@bobheinatz you have some good interconnects and speaker cables that you should feel very good about. What you are about to do is spend additional funds for a different sound and jump down a dark rabbit hole. With that said, I'm very guilty of having done that several times myself. If I were you I'd phone Collin at Gestalt Audio Design in Nashville TN and discuss this with him. He can give you some excellent choices and he is a wealth of information.
In addition to that make sure you upgrade your power cords and make sure you are using one or two dedicated circuits with good AC outlets. Your power filtration is very important.
