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.

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

Elizabeth is correct. No electronics can achieve zero noise. What you guys are hearing is residual thermal hiss, which occurs in all electronics, regardless of quality or price. As long as hiss is inaudible from the listening position on the quietest music passages, there is no problem.
