Question preamp with

Hi Guys,

I would like to start a new project. I would like to build a preamplifier similar to a GainGard 47labs, I mean I would just to have gain stage. My amplifiers are 100Watts, 100KOhms input, so very easy to drive.

I wonder whether there is some project going on which makes line stage preamp using opamps.

I hope somebody can help,
