It's been a long time since I was at all active in Amateur Radio.
But from my memory, which is mostly washed away by gin and vermouth,
some, if not all, Hams are avid electronic tinkerers. The web is filled
with little preamp circuits you can build with three transistors and
a 9v battery, and can put in an Altoids tin. Wouldn't this be a better
solution than fooling with software. How many of them to you need,
after all?

Here's a list of some you might look at:

http://www.passdiy.com/

   ($5 mic preamp, which the article claims competes
    favorably with a $1500 preamp. I have no idea
    if it is smoke or mirrors or both.)

   (Related to the previous)

I got these by searching for "preamp" on digg.

P.S. After I wrote this reply I actually looked at the
      other replies, so this is not completely relevant.
