pioneer sx-1980 and audiocontrol c-22 eq

I have a pioneer sx1980 in perfect shape, its been fully serviced and good for another 30yrs, well its lasted me for 20yrs. do I really need to use my audiocontrol eq? I find it very hard at adjusting. it has 8sliders for bass,mid 6 sliders, treble 6sliders. im using my sansui spx-x9000 and they sound great at flat on my receiver. I use to have my cerwin-vega sls215 but my wife had me get rid of them because of down sizing. I do miss them, however the sansuis still look and sound great, not the bass like the vegs. thanks.
