Very slight "Hiss"

When I press my ear next to the tweeter, either channel or input selection, I hear a "hiss". I have tried chokes, and changed physical position of IC's. However, I noticed that if I select an input that has nothing connected to it, the hiss increases. The hiss is small, but it really bugs me all the same. Might there be a way to eliminate it??
Thanks.

It is most likely coming from the pre-amp, since it changes with input selection. Some components are quieter than others. I have experienced it through the years with differnt components. Nothing I tried helped. e.g. ground changes, cable routing, component placement, etc. I know it bugs you but I think you are opening a can of worms that could ultimately cost you your sanity. Luckily I gave up before I got to the point..hee hee ha ha ho ho their coming to take me away ha ha:)

I get the message - OCD!! I mean, my sweet-spot is 15' away, I cant hear the hiss there, but I was wondering if it should be silent. The source component is a Krell KAV 400xi.

Thanks

I bet if you stand on your head for an hour you'll get a headache too, but why would you ever do that?

In normal use why would you ever press your ear next to the tweeter?

I agree with Tpreaves
