I think graphic equalizers are mostly used as band-aids for bad systems. Where there's a legitimate need for boosting or cutting, parametric equalizers are more suitable. They also need far fewer components, so are much more practical to DIY.

But, first look at the quality of the op-amps and coupling capacitors, and the power supply. Those can have measurable effects on the sound.
