The LM-386 was not designed to be a audio pre-amp and is a rather poor choice for a pre-amp. It was/is an audio output chip for low power applications like transistor radios, cassette decks, etc. driving a small speaker. It's not a bad chip, but certainly not of the highest audio quality and specifications.
From the same era the National LM-387 ( http://www.experimentalistsanonymous.com/diy/Datasheets/LM387.pdf
) was designed for audio pre-amp applications and had better noise specs, etc.
Today most quality pre-amp circuits are just designed with the plentiful and better avalible op-amps which can be selected for whatever specific specifications are important for a specific application.
My favorite source for audio circuits is the Elliott sound products site. Here is the section on pre-amp circuits:http://sound.westhost.com/projects-2.htm
That web site is just full of very useful information that applies to much more then just audio applications.
