Ernewald,
I would start with a few dedicated 20 amp circuits if you don't have them. The correct power conditionor could do wonders for anyones system however that is a debatable topic, it worked wonders for me.
I have also demoed different power cords, where some were wonderful and some did nothing for my system. It's possible that the power cords you purchased work well for other systems but not in yours. Sometimes you have to demo different brands to find the one that works well for you.
