Quiet but highly audiable and annoying hissing from amp?

Hi

I have an Audiolab 8000s.

Recently I have noticed that one of the speakers is making a constant hissing (from the tweeter and upper of the two cones that supply the midrange sound).

It appears to be the amp that is sending a bad signal as:

-The volume of the hissing changes as the volume on the amp is moved
-The hissing is audiable even when the amp is at the lowest volume setting
-Disconnecting everything from the amp makes no difference to the sound
-When playing a CD, the hissing is still audiable over the music during periods of silence.

Any ideas as to what it is?

Thanks
