unless you know whatelse is in the chain   Impossible to give an accurate diagnosis.

Thanks for the info the is X260. 8 monoblocks
