I have no white noise at all, are you running the loudspeaker cables over the power cables by accident? Otherwise start by disconnecting all devices and reconnecting them one by one
quiet hiss in backround?
i have a quiet hissing from speakers when no music is playing and i am sure it is there when music is on but hard to hear. it drives me crazy! i always attributed it to normal noise from my amplifier but i wonder what you folks think? is it a power issue? the amp is a krell fpb600c, dedicated line, no power conditioning (a small quiet line by audio prism (parallel power line filter) is all. is this normal?
