All of my systems have had some sort of very faint hiss when no music is playing, and I put my ear right up to the tweeter. It’s a good way to confirm that the tweeters are working, and should pose zero issue when listening to music. No problem if it's not loud enough to be heard across the room, or when music is playing.
Very faint hiss from tweeter
I just put a new system together and noticed that when no music is playing, if I put my ear very close to the tweeter on either speaker, there is a very faint hiss sound. Is this indicative of a problem? Its not audible unless my ear is very close to the tweeter, but I wonder if its polluting amplified sound when I play music. Should a system be stone cold silent when powered on with no music playing?
