I dont eq or compress, you need a clean sample meaning nutral eq'ing ( like none, all knobs centered ). This is because the sample will be processed throughout the production, form comes first, logicaly followed by signal processing ( eq+dynamics ) in the mix. Keep the samples as clean as possible and record them as loud as possible without giving your VU readings pms ( all in the red ) and dont forget that all you can do to a sample comes in the end except your not dealing with the sample but the track where the sample is featured. It's a non destructive approach, just like monitor mixing.
