If it can’t be heard while music is playing, then why worry....there is some degree of hiss or noise in ever system. It depends how sensitive you are too it. My tubed phono preamp is noisier than my solid State. However, once the music is playing, I'll take the tubed phono any day...
Help with hiss
Hello Friends,
My speakers have developed an audible hiss that I am trying to chase down. The hiss can be heard from across the room and while music is being played. Sometimes, the hiss is pulsating and sometimes constant. It occurs at all hours, perhaps less so in the early morning. Sometimes there is no hiss at all and everything is silent. It is an intermittent issue that is unpredictable.
My speakers are powered by mono block amplifiers. Both speakers exhibit the exact same behavior. The monos are plugged directly into the wall outlet. I also plugged them into a PS Audio AV Power Center with no relief. I changed power cords with no relief. No other piece of gear is on, although all are plugged in and some are in standby. I turned one mono off of course stopping the hiss in that speaker. The other continued to hiss. In reverse, same result.
This is not a “hum” (like from a ground loop). It is the same hiss that you can hear with your ear next to the tweeter but much louder.
I’m happy to answer any questions at all to help me resolve this. Thank you in advance.
