Default Simaudio PSP phono amp mods?

I have a Sim Audio PSP phono preamp.
After opening it up, one quickly realizes they charge a boat load of money for a nice chassis and not too much else...
Anyway, I was thinking of upgrading parts on it.
Also, it's output is way too high for my Grado Platinum and I would like to lower the gain.
Only problem is I am clueless as to what to change.
Can anyone help with this? I included a top side photo.
I'll include a bottom side photo in my next post.

I was even thinking of tossing the bd and putting something else in it's place. But I want to try improving the present board first. Suggestions?

Can I swap anything better in or will I mess something up?
