Manual gain controls on Hafler 9180


Yes folks, you read it right here! I have a Hafler 9180. "Still running after all these years..." (since 1994)
Can afford to replace but the sound pleases me so it remains. 

Enough background and introduction: the point of this post> 

I know nothing about audio electronics, but am willing to learn...)
The Hafler has a manual gain control for each channel located on the front panel. Is there an "optimal" setting for these? What sound differences will I hear by adjusting these one way or another?

Thanks to all learned folks responding to my query.!

I would try to position the controls on the amp such that I advance the volume control on the preamp to about the 2 o'clock position for the loudest desired system volume.  Hopefully this can be done such that the attenuation on the amp is minimal.
