KK hiss ?

[malpa]

hello to everyone
there is a hiss coming out of my speakers, tweeters mainly so its a high frequency noise and its always there as soon as i power on my KK and KCT( when receiced a signal),

- KCT off(before the signal received), KK on = no hiss.
- KCT on and KK off = very quiet hiss almost non.
- KCT on ,KK on louder hiss i can hear it from 1m ( cant hear it when listening to the music).
- both on with the source disconnected still hiss.
the hiss is not dependent on the volume, does not get louder when volume increased.
i try to separate all the cables from each other and its still there.
is it normal?, have anyone experienced similar issue ?
or should i just forget about it, as i said it doesn't affect the performance.
thanx for any answer, best.

I am guessing that in the above you meant "as I said, it doesn't"?

From your description of it, it sounds perfectly normal. There is hiss in all electronics, there's no way to remove it completely.

If I put my ear very close to the tweeters in my ATCs I can also hear a slight hiss from the KK. I cannot hear it from my normal listening position and it doesn't change with volume level. As I have had it with three different KKs I would certainly say it is normal.
