Tice Power Block

I have used an original Tice Power Block for over 2 decades, with nice satisfaction.  Having become aware over the years that upgrading power cords throughout y system has had benefits, I wonder if doing the same to the Tice Power Block itself might be useful; unfortunately the original model did not have a removable power cord.....any thoughts?
It could help and there is really only one way to find out and that is to try it out in your own system.  Also, later Tice Power Block and Titans came with an upgrades TPT power cords. 
most upgrade power cords are sealed and soldered at the component end......I need suggestion for one that might be amenable to surgery....
