Preamp Turned Down/Amplifer Noise

When I turn down my preamp all the way (doesnt have a mute) I can hear what sounds like a hum through my amplifier. This could be transformer hum I am not sure. With the preamp volume all the way down should there be dead silence through the speaker. Is this a ground loop issue?

I have had the this noise when i was using speakers with a high sensitivity rating like 90 db and above. They seem to show more electronic noise.
If your pre-amp has an adjustable gain like a surround pre-amp or a receiver try setting it to a lower gain.

Good luck !!
