Agreeing w Elizabeth on cleaning power first. You have a good pre. All a softer tube pre could do for you is roll off the top which you’ll soon find boring. A neutral tube pre will leave you in the same place.
I have found the latest generation of AQ power products to accomplish what you are looking for without rolling the highs off. In fact the Hurricane power cord is the first high end cord that I can say provided fundamental benefits along the lines you are looking for. I am somewhat sceptical on power cords but not this one. FWIW
