I'm hoping someone who knows the ins and outs of tuning a parametric EQ can respond. I currently am using the AVHP7600DVD and will be installing the Z1 tomorrow. I don't think I ever really understood the Parametric EQ and I think my ears and my system have suffered long enough. I plan on tuning the Z1 correctly but need help. Maybe someone can help. Please not a bunch off buzz words and jargon I can't understand, explain as if I was one of your Grand Parents even though I'm only 33 years old. Any help would be appreciated. Thanks
