Every pre has a best setting. Sometimes they are designed for that setting
and have a detent or are at 0, other times you just find out by trying. I
have a cheap one with 0, 10, 20 and 30db gain settings where the 30 db
setting is quieter that the 20db setting... Your 1010 should be better
than that.

Something to watch out for though... just because your pre likes a line
level of +4 or +8 doesn't mean the card can handle it, some start clipping
at around -10, even with the input level turned down. If there is a gain
or buffer stage before the level control, that can clip even with what
looks like a low level inside the computer. That's what ears are for. No
matter how good the equipment is, in the end you have to listen to it and
try settings till it sounds best. Mudita24 or envy24control has lots of
meters to help you set your 1010 up. They give a pretty good idea of what
your card can handle.

The original envy24control can be found in alsa-tools-gui and the updated
version mudita24 has it's own package.
