wanted: preamp with bass equalization

I am looking to get a pre-amp and amp or very high quality. I have found that the equalization of pre-amps are usually very good, and require no coloring, except when it comes to bass. Depending on the source music and the overall volume, I find that I always like to be able to juice up the bass a little bit. I will have some very good full range speakers, so ther problem will not be there.

It seems that the solution would be to have some sort of bass preamp processor that can boost the bass (with some equalization there, and perhaps some other esoteric changes.)

Any ideas?
