Hi, one of my D200's made like a popping/crackling/clicking sound through the right speaker, it seemed to act like a ticking clock at one time.
I turned the amps off and swapped them over, now so far it hasn't reoccurred in the left speaker. I leave my amps on 24/7, is it possible that turning them off (10 min's) cured the problem. My preamp is a passive TVC and the problem wasn't eliminated by switching to another input or turning all sources off. Its possible it could be the right speaker, but as it hasn't yet reoccurred I don't really know. Thanks.
